This dataset is a day-by-day snow albedo data for the land area of China, covering the time range from January 2000 to March 2020, and is raster data in HDF format. The geospatial range is 72°-142°E, 16°-56°N, and the equal latitude and longitude projection is used with a spatial resolution of 0.01°.
The dataset is based on MODIS albedo product MOD09GA, snow accumulation product MOD10A1/MYD10A1 and Global Digital Elevation Model SRTM data, and the snow accumulation albedo inversion model is developed on the basis of the ART model and produced interactively with GEE and the local end. The data elements include black sky albedo, white sky albedo, solar zenith angle, inversion markers, and cloud markers.
MOD09GA is a reflectance data product (L2G) released by NASA's LP DAAC and is directly callable in the cloud.
MOD10A1/MYD10A1 is a snow cover data product released by the National Snow and Ice Data Center (NSIDC).
SRTM is a NASA/CGIAR release of global digital elevation data.
TModel used for inversion calculations: snow albedo inversion model developed on the basis of the ART model.
Software tools: cloud (GEE) and local (Python) interactive production, MATLAB for data format conversion, ArcPy for thumbnail generation.
Methods of error control, treatment: adding inversion case identification bands to each product.
The data quality is good.
