issue in MSI L2gen proceesing

[tlin2_cuny.edu]

Hi all,
I encountered an issue when processing MSI L1c files with SeaDas L2gen. It did not report an error but did not continue to process after getting the ancillary files. My l2gen version is msl12 9.6.0-V2022.2 and seadas version is 8.3.10.

Does anyone has idea about it? Thanks a lot.

The format of the MSI data changed since processing was implemented for it in l2gen. We have not had the time to assess the changes to see what would be needed to be changed in the code to allow l2gen to work with the new format. It may be quite some time before we are able to do so.

Thanks for yoru reply. So L2gen with MSI is currently unavailable, right?

[OB.DAACx - SeanBailey]

Well, if you have data in the older format, it would work
...but yes, l2gen processing for the current MSI file format is unavailable.

Older format means before 2022? Would you mind tell me what is the date of changed format? Thanks a lot!

Best,

Regarding the format change see this post.

Has the issue regarding MSI been resolved? Do I need to download a new version of OCSSW?

[OB SeaDAS - knowles]

No. The MSI processing issue for new format files has not been resolved.
