Recurring problem seen when executing version 1.0 of: cspp-geo-gglm.sh on GOES-18 GLM data?

[jpnIII]

Hi all -- I am not sure where this note should be sent, so I am trying this avenue...

For quite a while now (a number of months), I have seen an error pop up from time to time when processing GOES-18 GLM data via the 1.0 release of cspp-geo-gglm.sh. FYI, I have been running cspp-geo-gglm.sh on GOES-18 GLM data since January 2023. If I recall correctly, this error was much more rare back in 2023. In the last couple of months, however, the error has been popping up numerous times each day. The error does not occur when processing GOES-16 GLM data.

If you look below, you will see some output from processing GOES-18 data from 18Feb2024. The first chunk of output shows "good" processing when processing the 1309 UTC imagery. At the bottom, you will see some error output that occurred when processing the 1310 UTC imagery.

Fortunately, the vast majority of the time cspp-geo-gglm.sh still works correctly.

Thank you for your help with this one!

Sincerely,

Jim
