These are the steps to follow to install new WRF versions on NCI machine. Only for admins within the wrf group at NCI. If starting from scratch:

  1. Under your own project, clone the WRF github repo: https://github.com/coecms/WRF and create a new branch for the new version (named Vx.x.x), starting from the most recent HEAD (not master)
  2. Add https://github.com/wrf-model/WPS.git and https://github.com/wrf-model/WRF.git as remotes (named NCAR_WPS and NCAS_WRF if you want to copy-paste the commands) and fetch
  3. In the new branch, run the command:
git merge -s recursive -Xsubtree=WRFV3 --allow-unrelated-histories NCAR_WRF/master

You may need another branch than master to pick up a specific release.

  1. You may need to update the crtm coeffs. You'll probably get a conflict on the file WRFV3/var/run/crtm_coeffs. This is a link to /projects/WRF/data/WRFDA_files/crtm_coeff_X. Check the version the remote points to. If different from local, download the updates from: http://www2.mmm.ucar.edu/wrf/users/wrfda/download/crtm_coeffs.html
  2. After resolving conflicts, run WRFV3/configure. See what options are correct for the machine architecture. Update WRFV3/run_compile appropriately.
  3. Clone into /projects/WRF with wrf group ownership. Make sure the master branch there points to the new version branch.

Follow same steps for WPS, but remote is called NCAR_WPS and -Xsubtree=WPS

Jenkins setup

  1. Add a new parameter for the version. Just the numbers, no "V".
  2. Create a branch for that version in wrf-testing repo. Exact same name as the previous step parameter.
