Re: Problems in updating LUTs and installing OCSSW processor

If you have another copy of python3 in /usr/local/bin/, it might be easier to point SeaDAS to use that copy of python3 by adding this line export PATH="/usr/local/bin/python3:$PATH" to your bash file. And then run: /usr/local/bin/pip3 install requests If you still want to use /Users/masud/...

Re: l2mapgen by command line

It's hard to tell if a .xml file is doing what it is supposed to do by just looking at it. If you share the gpt command line with the ifile name, I can test it for you. As we discussed in the post https://forum.earthdata.nasa.gov/viewtopic.php?t=3823#p13616, SeaDAS can not write to netCDF4-CF at the...

Re: Seadas GEO.hdf

SeaDAS processors (OCSSW) V2022.3 works best with SeaDAS 8.3.0. With V2022.3, we use the new naming convention -- https://oceancolor.gsfc.nasa.gov/docs/filenaming-convention/. For A2010283180500.L1A_LAC (MODIS AUQA L1A) modis_GEO -> AQUA_MODIS.20101010T180500.GEO.hdf (GEO) from L1A modis_L1B -> AQUA...

Re: Problems in updating LUTs and installing OCSSW processor

In SeaDAS 8.3.0 GUI, can you do SeaDAS-Toolbox -> Software & System Info and post the result here? "ModuleNotFoundError: No module named 'requests'" indicates SeaDAS can't find "requests''. It's probably due to some environment variable not setting up correctly. There are a few po...

Re: Software Tool to read the .nc file

SeaDAS can read L1A, L1B, L2, L3m MODIS AQUA files obtained from this site or created by SeaDAS processors. SeaDAS can also read most other MODIS AQUA files in .nc or .hdf format.

Question: mapgen script with MODIS L2

Re: mapgen script with MODIS L2

mapgen on an L2 file is equivalent to l2bin + l3mapgen. It seems mapgen fails doing l2bin with l2_flags as one of the products. Please try python path/SeaDAS/ocssw/bin/mapgen --ifile=path/A2020003181000.L2_LAC_OC.x.nc --ofile=path/mapgenTest_A2020003181000.L2_LAC_OC.x.nc --product=chlor_a --resoluti...

Re: how to read Remote Sensing Reflectance data at 443 & 555?

SeaDAS has a tool l3mapgen that can create a level 3 mapped file from a level 3 binned file, and SeaDAS can read the mapped file.

Here is an introduction to SeaDAS -- https://seadas.gsfc.nasa.gov/
and the help on l3mapgen -- https://seadas.gsfc.nasa.gov/help-8.3.0/processors/ProcessL3mapgen.html
