Rayleigh-corrected reflectance
Hi all, I want to obtain rayleigh-corrected reflectance of GOCI by SeaDAS, and I wonder whether rhos_vvv in the output file corresponds to the rayleigh-corrected reflectance results I want. Since the attributes annotation of rhos_vvv is "Surface reflectance", it confused me a lot. Thanks a...

Question about Lt results of Landsat8 OLI
Dear all, Hi! I used SeaDAS(v8.0) l2gen (oli module) to process with Landsat8 Collection1 data and obtained Lt data successfully.

Re: How to process Landsat8 Collection2 L1 data with SeaDAS
Thanks Sean. Now I successfully produced L2 data from Collection1 L1 data. However, I found there exists a lot of negative Rrs values, especially Rrs(655). During AC process, variables are all set by default, and ancillary data has been caught first. Is it the wrong variable setting or something els...

Hi,
Thanks for your reply. Follows is the output shown in System Info.
I am not sure what it stands for? Since it works well when processing Landsat8 Collection1 L1 data.
Hope to hear from you soon and thanks a lot.

Hi! Thanks a lot for your kindly help. I use zsh on macOS 10.13.6 and SeaDAS 8 (replace of v7.5.3) works well now. However a new problem comes up when I use getanc.py to catch ancillary data file: "command not found: getanc.py", it may regards to upgrade of SeaDAS but I am not clear how to...

Question about OCSSW_bash.env
Hi,
I met a problem when I try to source $OCSSWROOT/OCSSW_bash.env: "/Applications/seadas-7.5.3/ocssw/OCSSW_bash.env:136: = not found". I am not sure what's going on since it worked well before.
How should I solve this problem? THANKS.
