Activities for week of October 10, 2016
- Pull requests:
- From Jamie: instructions for hybrid were incorrect; ensemble perturbations should be in directory named "ep/" within working directory, not linked into the working directory
- Modified WRFDA regtest
- MAJOR BUG FIX: get_repo_revision returned wrong hash due to missing "chdir" into repository
- check for compatible netcdf/hdf5 builds on yellowstone
- Stop renaming da_wrfvar.exe to include compiler/parallelism in filename; this hasn't been necessary for a long time and is cumbersome
- Move addition of HDF5 library path to LD_LIBRARY_PATH inside the job script, so tests can easily be manually re-run
- From Jamie: Fix hybrid tests as above
- Add commit date to regression test online summary (not finished)
- Consolidate some RTTOV code and allow command line option to specify whether or not to compile with RTTOV
- WRFHELP emails

- Modified WRFDA regtest
- Allow command-line specification of a github fork to check out the code from
- Allow command-line specification of which tests to run, and only compile the necessary code
- WRFHELP emails
- Answered two questions from UMD user, one about VARBC, the other about satellite thinning
- User from University of Hawaii trying GPS_ZTD assimilation sent correction to help page (http://www2.mmm.ucar.edu/wrf/users/wrfda/OnlineTutorial/Help/littler.html#special); I verified the correction was correct and updated the page
