A daily, 0.01° Snow water equivalent dataset for Tibetan Plateau (2000-2018)


Funded by the National Key R&D Program "Observation and Inversion of Key Parameters of Cryosphere and Polar Environmental Changes", "Multi-scale Observation and Data Product Development of Key Cryosphere Parameters", Changes and impacts of glaciers, snow cover and permafrost and how to deal with them (Grant NO.2019QZKK0201), and Pan-tertiary environmental change and the construction of green silk road (Grant NO.XDA20000000), the research group of Zhang Yinsheng, Institute of Qinghai-Tibet Plateau, Chinese Academy of Sciences developed downscaled snow water equivalent products in the Qinghai-Tibet Plateau. The sub-pixel space-time decomposition algorithm was used to downscale the 0.05° daily snow depth data set (2000-2018) over the Qinghai-Tibet Plateau. And the snow depth depletion model was used to supplement the estimation of the snow depth value in the shallow snow area that cannot be detected by passive microwave remote sensing. Finally, based on the snow density grid data, the snow depth data is converted into snow water equivalent data.


File naming and required software

The product information details of the Qinghai-Tibet Plateau Snow Water Equivalent Downscaling Dataset (2000-2018) are as follows. The projection is latitude and longitude, the spatial resolution is 0.01 degrees (about 1 km), and the time range is from September 1, 2000 to September 1, 2018, time resolution is daily. It is a Tif format file. The naming rule is: YYYYDDD.tif, where YYYY represents the year, ddd stands for Julian Day (001-365). Snow Water Equivalent (SWE), unit: centimeter (cm).
