Abstract：

Soil moisture is an important factor affecting energy cycle, water-carbon cycle, agricultural process, hydrometeorology and so on. The 20-m/12-d Soil Moisture Dataset covers Panzhuang Irrigation District of China (2020) was developed based on the series Sentinel-1 SAR images in 2020. A linear regression model was established between the backscattering coefficient and surface soil moisture. At the same time, the method of supporting vector machine in machine learning was used to identify and extract the farmland in Panzhuang of China. The dataset includes: (1) boundary data of Panzhuang Irrigation District; (2) soil moisture data in 31 periods of 2020. The temporal resolution is 12 d and the spatial resolution is 20 m. The dataset is archived in .shp and .tif data formats, and consists of 43 data files with data size of 5.16 GB (compressed to 4 files with 1.09 GB).Browse
