    Metgrid run with dmpar (parallel run)

    I am running WRF using WPS 4.4 version and would like to run metgrid using dmpar. As a result of searching through previous posts, I saw many people recommending serial because its performance is not bad. However, since we are trying to reduce the WRF execution time as much as possible, we are...

    Overlapping domains

    I am currently designing an OSSE using a single domain convection-allowing nature run and single domain control runs at the same resolution. The only difference is in the location and size of the domains - the nature domain occupies a much larger area. For ease of verification, I'd like to...

    Feature Request: Example namelists for all 4 different projections

    I have noticed in the WPS folder of WRF that the namelist.wps examples are typically using Lambert projections. But based on the user's guide section on namelist.wps ( The WRF Preprocessing System (WPS) — WRF Users Guide documentation ) some of these variables change and/or not needed when...
