Question: l2gen processing error - SDwritedata

Re: l2gen processing error - SDwritedata

The problem is that an HDF4 file can only store about 2G of data. With your requested products you can only output about 11000 lines before you exceed the HDF4 size limit. The input file has 17409 lines. I would suggest outputting netCDF files or using sline/eline to process half of the file in 2 ru...

Question: Python3 on Linux
Replies: 5

Re: Python3 on Linux

The problem is that you do not have a program called "python3"

Since you mentioned that you python is version 3 and not version 2.7, you need a link from python3 to python.
Assuming $HOME/bin is in your PATH, make a symbolic link

ln -s `which python` $HOME/bin/python3

Question: Parallel OCSSW l2gen code with OpenMP

Re: Parallel OCSSW l2gen code with OpenMP

OCSSW_MPI=1 is only used to enable a few of the libraries in ocssw/opt/src to be compiled with openmpi support. We have some radiative transfer code that uses MPI on a parallel processing computer we have. After the OCSSW_MPI environment variable is set to 1, make sure you rebuild ocssw/opt/src Ever...

Question: l2gen not using specific settings

Re: l2gen not using specific settings

The bug that you are seeing only happens when you use the north,south,east,west parameters. The bug was introduced between V2021.1 and V2021.2. It was fixed in T2021.11 and later If you do not want to install a newer version of the code you can - run lonlat2pixline to find the spix,epix,sline,eline ...

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.
