[BUG/ISSUE] Invalid time stamp in GC-Classic restart file #43

Closed StrangeFrog closed 2 years ago

Report a technical issue for GEOS-Chem on the AWS cloud

HEMCO ERROR: Cannot find field with valid time stamp

Hello, this picture shows the problem I encountered. image

This picture shows the list of files in my current folder. image

This picture shows the modified content of the input。geo file. image

To Reproduce

I tried to search this question in Google browser and got some reference answers（http://wiki.seas.harvard.edu/geos-chem/index.php/GEOS-Chem_restart_files#Restart_files_in_GEOS-Chem_12）. Unfortunately, I still haven't solved this problem.

Hope to get help, thank you.

It looks like your simulation starts on May 1 but your restart file is for April 1. The restart file date must match your simulation start date. Did you try to fix this problem using the instructions at the wiki page you linked to and it did not work?

Thank you for your reply. I have made two more attempts to solve the problem according to your message.

  1. I adjusted the simulation time, and I downloaded the data again. But this problem has not been solved.

  1. For wiki link (http://wiki.seas.harvard.edu/geos-chem/index.php/GEOS-Chem_restart_files#Restart_files_in_GEOS-Chem_12), i have captured these information in web as pictures. Screenshot from 2021-12-14 10-05-24

Then， I tried to change Restart.fields: '''SpeciesRst?ALL? to Restart.fields: '''SPC?ALL? . And i have a error again.

It's crazy that this problem happens again and again. I can't understand why I should check hemco_ Config. rc error image

Hi @StrangeFrog, what version are you using? It would also be helpful if you upload your config and log files by adding extension '.txt' and dragging and dropping into the comment box. Finally, how did you generate your restart file?

yantosca commented 2 years ago

@StrangeFrog, I'd recommend starting fresh with a more recent version (like 13.3.1), so that you get a good restart file.

Thank you very much. I have solved this problem.

lizziel commented 2 years ago

Glad you were able to solve it. Could you follow-up with a post here on what ended up working to fix the issue? This may help other users in the future who experience the same problem.

  1. The first step to solve this problem is to determine that there is a match between the restart file and the simulation start time.

  2. Check the internal time of restart file, $ ncdump -h GEOSChem.SpeciesConc.20190701_0000z.nc4

    netcdf GEOSChem.SpeciesConc.20190701_0000z { dimensions: time = UNLIMITED ; // (1 currently) lev = 72 ; ilev = 73 ; lat = 46 ; lon = 72 ; variables: double time(time) ; time:long_name = "Time" ; time:units = "minutes since 2019-07-01 00:00:00 UTC" ; time:calendar = "gregorian" ; time:axis = "T" ; ...

Make sure “ time:units = minutes since 2019-07-01 00:00:00 UTC” and the file name and time are consistent.

If the time is inconsistent, please modify it（https://github.com/geoschem/geos-chem/issues/712）.
