%X This data set is the daily snow depth data of the Northern Hemisphere from 2001 to 2010, covering the range of 0-86 ° n, 180 ° w-180 ° e. the data set combines the snow process model and snow microwave radiation transmission model, absorbs the ground observation station data to extract the snow depth, introduces the forest coverage factor to reduce the impact of forest on snow depth retrieval, and uses Ensemble Kalman filter method to synthesize The results show that the parameters of snow cover are optimized by microwave brightness temperature and simulated brightness temperature; the influence of forest is reduced by forest coverage in forest area, and the snow depth data set in northern hemisphere is obtained with spatial resolution of 0.250 * 0.250.
