| Summary: | <!--!introduction!--> Global warming and surface albedo reduction by black carbon (BC) in glacier jointly accelerated glacier melting, but their respective contributions remain unclear. This study developed a dynamic deposition model of light absorbing particles (LAPs), which coupled with a surface energy and mass balance model. Based on the coupled model, we further assessed atmospheric deposited BC effect on glacier melting for a period of September 2011 – August 2012 on the Laohugou glacier No. 12 in the western Qilian Mountains. It was found that BC in glacier surface caused 13.1% of annual glacier-wide melting, of which atmospheric direct deposited BC reduced albedo with 0.02 and accounted for 9.1% of glacier melting. The air temperature during recent two decades has increased by 1.5 ℃ relative to that during 1950s, which accounted for 51.9% of current glacier melt. Meanwhile, based on the BC emission increased by 4.6 times compared to the early Industrial Evolution recorded in an ice core, the ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
