Testing— Background
Developers seeking to add code to WRF should consult the following documents:
Information for Code Contributors
Coding Standards and Testing Requirements.
These documents summarize the procedures and policies
regarding the contribution of code to the WRF system.
As described in Coding Standards and Testing Requirements,
the testing areas are: (a) software testing, (b) robustness testing,
and (c) reasonableness testing. Developers will perform the
software testing using the WRF software test suite.
Developers will perform the robustness testing
by running five cases for summer and five cases for winter.
Developers will perform the reasonabless testing by checking the output
from one of the summer cases and from one of the winter cases
with the comparison plots provided below, or by otherwise reviewing
the output of the simulation to make sure it is reasonable.
The materials for the software and case testing are provided
through this page.
WRF Software Testing
The WRF software test suite must be run on the code to be contributed. The materials and documents on them will be placed here.
Case Testing
Testing for both summer and winter cases is required. Files for running the cases are provided below.
Summer 2010 Cases
Listed below are the Metgrid output files for six test cases for summer 2010. The domain is over the US, with a grid size of 20 km covering 290x190 points. The namelist.input template has 40 eta levels. For the testing, developers should generate 24-hr forecasts for five of the initialization times.

* This case (2010061100) is also provided as a case to check if the result is reasonable. Plots for various fields from a reference simulation of this case are provided below for comparison purposes.
** To create your own plots to compare with the verification plots provided above, please use plot.ncl and make changes as necessary.
Winter 2012 Cases
Listed below are the Metgrid output files for six test cases for winter 2012. The domain is over the US, with a grid size of 20 km covering 290x190 points. The namelist.input template has 40 eta levels. For the testing, developers should generate 24-hr forecasts for five of the initialization times.

Updated Code
If you wish to use the code that is most up-to-date (prior to official release times), it can be found below. This will be updated each time new developments and/or changes are added. There are two tar files: one that is the full SVN code and the other is the SVN export code. Please keep in mind that this code has only undergone minimal testing.
