wrf2gem

My WRF to GEMPAK conversion code is contained in the following archive:
Version 1.3.1 - wrf2gem.tar.gz (36 K)

To compile the code, I have included a Makefile that you'll probably have to modify. Enjoy!

What's New

• Fixes geopotential height for WRF version 2.2 (but breaks it for older WRF output)
• Modified Makefile for GEMPAK 5.9.4

Common Problems

• Your compiler may complain about not finding netcdf.mod. There are a number of ways to fix this:
  • Add the flag -module /dir/to/netcdfmodfile to the compiler options. (A different flag may be required if you are not using pgf90.) This allows your compiler to find netcdf.mod.
  • Create a symbolic link to netcdf.mod in your source directory.
  • (Most general fix) Create a symbolic link to netcdf.mod in /usr/local/include.

Older Versions

• Version 1.3 9 January 2006
  • Can now handle x-hr precipitation accumulations (diagnostics 104—7) when each history file contains one output time, thanks to Kate LaCasse
  • More new variables and diagnostics (Kate LaCasse)
  • Initial date and time of the model run is now always automatically detected, so there's no need to define this in the namelist
  • Minor bug fixes
• Version 1.2 13 June 2005
  • Added new category of diagnostics that are output on isobaric levels
  • Fixed bug in netCDF interface

  • Some efficiency improvements
• Version 1.1 23 March 2005
  • Increased flexibility of program through additional options in convert.nl, thanks to Kate LaCasse
  • Fixed bug that prevented program from working when there was only one output time
