    metgrid.exe crashed when using different src data

    Hello, I would like to running a wrf based on a combined field which consists of ERA5 field and the GFS RH field. In order to achieve this, I had editted the Vtable file and ungribed them seperately. 1) For ERA5 dataset: edited the Vtable file, remove the RH field of record, reivsed the...

    I created new met_em files while wrf.exe was running. Is it a problem?

    Hi I was running a simulation and I forgot to check if WRF was finished before creating new met_em files for use with Thomson aerosol-aware (mp_scheme = 28). When it came to my mind, I checked rsl.error.0000 and wrf.exe was still running, it was coming close to the end of the simulation. I...

    Is it recommended to use the same spatial resolution for all surface parameters?

    Dear users, The WRF model has 30 arc-seconds (~900 meters) as the higher spatial resolution by default. I read many papers where authors changed the topography (HGT) to a higher resolution (e.g. 90 meters). I also managed to change it. But now I have a question. The another surface parameters...

    (Resolved) Why real.exe doesn't use all met.em.d0* files?

    Hi there! I got a question when executing real.exe. I used three levels of nesting. Each nested area has 8 met.em files with a time resolution of 3h. I found that after deleting some of the met.em files in d02 and d03, the real.exe program can still run normally, and eventually SUCCESS...

    Using the ERA5 land/sea mask data in WRF

    I have noticed that there is an issue with the land sea mask that you get from ECMWF is not binary. This is also noted on ECMWF webpage: Land-sea mask in ERA5 and ERA-Interim - Copernicus User Support Forum - ECMWF Confluence Wiki Because the mask is not binary I believe it creates an issue...
