英文摘要	In the paper we present and discuss results of ground-based measurements and remote assessments of glacier albedo in the Ak-Shyirak massif (Inner Tien Shan). Tendencies of decreasing albedo are typical for many glacierized mountain regions and lead to accelerated glacier downwasting. In the Ak-Shyirak massif the situation is complicated by technogenic dust pollution, whose contribution to albedo changes was unknown. Ground-based albedo measurements were carried out across 11 glaciers during summers 2015 and 2016 using Sp Lite 2 Kipp&Zonen albedometer. On the basis of ground albedo measurements of two glaciers we developed a model to correct albedo values obtained from satellite imagery. 27 images from Landsat satellites were selected to assess glacier albedo in the Ak-Shyirak massif by weather conditions. In comparison to some other mountain regions we do not observe a decrease of glacier albedo in the Ak-Shyirak massif since 1990s. Glacier albedo in the Ak-Shyirak massif is driven by environmental factors, mostly by weather conditions prior to satellite survey, especially snowfalls, and elevation driving the snow melting. Technogenic impact (mechanical disturbance of glaciers within the Kumtor mine) is detected only locally, while technogenic dust on the background of natural dust is not traceable, with imagery from Landsat satellites, on glaciers across the Ak-Shyirak massif. © 2019 Academic Publishing House Geo.
