%X This dataset is based on the 5km AVHRR day-by-day cloud-free snow accumulation area product from 1980 to 2020, and the long time series snow accumulation and climate dataset in China is prepared. The dataset is divided into three directories according to different climatological parameters, namely, the number of snow days, the first day of snow accumulation, and the last day of snow accumulation, and each directory contains 40 subfiles for hydrological year-by-year snow accumulation and climatological parameters.The naming rule of the directory is 1980-2020 China XXXX dataset, in which XXXX indicates the number of snow days, the first day of snow, and the last day of snow; and the naming rule of the subfiles is NIEER_AVHRR_TTT_5000m_YYYYY-YYYY.tif, in which TTT indicates the different snow parameters (SCD is the number of snow days, SCS is the first day of snow, SCM is the first day of snow, and SCM is the first day of snow. SCD is the number of snow days, SCS is beginning date of snow cover, and SCM is ending date of snow cover), and YYYY-YYYYY is the hydrological year.This dataset can be used to analyze the spatial and temporal changes of snowpack in China, and provide basic data for climate research, hydrological management, ecological environment, humanities and economy, and other scientific researches, engineering construction and social services.
