[BUG/ISSUE] Missing metadata for various ND51 tracers

[jennyfisher]

Describe the bug

This is related to issue #260. It seems quite a lot of the various metadata fields for ND51 diagnostics were removed from gamap_mod.F and this creates problems for reading this files with IDL/GAMAP.

In my case, I've had issues with the following tracers 511 (boxheights) and 512 (pressure edges). These are not linked to the TIME-SER diagnostic info but rather the PEDGE-$ and BXHGHT-$ diagnostics. Those are no longer written to diaginfo.dat and tracerinfo.dat, and so when reading the file using GAMAP, they don't show up at all. I can temporarily "fix" the problem by copying the relevant info from an old version of tracerinfo.dat and diaginfo.dat into the new versions written by the model.

I imagine there are several other tracers in this boat.

Fix would be to re-instate the relevant code in gamap_mod.f until these diagnostics are replaced.

(FYI, I rarely use GAMAP, but it is still the easiest way to convert these files to a COARDS-compliant netcdf file. When I use the bpch_to_nc script that ships with xbpch a lot of information is missing, including the time dimension, which would require a lot of work to recreate!)

To Reproduce

Compilation commands
Follow out of the box instructions.

Run commands
In input.geos, turn on ND51 including tracers 511 and 512 (for example). Otherwise run as normal.

Expected behavior

Metadata for all possible ND51 tracers written to tracerinfo.dat and diaginfo.dat.

Error messages

None.

Required information

• GEOS-Chem version 12.8.2
• Compiler ifort 19.0.5.281
• netCDF 4.7.1
• Gadi cluster
• "out of the box" code

Input and log files to attach

I don't think these are needed in this case, but let me know if you would still like them.

Additional context

[msulprizio]

The information relevant for the timeseries diagnostics has been restored in gamap_mod.F90. See commit 11585ed. This fix will be included in 12.9.0.

In the meantime, you can use an old tracerinfo.dat and diaginfo.dat or add the missing entries to those files as a workaround as suggested in #260.
