    Running MYNN on coarse and LES on fine grid - impossible or user error?

    Hello, I am running WRF to study downslope windstorms, and would like to use the MYNN (or other higher-level closure schemes) for the coarse grid (1 km or larger), as they've proved the best for this kind of application, and LES for a finer grid (say 100 m). However, when attempting to...

    BETR assignments by urban category (like AH, ALH, FRC_URB)

    I am a graduate student in Japan, sorry for my poor English. As the title suggests, I'd like to assign BETR by urban category. Although I have rewritten module_sf_urban.F and URBPARM_LCZ.TBL as in the attached file and run the calculation, only BETR is not loaded. I've already confirmed that...

    (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...
