There geolocation is not in the geophysical_data group. The lat/lon for each pixel is stored in the navigation_data group. Output from ncdump: group: navigation_data { variables: float longitude(number_of_lines, pixel_control_points) ; longitude:long_name = "Longitude" ; longitude:units = ...

Yes, looks like a shared lib problem. The demangled name is just "string.find()" _std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::find(char const*, unsigned long, unsigned long) const Could you try installing tag "T2023.9" I have fixed a few share...

with gcc11 you need some newer updates to the code. I have built opt/src and ocssw_src on ubuntu22.04 by installing tag T2023.5 install_ocssw -t T2023.5 --src cd $OCSSWROOT rm -rf build mkdir build cd build cmake .. make -j 20 install Your other option would be to install gcc-9, g++-9 and gfortran-9...

Thanks George, I'll look into it. I will also fix the benchmark scripts to deal with the new naming convention.

There was also a change made to process VIIRS J2 files properly:

- fixed tel_start_enc_nominal for VIIRS J2
- fixed missing sgli areosol default LUT

Every Level 2 NetCDF file has a set of flags in the variable l2_flags. Here is a dump of the definition: int l2_flags(number_of_lines, pixels_per_line) ; l2_flags:long_name = "Level-2 Processing Flags" ; l2_flags:valid_min = -2147483648 ; l2_flags:valid_max = 2147483647 ; l2_flags:flag_mas...

Our git repositories are not accessible to the public. You can use SeaDAS to install a released version of the source code. Use the SeaDAS GUI to install the OCSSW src. The code is also available on the web if you want to browse: https://oceancolor.gsfc.nasa.gov/docs/ocssw then click on: Files->web-...

Monthly data has the days averaged. If you want every day then grab the daily files.

You have found the MODIS Bowtie effect. Since the MODIS sensor has 10 detectors that take data on each scan, the position of the edge pixels at the beginning and end of the scan overlap the previous and next scan. Here is a web page describing this in more detail: https://oceancolor.gsfc.nasa.gov/do...
