Question: Update the ocssw processors failed

Update the ocssw processors failed

First, it is best to avoid installing the OCSSW processing system with "sudo".  Most users will want to install it in a normal user account without special permissions.  As previously discussed in these forums, Apple's python uses an obsolete ssl library.  You will need ...

Chl_a Averages

Depending on how you want to use the data, you may want to adjust the list of flags masked by l2bin or l2mapgen (or gpt Mosaic).   In principle, you can use l2bin with a whole month of level-2 files.  In practice that may hit resource limits.  Most use cases will have files binne...

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.

L2 chl Flags

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.

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 ...

Question: L2 Bin - processing ocean color data

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...
