Snow cover melting can indicate various specifics of the given region, both of natural and anthropogenic origin. In the year 2018 snow melting in the Moscow Region went on quite fast under the conditions of mostly cloud-free weather in the region. This, along with absence of precipitation and snow, provided a possibility to obtain data from various Earth observation systems, most notably from the Landsat-8 satellite, and analyze the specifics of snow cover melting in different areas of the Moscow Region. The data obtained shows snow cover early melting zones in the vicinity of main roads and inhabited areas clearly. Such zones are usually associated with anthropogenic pollution and the so-called «heat islands» (increased temperature areas) observed in urban and industrial areas. Along with such zones the data analysis revealed an approx. 15 000 ha early melting zone in the flood plain of the Yakhroma River in Dmitrov District. Thorough analysis of the MODIS instrument data showed that melting in this area in the spring of 2018 began approximately four days earlier than in the surrounding areas. The area observed mainly consists of farmlands and there are no inhabited areas or industrial pollution sources there, so early snow melting here was of different origin. Data analysis for years 2013–2018 have shown that early snow melting is regular in this area. The proposed report gives the area observations for the year 2018 and observation examples for the years 2014 and 2016.
Keywords: snow cover, snow cover melting anomalies, Earth observation satellite systems, Earth remote sensing
