Re: Multilevel_processor issues

Can you show me the image of the 4 L2 files you created through the modis_GEO -> modis_L1B -> l2gen step by step process instead of through multilevel_processor?

Re: Multilevel_processor issues

I tried multilevel_processor GUI with your setting, with the content of _inputFiles.lst as following -- corresponding to the files 119, 120, 121 and 122 on your attached image: /Users/***/Scenes/MODIS_AQUA/forum/A2004291221000.L1A_LAC /Users/***/Scenes/MODIS_AQUA/forum/A2004292211500.L1A_LAC /Users/...

Re: VIIRS l2gen error in initialization

You can try to extract the L1A file to your region of interest, generate a geolocation file for the extracted L1A file, and then process the extracted L1A/GEO data with l2gen using the same par file content except the north/south/east/west options

Re: import modules.ProcUtils as ProcUtils

In SeaDAS 7, modis_GEO.py and getanc.py are in $OCSSWROOT/scripts, and anc_utils.py is in $OCSSWROOT/scripts/modules. In SeaDAS 8, modis_GEO and getanc are in $OCSSWROOT/bin, anc_utils.py is in $OCSSWROOT/bin/seadasutils. You need to call $OCSSWROOT/bin/modis_GEO rather than modis_GEO.py What was th...

Re: Multilevel_processor issues

I did modis_GEO, modis_L1B and l2gen step by step on A2004006210000.L1A_LAC and created A2004006210000step.L2_LAC_OC And I tried multilevel_processor GUI with your setting(with A2004006210000.L1A_LAC being the context of _inputFiles.lst), and created A2004006210000mlp.L2_LAC_OC. This is Rrs_469 in A...

Re: Multilevel_processor issues

Please let us know a few things so we can replicate the error:

1. what version of SeaDAS and what tag of OCSSW you are using.
2. the name of an L1A file you processed
3. the input settings for the processors if not default
4. command line or GUI

Re: Error: band does not contain integer pixels

Thanks for reporting the bug.

The new version of the NSIDC sea ice file has 3D arrays, but one dimension is unity. It seems that we need a new reader for it.

We'll work on it.

Re: Extracting spectral data from L1B netCDF4 files

For your first question, there is a bug in SeaDAS 8.1 that it does not show Lt band in HICO L1B files. It's fixed, and the fix will be in the next release 8.2.
