SGD-SM 2.0

To overcome the disadvantages of previous SGD-SM 1.0, we develop an improved seamless global daily soil moisture (SGD-SM 2.0) dataset for the years 2002-2022. The main improvements and contributions of SGD-SM 2.0 are listed as follows:

• Compared with SGD-SM 1.0 (from 2013 to 2019), the application scope of SGD-SM 2.0 can be enlarged from 2002 to 2022.
• SGD-SM 2.0 assimilates auxiliary precipitation information, to consider the sudden extreme weather condition.
• SGD-SM 2.0 develops an integrated LSTM-CNN to fill the gaps and missing regions in global daily products.

More Descriptions:

• This is An improved seamless global daily soil moisture long-term (2002-2022) dataset.
• These daily products include 7115 global soil moisture NetCDF4 files (Both original and reconstructed data), starting from Jun 23, 2002 to Feb 05, 2022.
