Daily 5-km Gap-free AVHRR snow cover extent product over China (1981-2019)
Based on AVHRR-CDR SR products, a daily cloud-free snow cover extent dataset with a spatial resolution of 5 km from 1981 to 2019 was prepared by using decision tree classification method. Each HDF4 file contains 18 data elements, including data value, data start date, longitude and latitude, etc. At the same time, to quickly preview the snow distribution, the daily file contains the snow area thumbnail, which is stored in JPG format. This data set will be continuously supplemented and improved according to the real-time satellite remote sensing data and algorithm update (up to may 2019), and will be fully open and shared.
The data is stored in HDF format;
The file name is: NIEER_ GF AVHRR SCE_ YYMMDD_ DAILY_ 5km_ V01, where YY represents the year, mm represents the month and DD represents the date;
Reading mode: any software supporting HDF format reading, such as HDF explorer, envi, ArcGIS, etc
