modis_GEO.py failures

Some time late in the UTC day 2021-10-10 or early in the day 2021-10-11 modis_GEO.py mysteriously stopped working (we hadn't manipulated the system in months). Here's an example of what's happening when I try to process almost any data with it: /marine-services/ocssw/scripts/modis_GEO.py --threshold...

The subscriptions get data from VIIRS/NPP, VIIRS/N20, MODISA and MODIST. All 8 subscriptions stopped returning new data between 11 and 15 UTC on 5/5/2021...

MODIST geo files?

John,

Thank you for the quick reply!

Just out of curiosity, why does MODISA get 5 minute attitude and ephemeris files while MODIST gets 2 hour ones?

MODIST geo files?

Are geo files for MODIST available for download from oceandata? If so where should I be looking?

Or does one need to make their own from the two hourly attitude and ephemeris files?

Thank you!

VIIRS-JPSS1 OCSSW commands L1A to L2

If I have an L1A file from VIIRS-JPSS1 and it's corresponding GEO file, what commands would I use in OCSSW to process it forward to an L2 file?

(Sorry about the "newbie question", I've exclusively used MODISA data with OCSSW since the demise of SeaWIFS)

Thank you!
