Question: SeaDAS, LUTs
Replies: 6

Re: SeaDAS, LUTs

If you have installed a sensor using the SeaDAS GUI or install_ocssw, the aerosol LUTs will be in:

$OCSSWROOT/share/<sensor>/aerosol/*

Hope that helps.

Question: L2gen fail with exit code 1

Re: L2gen fail with exit code 1

Thanks George,

I get the same core dump when producing sst_tripple on a MODIS file. We will enter a bug report. L2gen should catch products that can not be produced and print out a reasonable error.

Question: Errors in building ocssw processing executables

Re: Errors in building ocssw processing executables

Actually I had to fix a few things in the CMakeLists.txt file. You will need to use "--tag T2021.23". You will not be able to build the VIIRS code so do not turn on the BUILD_ALL or BUILD_VIIRS_L1 flag for cmake. The process becomes: export OCSSWROOT=/home/colapao/seadas-7.5.3/ocssw instal...

Re: Errors in building ocssw processing executables

I would suggest not building the VIIRS part for now. I have to make a few sets of libraries to export for that to work. Try this:

Code: Select all

cd /home/colapao/seadas-7.5.3/ocssw/ocssw_src/
rm -rf build
mkdir build
cd build
cmake .. -DBUILD_VIIRS_L1=OFF
make -j 20 install
Let me know how that works.

Question: l2gen segmentation fault

Re: l2gen segmentation fault

Yes, the n,s,e,w params for l2gen are more convenient than grabbing the output of lonlat2pixline. I am almost done fixing the bug. Expect the fix in the next release.

Thanks again for finding this.

Re: l2gen segmentation fault

OK, looks like the n,s,e,w params for l2gen processing VIIRS has a nasty bug in it. Here is what I suggest for your processing stream. - run lonlat2pixline with the GEO file and n,s,e,w to get start/end, line/pixel for region of interest - run l2gen with L1A and GEO file and start/end, line/pixel pa...

Re: l2gen segmentation fault

I can reproduce the seg fault on my Linux machine. Seems to work fine on my mac, but that is how these memory issues usually behave. There is an easy work around that you can put into your processing stream. l2gen works fine if you use an L1B file as the ifile instead of an L1A. Using the example fi...

Question: how to use IOP models with GOCI-II

Re: how to use IOP models with GOCI-II

The best way to solve this is to write a GOCI-II reader for l2gen. Currently, we do not have plans to write one. We do supply the source code, so others can contribute. Here is what I see as the major issues for you: - l2gen is written in C/C++, so it is easiest to write the reader in C++. - l2gen d...

Re: l2gen segmentation fault

Can you give me the exact command lines you are using to go from V2016258230600.L1A_SNPP.nc to the subsetted files that makes l2gen crash? I will try to reproduce the crash here.
