Re: Unable to view contents of L3 DAY CyAN NetCDFs

SeaDAS does not provide a reader for L3b files. You can use l3mapgen to create L3m files from L3b, which SeaDAS can read -- https://seadas.gsfc.nasa.gov/help-8.4.0/processors/ProcessL3mapgen.html

Re: OCSSW satellite validation matchup tools: val_extract failed

Thanks, Anna for sharing the content of matchup_entries.sb. I did replicate the error. It seems val_extract got called, but returned with error, and the error message was not helpful.

We are investigating the issue.

BTW, can you do seadas_info and share the result here?

I can download AQUA_MODIS.20110520T132501.L2.OC.nc from our site. If your seabass file is downloadable, you can share the link so I can download the file. Otherwise, you can replace the filename matchup_entries.sb with matchup_entries.txt, and share the file here.

Re: Cloud cover or similar data - Modis Aqua

I noticed that you are still using SeaDAS 7.5.3. Maybe you could try 8.4.1, which has almost all the features of 7.5.3, plus a lot more?

Question: Retrieving IOPs (aphy, bbp, ..) in SeaDAS l2gen
Replies: 1

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
