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."}],"oa":1,"status":"public","_id":"12589","volume":15,"publication_status":"published","quality_controlled":"1","issue":"2","type":"journal_article","article_processing_charge":"No","title":"Distributed summer air temperatures across mountain glaciers in the south-east Tibetan Plateau: Temperature sensitivity and comparison with existing glacier datasets","date_published":"2021-02-09T00:00:00Z","date_created":"2023-02-20T08:11:56Z","scopus_import":"1","author":[{"last_name":"Shaw","first_name":"Thomas E.","full_name":"Shaw, Thomas E."},{"last_name":"Yang","first_name":"Wei","full_name":"Yang, Wei"},{"last_name":"Ayala","first_name":"Álvaro","full_name":"Ayala, Álvaro"},{"full_name":"Bravo, Claudio","last_name":"Bravo","first_name":"Claudio"},{"full_name":"Zhao, Chuanxi","last_name":"Zhao","first_name":"Chuanxi"},{"id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","last_name":"Pellicciotti","first_name":"Francesca","full_name":"Pellicciotti, Francesca"}],"month":"02","citation":{"apa":"Shaw, T.
