Comparison of bpch vs. netCDF diagnostic output in GEOS-Chem 12.5.0
In order to identify any potential issues with the implementation of the GEOS-Chem "History" diagnostics, we compared the bpch diagnostic output (aka "Ref") vs. the netCDF diagnostic output (aka "Dev") from the 1-month GEOS-Chem 12.5.0 benchmark. The results will inform us as we proceed to remove the bpch diagnostics from GEOS-Chem.
