Quantifying the Artificial Reduction of Glacial Ice Melt in a Mountain Glacier (Urumqi Glacier No. 1, Tien Shan, China)

Artificial glacier melt reduction is gaining increasing attention because of rapid retreats and the projected acceleration future mass losses. However, quantifying effect artificial on glaciers in China has not been currently reported. Therefore, case Urumqi Glacier No.1 (eastern Tien Shan, China) used to conduct a scientific evaluation cover efficiency for between 24 June 28 August 2021. By combining two high-resolution digital elevation models derived from terrestrial laser scanning unmanned aerial vehicles, albedo, meteorological data, ablation mitigation under three different materials was assessed. The results revealed that up 32% loss preserved protected areas compared with unprotected areas. In contrast surface, nanofiber material reduced by 56%, which significantly higher than achieved geotextiles (29%). This outcome could be attributed albedo local climate factors. showed geotextiles, dirty snow, clean ice, ice. Although snow had other materials, its impact slowing minor due lower snowfall relatively high air temperature after study area. indicates efficiencies can beneficial high-mountain general, our demonstrate potential help mitigate issues related regions or lacking water resources, as well tourist attractions.
