Hello, I understand that you are trying to do l2gen for sentinel 3 data. If you haven't read it, this page should be helpful to you: https://seadas.gsfc.nasa.gov/help-8.3.0/processors/ProcessL2gen.html There is also a video with an example of using l2gen (https://www.youtube.com/watch?v=Mw3hg2w3xNg)...

The code was originally from by Dr. Piotr Flatau at UCSD (https://pflatau.scrippsprofiles.ucsd.edu). So please reach out to him for attribution.

Hello. Please try again and let us know if the problem still exists.

Hi,

There is NASA standard Level-2 IOPs for sentinel-3, such as "S3A_OLCI_EFRNT.20180115T000206.L2.IOP.nc" from https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-2/S3A-OLCI/. Algorithm descriptions for NASA standard IOPs are here: https://oceancolor.gsfc.nasa.gov/atbd/giop/.

Hi Christel,

Thank you for reporting the issues. We just finished reprocessing Terra data (R2022). Can you please let me know your subscription numbers?

We recently updated the file search tool, and more updates on the website are coming.
Sorry about the confusion.

Seems you are looking for the source code. Here they are:
https://github.com/seadas/seadas-toolbox
https://oceancolor.gsfc.nasa.gov/docs/ocssw/

Those are algorithms for the products we are providing on ocean color website, which are also the product algorithms used in L2 gen. By algorithm description for SeaDAS OCSSW, what are you looking for? Different algorithms or how OCSSW works? Here is the link to the description and help page for OCS...
