Question: SeaDAS 10.0 Windows fails to open GOCI L1B (NASA source)
Replies: 2

Try running the file command on the L1B file to ensure it is not compressed.

Re: Missing global ancillary data

GMAO transitioned from CF V1 to CF V2 and we had to modify our code to read the new file format.

The new code was published this morning and CF processing is caught up again.
