英文摘要	In the paper we present and discuss results of the radio-echo sounding and ice thickness modeling of Sary-Tor Glacier (Ak-Shyirak massif, Inner Tian Shan). Ability for correct assessment of regional glacier volume in Tian Shan is limited due to the small amount of direct ice thickness measurement data. Ca. 17 km of ice thickness measurements tracks were done on 18-20 May, 2013 using monopulse VIRL-6 GPR with central frequency 20 MHz. Maximum measured ice thickness was 159 m, whereas average thickness was 51 m. Detailed ice thickness and bedrock topography maps were compiled for Sary-Tor. Glacier volume was defined as (0,126 ± 0,001) km3. In addition ice volume was calculated using the Glab-Top model calibrated by direct data and volume-area scaling. Both approaches could be used to determine ice volume of Sary-Tor Glacier with high accuracy. The Sary-Tor Glacier area shrinkage rate in 2003-2012 slightly decreased compared to 1977-2003.
