A seamless global daily (SGD) AMSR2 soil moisture long-term (2013-2019) dataset is generated through the proposed model. This daily products include 2553 global soil moisture NetCDF4 files, starting from Jan 01, 2013 to Dec 31, 2019 (about 20GB memory after uncompressing the zip file).

To further validate the effectiveness of these productions, three verification ways are employed as follow: 1) In-situ validation; 2) Time-series validation; And 3) simulated missing regions validation. More validation results can be viewed at SGD-SM.

This soil moisture dataset is comprised of netCDF4 (*.nc) files. Therefore, users need to install netCDF4 toolkit before reading the data:
pip install netCDF4
pip install numpy
It should be noted that the original and reconstructed soil moisture data are both recorded in a NC file. User can read the original data, reconstructed data, and mask data as follows (more details can be viewed in Example.py):
Data = nc.Dataset(NC_file_position)
Ori_data = Data.variables['original_sm_c1']
Rec_data = Data.variables['reconstructed_sm_c1']
Ori = Ori_data[0:720, 0:1440]
Rec = Rec_data[0:720, 0:1440]
Mask_ori = np.ma.getmask(Ori)
Users can visualize *.nc format file through Panoply software. Before visualizing, you must install Java SE Development Kit.
