Chl_a Averages

It sounds like you may be planning to average the daily mapped files to get 8-day and monthly mapped files.   You can streamline things a bit by using l3bin to combine daily binned files into 8-day binned files, and then combining three 8-day files with a few daily files to get monthly bin...

L2 chl Flags

Sounds like you need to adjust the values in $OCSSWROOT/ocssw/data/common/product.xml.  Since that file is managed by git, will want to create your own local branch.  Sean recently posted an example of this for a customized script, but the same principle should apply for product.xml.

Which files are you using?   Are you using the OCSSW Processing System? Level-2 NetCDF files from l2gen have:chlor_a:valid_min = 0.001f ; chlor_a:valid_max = 100.f ;  These are set in the product.xml file and also appear in level-3 mapped files (either carried through or set from the ...

building SeaDAS 7.3.2 on CentOS 7.3

I was able to build the OCCSSW Processing System on CentoOS 7.3 (using a very old, slow, unloved and unwanted PC for testing).    I think you are missing some static libraries.  I have: sudo yum install glibc-static libgfortran-static zlib-static gmp-static libjpeg-turbo-static libstd...

Installing OCSSW processors

Try a lowercase "V" in the git-branch, as in: "--git-branch=v7.3 ".   If you have problems with python scripts and https URL's, see New thread on manual update of OCSSW processors.

Have you tried adding the pixel size variables, e.g., from gpt.command Mosaic -h   -PpixelSizeX=<double>            Size of a pixel in X-direction in map units.                              ...

disabling utcpole.dat/leapsec.dat update

It is much safer to run install_ocssw.py as a normal user, e.g., without using sudo.  Some linux distros will prevent regular users from completely filling the disk, so when you run out of space you could see a useful error message instead of a crash.   The simplest way to recover is ...

L2 Bin - processing ocean color data

The real documentation is the source code.  In $OCSSWROOT/run/build/src/l2bin/l2bin.c, search for 110 and you will see that when no bins are filled, the output file is removed and ret_status set to 110: printf("total_filled_bins: %d\n", total_filled_bins);    if (total_fille...

Update the ocssw processors failed

I have MacOS El Capitan v 10.11.6 (with the supplemental security update), but your version should work once you have newer openssl support in some python-2.7.   The Apple version pf python-2.7 uses a very old openssl library that does not work with the NASA servers.   Macports o...

Update the ocssw processors failed

Running ./install_ocssw.py --install-dir=$HOME/ocssw --direct-broadcast without the --git-branch=v7.3 resets the branch to "master".    When things aren't working smoothly it is a good idea to add the -v flag for verbose output.  You would have seen messages like "S...
