Hi Daniel,
Did you examine the subset options in V2022.1? I have a l2 file generated in V2022.1:
https://drive.google.com/file/d/1BE_D0MqYvtva9l9Yx5YEfCeWhFoMlLqU/view
which includes all inputs used in the processing.
Same configuration worked in V2021.1 but failed in V2022.1.
Regards,
Zhigang

Re: Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0
I reverted the V2021.1, it works now. I am not sure whether I wrongly set V2022.0 or this version has potential bugs.

Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0
Hi, Recently, I am confused about MODISA processing using V2022.0 OC processors. Here is an example: I set the south=30.9, north=31.09, west=82.1, east=82.3 in l2gen to process A2002274073500.L1B_LAC. But output level-2 product is in lat=<20.28, 20.29>, lon=<91.96, 91.97>. The input boundary was mis...

Re: l2gen boundary arguments not working in SeaDAS8.1
Brian, you could revert it to the previous version (V2021.1), it works well. -- Zhigang

Fortunately, it is easy to use the GPF when SNAP was installed in the same system. I will try it later

Re: how to remove bowtie for VIIRS imagery in SeaDAS
Yes, I would like to improve the appearance thourough filling those deleted pixels at the edges of scans. I processed the data using the ocssw in Ubuntu 18.04. I found that the data generated by l2gen without subset options could get beautiful image after reprojection. But the results with subset op...

how to remove bowtie for VIIRS imagery in SeaDAS
Greetings, I am processing some VIIRS data in SeaDAS with V2021.1 processor. The input data is L1A and GEO data downloaded from the ocean color portal. However, the result processed by l2gen missed some data, which should related to the bowtie effect. I have tried to map it using reproject and mosai...

invalid south-west-north-east settings in V2021.2 ocssw
Hi, I updated my ocssw to V2021.2 recently in Ubuntu 20.04. I found the l2gen could not process the region of interest in MODIS Aqua imagery using south-west-north-east parameters. For example, the command such as l2gen ifile= A2020366063500.L1B_LAC geofile=A2020366063500.GEO ofile=A2020366063500_l2...
