Tendency Subset
===============

| **DOI:** https://doi.org/10.5439/1905837
| **File type abbreviation:** ``tend``

The tendency subset category contains variables extracted from the raw wrfout files related to process-level tendencies, such as from the microphysics parameterization.
The data are on the raw model levels listed in :numref:`TableSubsetLevels`.
