Hello,
I was wondering if it is possible to create some of the "miscellaneous" products in SeaDAS from Level 2 files. For example, if you have the necessary input data in a L2 or L2BIN format, could you generate products such as the Uitz or Hirata PSC data? I have some of the L2 OCCCI (ESA) files and would like to create some of the PSC products you can get using l2gen, but I was hoping to do it in SeaDAS so I didn't have to figure out how to run the C code myself.
Thanks,
Kim

If the C++ code is not too messy you could implement the algorithm in python. For the NASA OBPG NetCDF4-cf format level-2 files an example using python to add a new product is available in this forum (try a full text search for "python products.xml"). Note that some OBPG tools get metadata from the "products.xml" file so for a new product you may need to create an entry in the "products.xml" file.

Kim,
The trick is having data in the correct level 2 or level 3 bin format. Once it's in the format recognized by the OCSSW code, yes, it should be possible using l3gen
(If you have L2s, you'd need to bin them for l3gen to work) The l3gen program can produce most algorithms from bin files. There are some that cannot be produced
as they require information not available in the L3 files (e.g. geometries), but I do not think the Uitz and Hirata would fall into that category.
If you can provide an example L2 CCI product, I might be able to give you a more specific yea/nay answer.

Hello Sean,
Thanks for the suggestion. I was just thinking about this problem today and thought I should check back on the forum to see if there were any other solutions and thankfully I saw your post. It would be great if I can use SeaDAS to generate these products using the OC-CCI files.
I believe OC-CCI files are already in the same L3 bin format that SeaDAS produces and they are available here: ftp://oceancolour.org/occci-v3.1/sinusoidal/netcdf/daily/.
Thanks again for your help.

Kim,
These files are not in our bin format. They are mapped (equivalent to our SMI files). Also, while they say sinusoidal in the path (and indicated in the filenames with SIN), it seems the data are in lon/lat grid format and not a sinusoidal projection. Sorry, these are not compatible with our processing binaries.
