As this thread shows, writing software to work with binned data is a nontrivial project. You will need SeaDAS to validate any new implementation, so most people just use tools available in SeaDAS.

A couple notes that may help sort out problems with l2gen: The benchmark script is useful as a reference and uses a small data set that is easy for others to obtain. If you get a netcdf output file, it should include lots of detail including the l2gen command line. This has been useful when debuggin...

[...] I read through the white paper but still couldn't understand how bins are tranlated [SIC] into lat/lon locations. [...] It can be a bit tricky to reproduce the integer number of bins for a given latitude band. In the distant past I encountered differences moving to Intel (i386?) from SGI IRIX...

Sorry you had health problems. Thanks for the follow-up and hope your OCSSW work goes smoothly.

The OCSSW software should work with just a base Python installation. Some distributions include base packages for older python versions. After installion an older python version (say 3.8) you should have '/usr/bin/python3.8'. The OCSSW programs look for python3 in the directories listed in the "...

Seems like this line actually worked without uninstalling seadas. I have got the processing started. source $OCSSWROOT/OCSSW_bash.env . Thanks to you (and one of my friends). But can you kindly explain why this line was needed. [Note: added code </> formatting] Before retiring I worked in a group t...

Is there a way to manually install the processors or fix the issue within SeaDas? Thank you! https://seadas.gsfc.nasa.gov/downloads/ has a section for "Manual Installation". If you have not used Linux command-line tools before, you will find it helpful to spend a few hours with a basic in...

Most linux distros allow you to install older python versions in order to run software developed before the current version was released. There is also Anaconda Python that has older versions. You can create a Python "environment" for the older version and run install_ocssw and the OCSSW s...

I have encountered several types of corruption with downloaded files. These days, many "enterprise" sites have malware filters. Some filters refuse to deal with NASA OBDAAC files as "unsupported file type", other flag files "at random" when they happen to have a byte se...

Good news, but the link has .com instead of .gov, which gets you to a parkingcrew.net site. Firefox detected a potential security threat and did not continue to seadas.gsfc.nasa.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details....
