Question: Retrieving IOPs (aphy, bbp, ..) in SeaDAS l2gen

Re: Retrieving IOPs (aphy, bbp, ..) in SeaDAS l2gen

You can add suite=IOP to the l2gen command as in

Code: Select all

l2gen ifile=/mnt/c/Users/Malawi/1/inputfile maskglint=true, maskland=true, iop_opt=3 ofile=/mnt/c/Users/Malawi/1/T36LXP_20221020T093755_msi.l2 suite=IOP
I think the default is iop_opt=7, but iop_opt=3 should work too

Re: L2gen output missing OLCI bands >709 nm

Use Rrs_nnn instead of Rrs_vvv as in "Kd_490 Rrs_nnn angstrom aot_865 chlor_a" for l2prod in the Selected Products tab.

Re: OCSSW satellite validation matchup tools: val_extract failed

If you are using SeaDAS 8.4.0, I believe the right command is find_matchup and make_matchup. Here are the help pages -- https://seadas.gsfc.nasa.gov/help-8.4.0/FieldMeasurements/FindMatchups.html https://seadas.gsfc.nasa.gov/help-8.4.0/FieldMeasurements/MakeMatchups.html Could you please try /Users/...
