MODIS daily cloud-free snow cover area product for Sanjiangyuan from 2000 to 2019

MODIS daily cloud-free snow cover area product for Sanjiangyuan from 2000 to 2019

The dataset was produced based on MODIS data. Parameters and algorithm were revised to be suitable for the land cover type in the Three-River-Source Regions. By using the Markov de-cloud algorithm, SSM/I snow water equivalent data was fused to the result. Finally, high accuracy daily de-cloud snow cover data was produced. The data value is 0(no snow) or 1(snow). The spatial resolution is 500m, the time period is from 2000-2-24 to 2019-12-31.

Data format is geotiff, Arcmap or python+GDAL were recommended to open and process the data.
