[jstum]

Hello,
modis_GEO.py fails for MODIS/Aqua L1 granules on day 336 :

modis_GEO.py A2020336125500.L1A_LAC -o A2020336125500.GEO -a PM1EPHND_NRT.A2020336.1255.061 -A PM1ATTNR_NRT.A2020336.1300.061 -e PM1EPHND_NRT.A2020336.1255.061 -E PM1EPHND_NRT.A2020336.1300.061

ERROR: MODIS geolocation processing failed.

It seems there is the same kind of error on MODIS/Terra (see a previous post)

Are you going to reprocess the attitude and ephemeris files ?

Thank you
Jacques
