WRF Preprocessing System Version 3.6: Known Problems and Fixes

Running Program geogrid using MPI (posted 5/14/2012):

Problem: In v3.6, we introduced the ability in geogrid to write flags (global attributes) for any fields in the GEOGRID.TBL; however, geogrid was failing when run with multiple MPI tasks. The problem was that the calls to the WRF I/O API to write global attributes should only be made on the master task, rather than all tasks.

Solution: Download the fixed file, output_module.F, and place it in WPS/geogrid/src directory. Recompile.

plotgrids.ncl (posted 5/7/2014)

Problem: The 'plotgrids.ncl' file that comes with the WPSV3.6 tar file has a bug in it, causing it to produce a fatal error when it is run.

Solution: Inside the WPS/util/ directory, there is another file called 'plotgrids_new.ncl. This is the correct file to use.
