Ancillary data in SeaDAS v7.5 for MODIS-Aqua processing

by rakeshs » Sat May 12, 2018 1:36 am America/New_York

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#namingconvention

And 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:
l2gen ifile=A2009155084000.L1B_LAC geofile=A2009155084000.GEO ofile=A2009155084000.L2_LAC spixl=500 epixl=1000 sline=1000 eline=2000 l2prod=nLw_vvv par=A2009155084000.L1B_LAC.anc

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

Ancillary data in SeaDAS v7.5 for MODIS-Aqua processing

by rakeshs » Mon May 14, 2018 12:47 am America/New_York

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.
Rakesh
