SGLI L1B processing using l2gen

[atsushim]

Hi, I've found that the latest l2gen (updated on March 25, 2024) for a GCOM-C/SGLI L1B scene produces a L2 file (without an error) but no valid pixels included (e.g., GC1SG1_201909061954P42508_1BSG_VNRDQ_2000.h5). I've checked that for several other scenes that I know have several valid pixels verified with a different processor (e.g. OC-SMART) but with no success. A similar result was obtained using GUI based processing as well. Below is a par file as a test. Any clue?

# PRIMARY INPUT OUTPUT FIELDS
ifile=/media/atsushimatsuoka/am18tb1/Satdata/test/GC1SG1_201909061954P42508_1BSG_VNRDQ_2000.h5
ofile=/media/atsushimatsuoka/am18tb1/Satdata/test/GC1_SGLI.20190906T195422.L2.OC.nc

# SUITE
suite=OC

# ANCILLARY INPUTS Default = climatology (select 'Get Ancillary' to download ancillary files)

I'm using SeaDAS v8.2.0 installed on a ubuntu 22.04 LTS server (AMD® Ryzen threadripper 3960x 24-core processor × 48 with 256 GB memory). The ocssw is installed in the SeaDAS folder. All modules, LUTs, etc have been updated a week ago.

Thanks,
Atsushi

Hi,
The issue was solved by placing the corresponding IRS files in the same directory where VNR files are located.
Thanks,
