%X This dataset is prepared based on the day-by-day cloud-free product of 500m snow area in China from 2000 to 2019, and the 2000-2020 MODIS China snow phenology dataset is prepared, including three directories, with the directory naming rule of 2000-2020 China XXXX dataset, in which XXXX denotes the number of days of snow accumulation, the first day of accumulation, and the last day of accumulation of the snow phenology parameter; and sub The file naming rule is NIEER_MODIS_TTT_500m_YYYYY-YYYY.tif, in which TTT represents different snow cover parameters, and YYYYY-YYYY represents hydrological year, such as NIEER_MODIS_SCD_5000m_2001-2002.tif, with a spatial resolution of 500m and a temporal resolution of 1 year. year.Using the day-by-day cloud-free product of 500m snow cover area in China from 2000-2019 provided by the Center, according to the corresponding definitions of each parameter of snow cover climate, snow cover days (Snowcoverdays,SCD), snow cover first days (Startofsnowcover,SCS), snow cover last days (Meltofsnowcoverdays,SCM). The MODIS snow cover data set for China from 2000 to 2020 was prepared.The dataset was divided into three catalogs according to the different parameters, and the accuracy was verified by ground station data. This dataset is intended to provide basic data for the in-depth study and accurate analysis of snow cover, animal protection, climate prediction, agricultural water resource utilization, flooding, snowstorm warning and other fields.
