Thanks for reporting the issue. It's fixed. You should get MERRA ancillary files -- $ ocssw_runner --ocsswroot ~/ocssw getanc S3A_OL_1_EFR____20210112T010238_20210112T010538_20210113T043433_0179_067_159_4140_LN1_O_NT_002.SEN3/xfdumanifest.xml “------ bottom of file .profile” Running debug binaries.....

The instructions here https://oceancolor.gsfc.nasa.gov/docs/ocssw/index.html are obsolete. Please compile ocssw following the instructions here https://seadas.gsfc.nasa.gov/build_ocssw/

getanc should work now. Please try again.

modis_GEO failed because it did not get the corresponding att/eph files. Things are back to normal now. Please try again.

If you are able to install and open SeaDAS, you can ignore the warning.

We’re having some database related issues. In fact, getanc and modis_atteph are not working for any dates at this moment. We'll let you know when we have an update.

I assume you are using OCSSW V2021.2. If you want to do l2gen with ancillary files, you can click "Get Ancillary" on the main tab on l2gen GUI. I successfully did l2gen on S2003243191524.L1A_MLAC with the following ancillary files icefile=/Users/*/ocssw-V2021.2/var/anc/2003/243/N2003243_SS...

We are sorry to say that no tags of OCSSW currently works with l2gen on Landsat 9 L1 B files. R2022.5 and T2022.14 might have the new code to process Landsat 9, but it cannot read the oli tables. I assume R2022.3 works for both collection 1 and 2 of Landsat 8. However, we are using the same atmosphe...

I tried EN1_MDSI_MER_RR__1P_20020727T093846_20020727T102241_002123_0065_20180523T151615_0100. It did not return MERRA MET files. Unfortunately, V2022.0 did not recognize EN1_MDSI_MER_RR__1P* as a MERIS file.

It's fixed and will be in the next V tag. R2022.4 and up has the fix. The latest is R2022.7

What tag of OCSSW are you using? This is what V2022.0 returns -- $ getanc /Users/*/Scenes/MERIS/forum/EN1_MDSI_MER_FRS_1P_20110303T145459_20110303T150439_047094_0097_20171225T172751_0100.SEN3/xfdumanifest.xml Running debug binaries... /Users/*/ocssw/bin ancillary_data.db MERIS icefile=/Users/*/ocssw...
