AB  - This atlas is aimed at the farmland areas in Northeast China, including Heilongjiang Province, Jilin Province, Liaoning Province and the East Four League cities in Inner Mongolia, and uses the 25km provided by the second subject of the "Investigation on the Distribution and Characteristics of Snow Cover in China" project × The potential supply of snow water in the northeast farmland area in the winter of 2017-2020 (December to March of the next year) is calculated by using the daily snow water equivalent product with 25km resolution. Without considering the effect of evapotranspiration, the potential supply of snow water can be considered as the sum of snow water equivalent in the whole snowfall season. According to the observed snow depth data of meteorological stations in 2017-2020, the maximum snow cover on the ground in each winter is before March, and the snow gradually melts after March, but there is still snow during the period. Therefore, the potential supply of snow water can be considered as the sum of the maximum snow equivalent before March and the increased snow equivalent after March. This data set contains thematic maps and corresponding mapping data of three snow seasons from 2017 to 2020, which are fully open and shared.
