Long-term snow depth dataset of China (1978-2012)


This data set provides daily snow thickness distribution data of China from October 24, 1978 to December 31, 2012, with a spatial resolution of 25km.The original data used for the inversion of the snow depth data set came from SMMR (1978-1987), SSM/I (1987-2008) and amsr-e (2002-2012) daily passive microwave bright temperature data processed by the national snow and ice data center (NSIDC).As the three sensors are mounted on different platforms, there is a certain system inconsistency in the obtained data.The time consistency of bright temperature data is improved by cross calibration of bright temperature of different sensors.Then, based on Chang algorithm, Dr. Che tao is used to carry out snow depth inversion.Refer to the data description document for specific inversion methods.


Data file naming and use method

Data for TXT format, can be opened with programs and remote sensing software.
File naming: sensor name abbreviation + year, such as SR1985 under ease-grid_rar directory represents 1985 snow depth inversion with SMMR bright temperature data
