MODIS geolocation processing failed

[jianke]

Recently when I tried to use SeaDAS's modis_GEO.py file to process the Aqua "*.L1A_LAC" data in order to get the GEO file, I always get this error message,

"Percent valid data (0.00) is less than threshold (95.00)
ERROR: MODIS geolocation processing failed."

I have randomly tried many files and all got the same errors. Could someone please help?

Thanks,

Please let us know what version of SeaDAS you are using? SeaDAS 7 or 8?

Please also let us know the name of one of modis L1A files that modis_GEO.py failed on.

Here is another post regarding modis_GEO. The user has issues with modis L1A files on 2/11/2020. viewtopic.php?p=10894&sid=540d9a79990fb3ebe4220a509c55aec7#p10894

The SeaDAS version I am using is 7.5. Here are the L1A files I have tried, and they all failed with the same error.

A20221071710.L1A_LAC
A20221081755.L1A_LAC
A20221091700.L1A_LAC
A20221101740.L1A_LAC
A20221111825.L1A_LAC

Try to run

Code: Select all

update_luts.py

and then try modis_GEO.py again

Great, it works now.
