Abstract
The snow cover pollution in Kyzyl in 2013-2021 is analyzed based on remote sensing data. Software scripts are created in the GEE software environment; NDSI, S3, and SCI indices are calculated. Maps of the annual average value of NDSI are constructed; the degree of contamination of the territory is determined. It is found that the areas with NDSI < 0.3 weakly changed in 2013-2021: it was minimal in 2015 and 2017 and maximal (0.68%) in 2018. The NDSI values from 0.3 to 0.45 (more than 64% of the total territory under study) prevailed from 2014 to 2017.
