White aerosol extrapolation (aer_opt=0) yields higher Rrs than no aerosol (aer_opt=-99)

Thank you Sean! Hope the bug can be squashed easily. For the moment I won't be testing these options, then.

Regards, Juan

White aerosol extrapolation (aer_opt=0) yields higher Rrs than no aerosol (aer_opt=-99)

Hi!I have been checking different SeaDAS atmospheric corrections in Rio de la Plata in multiple images and am consistently seeing higher Rrs values from white aerosol extrapolation (aer_opt=0, having set far SWIR band ~2200 nm as extrapolation band) than the correspondent Rrs values retrieved in the...

Error! Cannot find GEO file None.

Thanks!! It was solved after I re-ran the install_ocssw.py script.Regarding the fact that the l2 files weren't generated, this had to do with an error I hadn't had before when running l2gen:/path_to_seadas/bin/l2gen: libgfortran.so.3: cannot open shared object file: No such file or directory...

OLCI Vicarious Calibration Coefficients

OK, thanks. This means I'll have to wait till the transition period ends? Or is there something I can update/change for it to work?
I've retried today and it still throws the same error.

Thanks!

OLCI Vicarious Calibration Coefficients

Hi,I'm processing OLCI L1B data to obtain Rayleigh-corrected reflectance (via l2prod=rhos_nnn). My question is: are the vicarious calibration gains reported at https://www.eumetsat.int/website/wcm/idc/idcplg?IdcService=GET_FILE&dDocName=PDF_S3A_PN_OLCI_L2&RevisionSelectionMethod=LatestRe...

Using l2gen for VIIRS scene: numElemens is less than one

Hi there,I'm for the first time trying to process a VIIRS scene (I'm using GUI for the moment). I've went through L1A + GEO -> L1B (already added the correct "terrain_path" and the "dem" folder); but now I'm stack with L2GEN, which gives me back "execution ex...
