Sentinel 3 OLCI in SeaDAS

[rinokeros]

Dear all,
Is OBPG ancillary still supported for Sentinel-3 OLCI in SeaDAS?

I am experiencing an issue with getanc.py when processing Sentinel-3 OLCI data in SeaDAS (V2023.3).
getanc.py S3B_OL_1_ERR____20210728T111447_20210728T115904_20240518T085009_2657_055_137______MAR_R_NT_004.SEN3/xfdumanifest.xml --ancdir=/oc10/data/Meteorological -v

I verified the following:

Authentication is correctly configured via .netrc (Earthdata login works, no errors).

The command runs correctly with -v, and the database used is:
/oc01/software/seadas-V2023.3/ocssw/var/log/ancillary_data.db

I have a complete local archive of MERRA2 meteorological data (MET/AER/PROFILE) organized by year/day:
/oc10/data/Meteorological/YYYY/DDD/

Running with --disable-download or --refreshDB does not change the result.

The OBPG request always returns 0.00 MB.

thank you in advance,
Alexandra

Thanks for reporting the issue. We are investigating it, and will get back to you.

Yes, I have encountered the same issue. SeaWiFS also returned the same error, while MODIS-Aqua worked normally.

Dear Support,
for a while now I've also been experiencing the same problem with getanc no longer returning the proper ancillary information for Sentinel-3, just referring to non optimal MET, OZONE ... files and generating an empty file.
Thanks for any help,
Best, F.
