The LevelEdgeDiags collection

The LevelEdgeDiags collection contains diagnostics for quantities (mostly met fields) that are defined on the vertical edges of each grid box. According to the COARDS convention, all of the data variables in a netCDF file must be defined with the same vertical dimension.

Here is a sample definition section for the LevelEdgeDiags collection. If this collection is not already present in the HISTORY.rc file in the GEOS-Chem run directory for your selected simulation, you can copy and paste this into your HISTORY.rc file and edit accordingly.

To prevent an individual field from being included in the diagnostic output, place a comment character # in front of the field name.
