Dataset of daily snow water equivalent product from 1980 to 2020 over China
Listed in ScienceDB
The reliable knowledge of seasonal snow volume and its trend is very important to understand Earth’s climate system.
Description
This work presents a 40-yr (1980-2020) daily snow water equivalent product with a linear unmixing method through passive microwave radiometer data including the Scanning Multichannel Microwave Radiometer (SMMR), the Special Sensor Microwave/Imager (SSM/I) and Special Sensor Microwave Imager Sounder (SSMIS) over China.
The unbiased root mean square error (unRMSE) of snow depth is about 5-7cm, corresponding to 10-15 mm for the snow water equivalent (SWE), when compared with ground measurements of station snow depth and field snow course data.
