The CLIMAF installation is a special case, because we may want to use it with the Python installed for CDAT, but it is not installed using conda and should theoretically work with any available Python, as long as the directory where it is installed is correctly defined in the PYTHONPATH variable

We follow the steps for the installation of a non-standard server

• Go to the appropriate installation directory (we choose the directory where we have also installed miniconda3):
  • LSCE: cd /home/share/unix_files/cdat
  • ciclad: /data/jypmce/cdat/
• git clone https://github.com/senesis/climaf climaf
• Add CLIMAF to the PYTHONPATH environment variable
  • LSCE & tcsh: setenv PYTHONPATH ${PYTHONPATH}:/home/share/unix_files/cdat/climaf
  • LSCE & bash: export PYTHONPATH=${PYTHONPATH}:/home/share/unix_files/cdat/climaf
  • ciclad: same as above, using /data/jypmce/cdat/climaf
• Test the installation
  • make sure the Requirements are available:
    • LSCE: module load netcdf/4 nco cdo ncl ncview
    • ciclad: module load netcdf4 nco cdo ncl/6.3.0
    • optional: start an X server

    • cd climaf/testing
      ./test_install.sh

• Once the tests are OK, add the required module load and environment variables definitions to the .basrc and .cshrc files
  • Maybe these lines should go to the .profile and .login files…(check Bash Startup Files)
  • Loading some modules may have some side-effects on CDAT. If that's the case, use module purge before initializing CDAT
  • LSCE: add to your ~/.cshrc file (check ciclad below if you are a bash user)

    • # Prerequisites for using CLIMAF
      module load netcdf/4 nco cdo ncl ncview
      
      # CLIMAF environment variables
      setenv CLIMAF /home/share/unix_files/cdat/climaf
      setenv PYTHONPATH "${PYTHONPATH}:${CLIMAF}"
      #setenv PYTHONPATH $CLIMAF
      setenv PATH "${PATH}:${CLIMAF}/bin"
      setenv CLIMAF_CACHE "/home/scratch01/${USER}/climaf_cache"
      setenv TMPDIR $CLIMAF_CACHE
      setenv CLIMAF_LOG_DIR $CLIMAF_CACHE
      
      #conda activate cdatm_py2

  • ciclad: add to your ~/.bashrc file

    • # Prerequisites for using CLIMAF when not using the 
      # default 'module load climaf'
      module load netcdf4 nco cdo ncl/6.3.0
      
      # CLIMAF environment variables
      export CLIMAF=/data/jypmce/cdat/climaf
      #export PYTHONPATH=$PYTHONPATH:$CLIMAF
      export PYTHONPATH=$CLIMAF
      export PATH=$PATH:$CLIMAF/bin
      export CLIMAF_CACHE=/data/jypmce/climaf_cache
      export TMPDIR=$CLIMAF_CACHE
      export CLIMAF_LOG_DIR=$CLIMAF_CACHE
      
      #conda activate cdatm_py2

• Open a new shell and run the tests again. If there is an error that was not there, check what you have added to the shell init files

We are now ready to start using CLIMAF on ciclad!
