There was a corrupted version of that file distributed recently. Try updating your LUTs.

Tommy

can you run the umask command in the shell where you are running the installer. It should be 0022, 022 or 0002.

Tommy

Can you provide a specific example? The .x. in the file name means that it is an extract and not the full original file.
Can you run the 'file' command on the downloaded file and see if it is an html file? If so, open it in a browser to see the error message.

The V2 GIBS imagery were reprocessed from March 5, forward on 7/5 so they can be picked up.
The period between launch and Mar 5 will not be included in V2.

And I passed your concerns about the magnitude of negative nFLH to the developers.

Tommy

Yes - both software versions can use the same LUTs.
There are slight differences in the L2 file format between the two tags, but the scientific results should be the same.

Tommy

Yes, there is a SeaDAS patch to address this in the works.
I don't know if it will be an update to V2024.1 or a new tag.

Tommy

Are you fully updated to V2024.1? cat SeaDAS/ocssw/share/modis/msl12_defaults.par You should see these lines: # algorithm controls # ------------------ btfile=$OCDATAROOT/modis/aqua/cal/bt_modisa.hdf sstcoeffile=$OCDATAROOT/modis/aqua/cal/modis-aqua_sst_coeffcients_v6.5.nc sst4coeffile=$OCDATAROOT/m...

the differences are in the LUTs: SeaDAS/ocssw/var/modisa/cal/OPER/ MYD02_Emissive_LUTs.V6.2.1.97_OC_v3.1.hdf MYD02_QA_LUTs.V6.2.1.97_OC_v3.1.hdf MYD02_Reflective_LUTs.V6.2.1.97_OC_v3.1.hdf SeaDAS/ocssw/var/modisa/xcal/OPER/ xcal_modisa_axc_oc_v3.1d_412.hdf xcal_modisa_axc_oc_v3.1d_443.hdf xcal_modis...

Check the existence of /ocssw/var/viirsn/polar_wander.ascii in your SeaDAS installation.
