Description

From http://www2.mmm.ucar.edu/wrf/users/wrfda/index.html: "The WRFDA system is in the public domain and is freely available for community use. It is designed to be a flexible, state-of-the-art atmospheric data assimilation system that is portable and efficient on available parallel computing platforms. WRFDA is suitable for use in a broad range of applications, across scales ranging from kilometers for regional and mesoscale modeling to thousands of kilometers for global scale modeling. "

Running Program

Also refer to Running Jobs on the teaching cluster and to the documentation about our installation of WRF.

This module will load all other modules that it depends on.

After loading this module, the WRFDA executables (e.g. da_wrfvar.exe) will be available in your path.
