The soil moisture dataset of China based on microwave data assimilation (2002-2011)

The soil moisture data set of China based on microwave data assimilation contains three layers of soil moisture data (0-5 cm, 5-20 cm, and 20-100 cm) from 2002 to 2011. The data adopted the automatically calibrating parameters land data assimilation system (ITPLDAS) developed by Yang et al. (2007), the land surface process model SiB2 was then driven by the high spatiotemporal resolution ground meteorological element data set (ITP-forcing data set) in China, the brightness temperature observed by the AMSR-E satellite was assimilated, and, finally, three layers of soil moisture data were obtained. Soil moisture content accuracy: ± 5% VWC (evaluation accuracy of Naqu and Maqu on the Tibetan Plateau).

Data file name:

Description of data content variables:

The file mainly consists of five variables: lon, lat, lev, time and www;

www (time, lev, lat, and lon) is the soil moisture content (missing value: -999.0), where lon, lat, lev, and time are the four dimensions of longitude, latitude, depth and time, respectively;

Variable unit description:

Soil water volume content (www): m3/m3
