Processing MODIS L1A to L2 with partial ephemeris available
Posted: Wed Mar 01, 2023 11:30 am America/New_York
Good evening,
I have seen that MODIS L1A are back, but it is not yet the case for ephemeris and attitude. So far, I used as input of modis_GEO PM1ATTNR_NRT files and PM1EPHND_NRT files available every 5 mn. I see that only PM1ATTNR files (every 2 hours) and only one PM1EPHND file at 12h00 are available. I launched modis_GEO with these files and it worked well, but my question is : is the geolocation accurate enough (over ocean) ?
Another associated question : when will the 5-mn attitude and ephemeris files be available again ?
Thank you !
Best regards,
Jacques
