Re: SeaDAS 8 install_OCSSW problem with python requests

Since you are running the installer from inside the GUI, can you post the output of the SeaDAS menu item:

Re: SeaDAS 8 install_OCSSW problem with python requests

Once your .bashrc points to the new seadas8 stuff you should be fine. I am pretty sure that the OCSSW from seadas7.5.3 had troubles with python3.

Re: SeaDAS 8 install_OCSSW problem with python requests

The update_luts script uses python3. Can you run a few commands for me and send me the output?

echo $PATH
which update_luts
which python3

Re: OCSSW: Remote server is down

We need to know what version of SeaDAS you are running, what operating system you are running on and what you are trying to do.

MODIS 1640 nm band

Your picture did not come through, but if you are looking at L1 or L2 MODIS files you will see stripes due to the bowtie effect.  For MODIS at 1km you will see stripes every 10 lines, 500m at 20 lines, 250 at 40 lines.  It is worse off nadir.  See this:MODIShttps://oceancolor.gsfc.nas...

Chlorophyll concentration OCI VS Chlorophyll Concentration OCX Algorithm

The size of the OCI and OCX are both float, so they will be the same size in an L2 file.  The only way the L2 files could be a different size is if more products were put on one of the files.  You can use "ncdump -h" on the command line or look at the list of bands using SeaDAS.
