Table of Subproduct Diagnostics¶
Some diagnostics (e.g. cape_2d) include multiple products in its
output. These products have been broken out in to individual diagnostics
to help those utilities that are unable to work with multiple outputs.
These individual diagnostics can be requested like any other diagnostic
using wrf.getvar()
. These are summarized in the table below.
