Description of your issue or question

I am running GCClassic version 14.2.0. My simulation (beginning 2019-01-01) saving monthly SpeciesConc output is running with no errors. The SpeciesConc files for January and February look normal, but the March and April output are empty (time is 0 as shown in the screenshot below). I've attached the SpeciesConc netCDF for March as well as my config files below.

I think my issue with the SpeciesConc file saying Time = 0 is solved. After waiting a while, I viewed the file again and it now has data. Although the GC.log file says that the simulation is currently on the month of June, the SpeciesConc file GEOSChem.SpeciesConc.20190501_0000z.nc4 is still 0 but the April one is now normal. It seems that the May file is still being written to even though the simulation is already on June. Is this a normal thing and I just didn't realize it before? I've never ran a monthly averaged simulation, only daily averages, so I haven't encountered this before.

I think the netCDF file isn't flushed until it's written. We may have put a fix in but I'd have to doublecheck.

There was an issue created a while back about the diagnostics not being fully written until the end of the next diagnostic period. #1464

The issue was closed since a fix went into 14.0.2. If that fix isn't working we should reopen.

Closing this issue, as the discussion has now moved to #2094 and corresponding draft PR #2096.
