--- _id: '12068' abstract: - lang: eng text: Metallaphotocatalysis typically requires a photocatalyst to harness the energy of visible-light and transfer it to a transition metal catalyst to trigger chemical reactions. The most prominent example is the merger of photo- and nickel catalysis that unlocked various cross-couplings. However, the high reactivity of excited photocatalyst can lead to unwanted side reactions thus limiting this approach. Here we show that a bipyridine ligand that is subtly decorated with two carbazole groups forms a nickel complex that absorbs visible-light and promotes several carbon–heteroatom cross-couplings in the absence of an exogenous photocatalysts. The ligand can be polymerized in a simple one-step procedure to afford a porous organic polymer that can be used for heterogeneous nickel catalysis in the same reactions. The material can be easily recovered and reused multiple times maintaining high catalytic activity and selectivity. article_processing_charge: No author: - first_name: Cristian full_name: Cavedon, Cristian last_name: Cavedon - first_name: Sebastian full_name: Gisbertz, Sebastian last_name: Gisbertz - first_name: Sarah full_name: Vogl, Sarah last_name: Vogl - first_name: Noah full_name: Richter, Noah last_name: Richter - first_name: Stefanie full_name: Schrottke, Stefanie last_name: Schrottke - first_name: Christian full_name: Teutloff, Christian last_name: Teutloff - first_name: Peter H. full_name: Seeberger, Peter H. last_name: Seeberger - first_name: Arne full_name: Thomas, Arne last_name: Thomas - first_name: Bartholomäus full_name: Pieber, Bartholomäus id: 93e5e5b2-0da6-11ed-8a41-af589a024726 last_name: Pieber orcid: 0000-0001-8689-388X citation: ama: Cavedon C, Gisbertz S, Vogl S, et al.

Here we show that the redox potential of a carbon nitride photocatalyst (CN-OA-m) can be tuned by changing the irradiation wavelength to generate electron holes with different oxidation potentials. This tuning was the key to realizing photo-chemo-enzymatic cascades that give either the (S)- or the (R)-enantiomer of phenylethanol. In combination with an unspecific peroxygenase from Agrocybe aegerita, green light irradiation of CN-OA-m led to the enantioselective hydroxylation of ethylbenzene to (R)-1-phenylethanol (99% ee). In contrast, blue light irradiation triggered the photocatalytic oxidation of ethylbenzene to acetophenone, which in turn was enantioselectively reduced with an alcohol dehydrogenase from Rhodococcus ruber to form (S)-1-phenylethanol (93% ee). article_processing_charge: No author: - first_name: Luca full_name: Schmermund, Luca last_name: Schmermund - first_name: Susanne full_name: Reischauer, Susanne last_name: Reischauer - first_name: Sarah full_name: Bierbaumer, Sarah last_name: Bierbaumer - first_name: Christoph full_name: Winkler, Christoph last_name: Winkler - first_name: Alba full_name: Diaz-Rodriguez, Alba last_name: Diaz-Rodriguez - first_name: Lee J. full_name: Edwards, Lee J. last_name: Edwards - first_name: Selin full_name: Kara, Selin last_name: Kara - first_name: Tamara full_name: Mielke, Tamara last_name: Mielke - first_name: Jared full_name: Cartwright, Jared last_name: Cartwright - first_name: Gideon full_name: Grogan, Gideon last_name: Grogan - first_name: Bartholomäus full_name: Pieber, Bartholomäus id: 93e5e5b2-0da6-11ed-8a41-af589a024726 last_name: Pieber orcid: 0000-0001-8689-388X - first_name: Wolfgang full_name: Kroutil, Wolfgang last_name: Kroutil citation: ama: Schmermund L, Reischauer S, Bierbaumer S, et al.

Here, we probe the nanoscale electronic structure of the Mott insulator Sr₂IrO₄δ with low-temperature scanning tunneling microscopy and find an enhanced local density of states (LDOS) inside the Mott gap at the location of individual defects which we interpret as defects at apical oxygen sites. A chiral behavior in the topography for those defects has been observed. We also visualize the local enhanced conductance arising from the overlapping of defect states which induces finite LDOS inside of the Mott gap. By combining these findings with the typical spatial extension of isolated defects of about 2 nm, our results indicate that the insulator-to-metal transition in Sr₂IrO₄−δ could be percolative in nature. article_number: '023075' article_processing_charge: No article_type: original author: - first_name: Zhixiang full_name: Sun, Zhixiang last_name: Sun - first_name: Jose M. full_name: Guevara, Jose M. last_name: Guevara - first_name: Steffen full_name: Sykora, Steffen last_name: Sykora - first_name: Ekaterina full_name: Paerschke, Ekaterina id: 8275014E-6063-11E9-9B7F-6338E6697425 last_name: Paerschke orcid: 0000-0003-0853-8182 - first_name: Kaustuv full_name: Manna, Kaustuv last_name: Manna - first_name: Andrey full_name: Maljuk, Andrey last_name: Maljuk - first_name: Sabine full_name: Wurmehl, Sabine last_name: Wurmehl - first_name: Jeroen full_name: van den Brink, Jeroen last_name: van den Brink - first_name: Bernd full_name: Büchner, Bernd last_name: Büchner - first_name: Christian full_name: Hess, Christian last_name: Hess citation: ama: Sun Z, Guevara JM, Sykora S, et al.

Here, we combine RNA-seq and ATAC-seq to define changes in gene expression and chromatin accessibility. Activation of cell-surface or intracellular receptor-mediated immunity, or both, increases chromatin accessibility at induced defence genes. Analysis of ATAC-seq and RNA-seq data combined with publicly available information on transcription factor DNA-binding motifs enabled comparison of individual gene regulatory networks activated by cell-surface or intracellular receptor-mediated immunity, or by both.

We applied a physically based, energy balance melt model at five on-glacier sites within the Peruvian Cordilleras Blanca and Vilcanota. Net shortwave radiation dominates the energy balance, and despite this flux being higher in the dry season, melt rates are lower due to losses from net longwave radiation and the latent heat flux. The sensible heat flux is a relatively small contributor to melt energy. At three of the sites the wet season snowpack was discontinuous, forming and melting within a daily to weekly timescale, and resulting in highly variable melt rates closely related to precipitation dynamics. Cold air temperatures due to a strong La Niña year at Shallap Glacier (Cordillera Blanca) resulted in a continuous wet season snowpack, significantly reducing wet season ablation. Sublimation was most important at the highest site in the accumulation zone of the Quelccaya Ice Cap (Cordillera Vilcanota), accounting for 81% of ablation, compared to 2%–4% for the other sites. Air temperature and precipitation inputs were perturbed to investigate the climate sensitivity of the five glaciers. At the lower sites warmer air temperatures resulted in a switch from snowfall to rain, so that ablation was increased via the decrease in albedo and increase in net shortwave radiation. At the top of Quelccaya Ice Cap warming caused melting to replace sublimation so that ablation increased nonlinearly with air temperature. article_number: e2021JD034911 article_processing_charge: No article_type: original author: - first_name: Catriona L. full_name: Fyffe, Catriona L. last_name: Fyffe - first_name: Emily full_name: Potter, Emily last_name: Potter - first_name: Stefan full_name: Fugger, Stefan last_name: Fugger - first_name: Andrew full_name: Orr, Andrew last_name: Orr - first_name: Simone full_name: Fatichi, Simone last_name: Fatichi - first_name: Edwin full_name: Loarte, Edwin last_name: Loarte - first_name: Katy full_name: Medina, Katy last_name: Medina - first_name: Robert Å. full_name: Hellström, Robert Å. last_name: Hellström - first_name: Maud full_name: Bernat, Maud last_name: Bernat - first_name: Caroline full_name: Aubry‐Wake, Caroline last_name: Aubry‐Wake - first_name: Wolfgang full_name: Gurgiser, Wolfgang last_name: Gurgiser - first_name: L.

Hydrological data products were generated taking advantage of the synergies of European and Chinese data assets and space-borne observation systems. Energy-budget-based glacier mass balance and hydrological models driven by satellite observations were developed. These models can be applied to describe glacier-melt contribution to river flow. Satellite hydrological data products were used for forcing, calibration, validation and data assimilation in distributed river basin models. A pilot study was carried out on the Red River basin. Multiple hydrological data products were generated using the data collected by Chinese satellites. A new Evapo-Transpiration (ET) dataset from 2000 to 2018 was generated, including plant transpiration, soil evaporation, rainfall interception loss, snow/ice sublimation and open water evaporation. Higher resolution data were used to characterize glaciers and their response to environmental forcing. These studies focused on the Parlung Zangbo Basin, where glacier facies were mapped with GaoFeng (GF), Sentinal-2/Multi-Spectral Imager (S2/MSI) and Landsat8/Operational Land Imager (L8/OLI) data. The geodetic mass balance was estimated between 2000 and 2017 with Zi-Yuan (ZY)-3 Stereo Images and the SRTM DEM. Surface velocity was studied with Landsat5/Thematic Mapper (L5/TM), L8/OLI and S2/MSI data over the period 2013–2019. An updated method was developed to improve the retrieval of glacier albedo by correcting glacier reflectance for anisotropy, and a new dataset on glacier albedo was generated for the period 2001–2020. A detailed glacier energy and mass balance model was developed with the support of field experiments at the Parlung No. 4 Glacier and the 24 K Glacier, both in the Tibetan Plateau. Besides meteorological measurements, the field experiments included glaciological and hydrological measurements. The energy balance model was formulated in terms of enthalpy for easier treatment of water phase transitions. The model was applied to assess the spatial variability in glacier melt. In the Parlung No. 4 Glacier, the accumulated glacier melt was between 1.5 and 2.5 m w.e. in the accumulation zone and between 4.5 and 6.0 m w.e. in the ablation zone, reaching 6.5 m w.e. at the terminus. The seasonality in the glacier mass balance was observed by combining intensive field campaigns with continuous automatic observations. The linkage of the glacier and snowpack mass balance with water resources in a river basin was analyzed in the Chiese (Italy) and Heihe (China) basins by developing and applying integrated hydrological models using satellite retrievals in multiple ways. The model FEST-WEB was calibrated using retrievals of Land Surface Temperature (LST) to map soil hydrological properties. A watershed model was developed by coupling ecohydrological and socioeconomic systems. Integrated modeling is supported by an updated and parallelized data assimilation system. The latter exploits retrievals of brightness temperature (Advanced Microwave Scanning Radiometer, AMSR), LST (Moderate Resolution Imaging Spectroradiometer, MODIS), precipitation (Tropical Rainfall Measuring Mission (TRMM) and FengYun (FY)-2D) and in-situ measurements. In the case study on the Red River Basin, a new algorithm has been applied to disaggregate the SMOS (Soil Moisture and Ocean Salinity) soil moisture retrievals by making use of the correlation between evaporative fraction and soil moisture. article_number: '5122' article_processing_charge: No article_type: letter_note author: - first_name: Massimo full_name: Menenti, Massimo last_name: Menenti - first_name: Xin full_name: Li, Xin last_name: Li - first_name: Li full_name: Jia, Li last_name: Jia - first_name: Kun full_name: Yang, Kun last_name: Yang - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti - first_name: Marco full_name: Mancini, Marco last_name: Mancini - first_name: Jiancheng full_name: Shi, Jiancheng last_name: Shi - first_name: Maria José full_name: Escorihuela, Maria José last_name: Escorihuela - first_name: Chaolei full_name: Zheng, Chaolei last_name: Zheng - first_name: Qiting full_name: Chen, Qiting last_name: Chen - first_name: Jing full_name: Lu, Jing last_name: Lu - first_name: Jie full_name: Zhou, Jie last_name: Zhou - first_name: Guangcheng full_name: Hu, Guangcheng last_name: Hu - first_name: Shaoting full_name: Ren, Shaoting last_name: Ren - first_name: Jing full_name: Zhang, Jing last_name: Zhang - first_name: Qinhuo full_name: Liu, Qinhuo last_name: Liu - first_name: Yubao full_name: Qiu, Yubao last_name: Qiu - first_name: Chunlin full_name: Huang, Chunlin last_name: Huang - first_name: Ji full_name: Zhou, Ji last_name: Zhou - first_name: Xujun full_name: Han, Xujun last_name: Han - first_name: Xiaoduo full_name: Pan, Xiaoduo last_name: Pan - first_name: Hongyi full_name: Li, Hongyi last_name: Li - first_name: Yerong full_name: Wu, Yerong last_name: Wu - first_name: Baohong full_name: Ding, Baohong last_name: Ding - first_name: Wei full_name: Yang, Wei last_name: Yang - first_name: Pascal full_name: Buri, Pascal last_name: Buri - first_name: Michael J. full_name: McCarthy, Michael J. last_name: McCarthy - first_name: Evan S. full_name: Miles, Evan S. last_name: Miles - first_name: Thomas E. full_name: Shaw, Thomas E. last_name: Shaw - first_name: Chunfeng full_name: Ma, Chunfeng last_name: Ma - first_name: Yanzhao full_name: Zhou, Yanzhao last_name: Zhou - first_name: Chiara full_name: Corbari, Chiara last_name: Corbari - first_name: Rui full_name: Li, Rui last_name: Li - first_name: Tianjie full_name: Zhao, Tianjie last_name: Zhao - first_name: Vivien full_name: Stefan, Vivien last_name: Stefan - first_name: Qi full_name: Gao, Qi last_name: Gao - first_name: Jingxiao full_name: Zhang, Jingxiao last_name: Zhang - first_name: Qiuxia full_name: Xie, Qiuxia last_name: Xie - first_name: Ning full_name: Wang, Ning last_name: Wang - first_name: Yibo full_name: Sun, Yibo last_name: Sun - first_name: Xinyu full_name: Mo, Xinyu last_name: Mo - first_name: Junru full_name: Jia, Junru last_name: Jia - first_name: Achille Pierre full_name: Jouberton, Achille Pierre last_name: Jouberton - first_name: Marin full_name: Kneib, Marin last_name: Kneib - first_name: Stefan full_name: Fugger, Stefan last_name: Fugger - first_name: Nicola full_name: Paciolla, Nicola last_name: Paciolla - first_name: Giovanni full_name: Paolini, Giovanni last_name: Paolini citation: ama: Menenti M, Li X, Jia L, et al.

Here, we present altitudinally-resolved specific mass balances (surface, internal, and basal combined) for 5527 glaciers in High Mountain Asia for 2000–2016, derived by correcting observed glacier thinning patterns for mass redistribution due to ice flow. We find that 41% of glaciers accumulated mass over less than 20% of their area, and only 60% ± 10% of regional annual ablation was compensated by accumulation. Even without 21st century warming, 21% ± 1% of ice volume will be lost by 2100 due to current climatic-geometric imbalance, representing a reduction in glacier ablation into rivers of 28% ± 1%. The ablation of glaciers in the Himalayas and Tien Shan was mostly unsustainable and ice volume in these regions will reduce by at least 30% by 2100. The most important and vulnerable glacier-fed river basins (Amu Darya, Indus, Syr Darya, Tarim Interior) were supplied with >50% sustainable glacier ablation but will see long-term reductions in ice mass and glacier meltwater supply regardless of the Karakoram Anomaly. article_number: '2868' article_processing_charge: No article_type: original author: - first_name: Evan full_name: Miles, Evan last_name: Miles - first_name: Michael full_name: McCarthy, Michael last_name: McCarthy - first_name: Amaury full_name: Dehecq, Amaury last_name: Dehecq - first_name: Marin full_name: Kneib, Marin last_name: Kneib - first_name: Stefan full_name: Fugger, Stefan last_name: Fugger - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: Miles E, McCarthy M, Dehecq A, Kneib M, Fugger S, Pellicciotti F.

Previous studies have shown that their number and relative area can change considerably from year to year, but this variability has not been explored, in part because available cliff observations are irregular. Here, we systematically mapped and tracked ice cliffs across four debris-covered glaciers in High Mountain Asia for every late ablation season from 2009 to 2019 using high-resolution multi-spectral satellite imagery. We then quantified the processes occurring at the feature scale to train a stochastic birth-death model to represent the cliff population dynamics. Our results show that while the cliff relative area can change by up to 20% from year to year, the natural long-term variability is constrained, thus defining a glacier-specific cliff carrying capacity. In a subsequent step, the inclusion of external drivers related to climate, glacier dynamics, and hydrology highlights the influence of these variables on the cliff population dynamics, which is usually not a direct one due to the complexity and interdependence of the processes taking place at the glacier surface. In some extreme cases (here, a glacier surge), these external drivers may lead to a reorganization of the cliffs at the glacier surface and a change in the natural variability. These results have implications for the melt of debris-covered glaciers, in addition to showing the high rate of changes at their surface and highlighting some of the links between cliff population and glacier state. article_number: e2021JF006179 article_processing_charge: No article_type: original author: - first_name: M. full_name: Kneib, M. last_name: Kneib - first_name: E.

Removing the need for local meteorological data in the debris thickness estimation workflow could improve the versatility and spatiotemporal application of debris thickness estimation. We evaluate the use of regional reanalysis data to derive debris thickness for two mountain glaciers using a surface energy-balance model. Results forced using ERA-5 agree with AWS-derived estimates to within 0.01 ± 0.05 m for Miage Glacier, Italy, and 0.01 ± 0.02 m for Khumbu Glacier, Nepal. ERA-5 data were then used to estimate spatiotemporal changes in debris thickness over a ~20-year period for Miage Glacier, Khumbu Glacier and Haut Glacier d'Arolla, Switzerland. We observe significant increases in debris thickness at the terminus for Haut Glacier d'Arolla and at the margins of the expanding debris cover at all glaciers. While simulated debris thickness was underestimated compared to point measurements in areas of thick debris, our approach can reconstruct glacier-scale debris thickness distribution and its temporal evolution over multiple decades. We find significant changes in debris thickness over areas of thin debris, areas susceptible to high ablation rates, where current knowledge of debris evolution is limited. article_processing_charge: No article_type: original author: - first_name: Rebecca L. full_name: Stewart, Rebecca L. last_name: Stewart - first_name: Matthew full_name: Westoby, Matthew last_name: Westoby - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti - first_name: Ann full_name: Rowan, Ann last_name: Rowan - first_name: Darrel full_name: Swift, Darrel last_name: Swift - first_name: Benjamin full_name: Brock, Benjamin last_name: Brock - first_name: John full_name: Woodward, John last_name: Woodward citation: ama: Stewart RL, Westoby M, Pellicciotti F, et al.

Here we calculate the effect of supraglacial ice cliffs on the mass balance of all glaciers in a Himalayan catchment, using a process-based ice cliff melt model. We show that ice cliffs are responsible for higher than expected thinning rates of debris-covered glacier tongues, leading to an underestimation of their ice mass loss of 17% ± 4% in the catchment if not considered. We also show that cliffs do enhance melt where other processes would suppress it, that is, at high elevations, or where debris is thick, and that they contribute relatively more to glacier mass loss if oriented north. Our approach provides a key contribution to our understanding of the mass losses of debris-covered glaciers, and a new quantification of their catchment wide melt and mass balance. article_number: e2020GL092150 article_processing_charge: No article_type: letter_note author: - first_name: Pascal full_name: Buri, Pascal last_name: Buri - first_name: Evan S. full_name: Miles, Evan S. last_name: Miles - first_name: Jakob F. full_name: Steiner, Jakob F. last_name: Steiner - first_name: Silvan full_name: Ragettli, Silvan last_name: Ragettli - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: Buri P, Miles ES, Steiner JF, Ragettli S, Pellicciotti F.

We present a new dataset of distributed Ta for three glaciers of different size in the south-east Tibetan Plateau during two monsoon-dominated summer seasons. We compare on-glacier Ta to ambient Ta extrapolated from several local off-glacier stations. We parameterise the along-flowline sensitivity of Ta on these glaciers to changes in off-glacier temperatures (referred to as “temperature sensitivity”) and present the results in the context of available distributed on-glacier datasets around the world. Temperature sensitivity decreases rapidly up to 2000–3000 m along the down-glacier flowline distance. Beyond this distance, both the Ta on the Tibetan glaciers and global glacier datasets show little additional cooling relative to the off-glacier temperature. In general, Ta on small glaciers (with flowline distances <1000 m) is highly sensitive to temperature changes outside the glacier boundary layer. The climatology of a given region can influence the general magnitude of this temperature sensitivity, though no strong relationships are found between along-flowline temperature sensitivity and mean summer temperatures or precipitation. The terminus of some glaciers is affected by other warm-air processes that increase temperature sensitivity (such as divergent boundary layer flow, warm up-valley winds or debris/valley heating effects) which are evident only beyond ∼70 % of the total glacier flowline distance. Our results therefore suggest a strong role of local effects in modulating temperature sensitivity close to the glacier terminus, although further work is still required to explain the variability of these effects for different glaciers. article_processing_charge: No article_type: original author: - first_name: Thomas E. full_name: Shaw, Thomas E. last_name: Shaw - first_name: Wei full_name: Yang, Wei last_name: Yang - first_name: Álvaro full_name: Ayala, Álvaro last_name: Ayala - first_name: Claudio full_name: Bravo, Claudio last_name: Bravo - first_name: Chuanxi full_name: Zhao, Chuanxi last_name: Zhao - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: 'Shaw TE, Yang W, Ayala Á, Bravo C, Zhao C, Pellicciotti F.

These datasets are often derived using operator-biased and time-consuming manual delineation approaches, despite the recent emergence of semi-automatic mapping methods. These methods have used elevation or multispectral data, but the varying slope and mixed spectral signal of these dynamic features makes the transferability of these approaches particularly challenging. We develop three semi-automated and objective new approaches, based on the Spectral Curvature and Linear Spectral Unmixing of multispectral images, to map these features at a glacier to regional scale. The transferability of each method is assessed by applying it to three sites in the Himalaya, where debris-covered glaciers are widespread, with varying lithologic, glaciological and climatic settings, and encompassing different periods of the melt season. We develop the new methods keeping in mind the wide range of remote sensing platforms currently in use, and focus in particular on two products: we apply the three approaches at each site to near-contemporaneous atmospherically-corrected Pléiades (2 m resolution) and Sentinel-2 (10 m resolution) images and assess the effects of spatial and spectral resolution on the results. We find that the Spectral Curvature method works best for the high spatial resolution, four band Pléaides images, while a modification of the Linear Spectral Unmixing using the scaling factor of the unmixing is best for the coarser spatial resolution, but additional spectral information of Sentinel-2 products. In both cases ice cliffs are mapped with a Dice coefficient higher than 0.48. Comparison of the Pléiades results with other existing methods shows that the Spectral Curvature approach performs better and is more robust than any other existing automated or semi-automated approaches. Both methods outline a high number of small, sometimes shallow-sloping and thinly debris-covered ice patches that differ from our traditional understanding of cliffs but may have non-negligible impact on the mass balance of debris-covered glaciers. Overall these results pave the way for large scale efforts of ice cliff mapping that can enable inclusion of these features in debris-covered glacier melt models, as well as allow the generation of multiple datasets to study processes of cliff formation, evolution and decline.' article_number: '112201' article_processing_charge: No article_type: original author: - first_name: M. full_name: Kneib, M. last_name: Kneib - first_name: E.S. full_name: Miles, E.S. last_name: Miles - first_name: S. full_name: Jola, S. last_name: Jola - first_name: P. full_name: Buri, P. last_name: Buri - first_name: S. full_name: Herreid, S. last_name: Herreid - first_name: A. full_name: Bhattacharya, A. last_name: Bhattacharya - first_name: C.S. full_name: Watson, C.S. last_name: Watson - first_name: T. full_name: Bolch, T. last_name: Bolch - first_name: D. full_name: Quincey, D. last_name: Quincey - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: Kneib M, Miles ES, Jola S, et al.

Remote sensing techniques are efficient means to retrieve glacier surface albedo over large and inaccessible areas and to study its variability. However, corrections of anisotropic reflectance of glacier surface have been established for specific shortwave bands only, such as Landsat 5 Thematic Mapper (L5/TM) band 2 and band 4, which is a major limitation of current retrievals of glacier broadband albedo. In this study, we calibrated and evaluated four anisotropy correction models for glacier snow and ice, applicable to visible, near-infrared and shortwave-infrared wavelengths using airborne datasets of Bidirectional Reflectance Distribution Function (BRDF). We then tested the ability of the best-performing anisotropy correction model, referred to from here on as the ‘updated model’, to retrieve albedo from L5/TM, Landsat 8 Operational Land Imager (L8/OLI) and Moderate Resolution Imaging Spectroradiometer (MODIS) imagery, and evaluated these results with field measurements collected on eight glaciers around the world. Our results show that the updated model: (1) can accurately estimate anisotropic factors of reflectance for snow and ice surfaces; (2) generally performs better than prior approaches for L8/OLI albedo retrieval but is not appropriate for L5/TM; (3) generally retrieves MODIS albedo better than the MODIS standard albedo product (MCD43A3) in both absolute values and glacier albedo temporal evolution, i.e., exhibiting both fewer gaps and better agreement with field observations. As the updated model enables anisotropy correction of a maximum of 10 multispectral bands and is implemented in Google Earth Engine (GEE), it is promising for observing and analyzing glacier albedo at large spatial scales.' article_number: '1714' article_processing_charge: No article_type: original author: - first_name: Shaoting full_name: Ren, Shaoting last_name: Ren - first_name: Evan S. full_name: Miles, Evan S. last_name: Miles - first_name: Li full_name: Jia, Li last_name: Jia - first_name: Massimo full_name: Menenti, Massimo last_name: Menenti - first_name: Marin full_name: Kneib, Marin last_name: Kneib - first_name: Pascal full_name: Buri, Pascal last_name: Buri - first_name: Michael J. full_name: McCarthy, Michael J. last_name: McCarthy - first_name: Thomas E. full_name: Shaw, Thomas E. last_name: Shaw - first_name: Wei full_name: Yang, Wei last_name: Yang - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: Ren S, Miles ES, Jia L, et al.

Here we investigate the underlying mechanisms of the texture evolution in an evaporation-induced colloidal assembly process through experiments, modeling, and theoretical analysis. In this widely used approach to obtain large-area colloidal crystals, the colloidal particles are driven to the meniscus via the evaporation of a solvent or matrix precursor solution where they close-pack to form a face-centered cubic colloidal assembly. Via two-dimensional large-area crystallographic mapping, we show that the initial crystal orientation is dominated by the interaction of particles with the meniscus, resulting in the expected coalignment of the close-packed direction with the local meniscus geometry. By combining with crystal structure analysis at a single-particle level, we further reveal that, at the later stage of self-assembly, however, the colloidal crystal undergoes a gradual rotation facilitated by geometrically necessary dislocations (GNDs) and achieves a large-area uniform crystallographic orientation with the close-packed direction perpendicular to the meniscus and parallel to the growth direction. Classical slip analysis, finite element-based mechanical simulation, computational colloidal assembly modeling, and continuum theory unequivocally show that these GNDs result from the tensile stress field along the meniscus direction due to the constrained shrinkage of the colloidal crystal during drying. The generation of GNDs with specific slip systems within individual grains leads to crystallographic rotation to accommodate the mechanical stress. The mechanistic understanding reported here can be utilized to control crystallographic features of colloidal assemblies, and may provide further insights into crystallographically preferred growth in synthetic, biological, and geological crystals. article_number: e2107588118 article_processing_charge: No article_type: original author: - first_name: Ling full_name: Li, Ling last_name: Li - first_name: Carl Peter full_name: Goodrich, Carl Peter id: EB352CD2-F68A-11E9-89C5-A432E6697425 last_name: Goodrich orcid: 0000-0002-1307-5074 - first_name: Haizhao full_name: Yang, Haizhao last_name: Yang - first_name: Katherine R. full_name: Phillips, Katherine R. last_name: Phillips - first_name: Zian full_name: Jia, Zian last_name: Jia - first_name: Hongshun full_name: Chen, Hongshun last_name: Chen - first_name: Lifeng full_name: Wang, Lifeng last_name: Wang - first_name: Jinjin full_name: Zhong, Jinjin last_name: Zhong - first_name: Anhua full_name: Liu, Anhua last_name: Liu - first_name: Jianfeng full_name: Lu, Jianfeng last_name: Lu - first_name: Jianwei full_name: Shuai, Jianwei last_name: Shuai - first_name: Michael P. full_name: Brenner, Michael P. last_name: Brenner - first_name: Frans full_name: Spaepen, Frans last_name: Spaepen - first_name: Joanna full_name: Aizenberg, Joanna last_name: Aizenberg citation: ama: Li L, Goodrich CP, Yang H, et al.
