Ancillary data in SeaDAS v7.5 for MODIS-Aqua processing
Posted: Sat May 12, 2018 1:36 am America/New_York
by rakeshs
Hello,
I've installed SeaDAS v7.5 and facing the following issue.
I'm getting this error in l2gen
-E- $OCSSWROOT/ocssw-src/src/l2gen/ice_mask.c line 223: File, "", doesn't follow naming convention described at http://nsidc.org/data/docs/daac/nsidc0051_gsfc_seaice.gd.html#namingconventionAnd if I don't give ancillary data it ends up like
"Skipping ancillary retrieval for scan #### - entire scan invalid"Can anybody help me with this?
Thanks,
Rakesh

Just using some random data files, I've not been able to reproduce this. What was your input file?

Hello Melliott,
Here is the command:

Here is the output:
Input file A2009155084000.L1B_LAC is MODIS Aqua Level-1B HDF-EOS product.

Hello,
Today I tried running l2gen again and it is running fine now.
I don't know how the issue got resolved but it has.
Thanks a lot for listening.
