Model Ouput

Model output is available at NCCS Dataportal

Figure 1: Simulated daily surface (0-10 cm) soil moisture at 00Z on 25 September 2014 over the WLDAS domain. The inset map highlights the 1 km grid spacing of WLDAS products.


The files are organized into monthly folders with format YYYYMM/

Within each folder, daily files are contained with format

Where YYYY is the 4-digit year, MM is the two-digit month, DD is the two-digit day, HH is the two-digit hour, and mm is the two-digit minute. Times are in Coordinated Universal Time (UTC). For example, a file with the time stamp 20200910_0000 represents the 24-hour period ending at 0000 UTC on 10 September 2020.

Each netCDF file contains the variables below.

Table 2: Daily average output of the following variables is provided by WLDAS on a 0.01°x0.01° grid. Bolded fields denote that the variable is available at multiple soil levels (0-10 cm, 10-40 cm, 40-100 cm, and 100-200 cm below the surface). Variables with _f_ denote forcing data.
