Hi @helpyuan, the satellite overpass feature of GCHP may very well have a bug. We do not test it and are not aware of anyone using it. We will take a look at it as we have time.
Thanks @lizziel, looking forward to your good news.
@yantosca, just a random related question here. Does SatDiagn work for GCHP or just GC-Classic only? I read the lines here: https://github.com/geoschem/geos-chem/issues/770#issuecomment-872487010. It seems get_local_time function is not yet available in GCHP.
Together with this issue, does it mean currently we do not have satellite overpassing capability within GCHP or models other than GC-Classic?
@yuanjianz: The SatDiagn and SatDiagnEdge only work for GC-Classic. All of the diagnostic capability of GCHP is handled by the MAPL History component.
I know there was interest in having the similar output in MAPL but I'm not sure where that stands. @lizziel is our MAPL guru.
@yuanjianz, the satellite overpass capability of GCHP is restricted to the output along a track. If there is a currently a bug there then we will need to fix it. This is not currently a priority for version 14.5 so it is currently not being worked on.

Hi all,
I have been using
track_file
to sample the model results recently (https://gchp.readthedocs.io/en/dev/supplement/satellite-overpass.html#output-along-a-track).# Question 1: GCHP has output the corresponding file, but there seems to be a slight issue with the latitude and longitude inside, as shown in the figure:
The above result is to set rcycle_track to True (
SpeciesSample.recycle_track: .true.
). But when I set recycle_track to.false.
(SpeciesSample.recycle_track: .false.
), meaning I don't want to reuse a track_file (if I understand correctly), it seems that no sampling was done, and the output result is shown in the figure (the time dimension is zero):So is this a bug? Or is there a problem with my track file? Here are my files: HISTORY.rc.txt trackfile_test_only_latlontime_20190701.txt
# Question 2: Following the above, when I set track_file to '
trackfile_test_only_latlontime_%y4%m2%d2.nc
' and recycle_track to.false.
, GCHP doesn't seem to be recognized. So I would like to ask if it is possible to read different track_file based on the date during a simulation process?It seems that it is not possible to upload netCDF files here. If you need my track_file, I can provide it to you through email or other ways.
