OCI Version 3 files

by rodbager3579 » Tue Mar 25, 2025 11:33 am America/New_York

Hello

I'm trying to open the Version 3 OCI files from PACE, the problem is that SeaDAS doesn't open them.
Do I need to update to the latest version of Seadas, or what can you suggest I do to fix this?

You are right that SeaDAS 9.1.0 cannot read OCI L1B V3 files. We expect the next release of SeaDAS 9.2.0 can.

I really appreciate your response.
Do you know of any other ways to process OCI Level 1-b data?

SeaDAS *can* load the OCI V3 L1B data, but you need to use Import->Generic Formats->NetCDF-CF
It won't have the niceties that the product-specific reader would have, but it does work.
