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 Table 20.
