Surface Subset
==============

| **DOI:** https://doi.org/10.5439/1905835
| **File type abbreviation:** ``sfc``

The surface subset category contains variables extracted from the raw wrfout files related to the surface layer and soil state.
The 3-D variables in this file are on the soil model levels.
