Wish to produce some MODIS Aqua L1B files using OBDAAC (directdataaccess) L1A & GEO files. Found not all L1A files have same day Geolocation files. Such as day 2008-01-01:

Need help to get those matching Geo-___location files for L1B file processing.

Many thanks !

We have only reprocessed the GEO files for the daynight flag=1,3 so far. The GEO for night granules will be processed soon.

Thanks for the info.

Will check back to see night time geolocation files in the future.

You can still generate the night GEO files you need in SeaDAS as was done before we started putting them in the public archive.
