    WRF Solar Roof Effiency

    I wonder what is the conversion efficiency of the solar photovoltaic panel in WRF-BEP&BEM? Is it possible to get data on energy savings from photovoltaic panels? @Andrea Zonato @Wei Chen

    ./wrf.exe Status = -4 ---- ERROR: Could not find matching time in input file

    Dear friends, I missed an error when I run the ./wrf.exe in WRF-noahmp. here touched my namelist.input and some input data. when I change the time_step from 180 to 120 to 90, it always said the same error in the different time, such as 2020-07-03, 2020-07-14, 2020-09-18. **WARNING** Time in...

    How to perform a long-time WRF simulation effectively?

    Hi all, I'm planning a long-term WRF simulation (about 20 years, 2000-2020) using six-hourly input data from ERA5. I am considering two options: Running annually with restart files. Running each year in parallel with additional spin-up time (e.g., 2 weeks). Given that my input data remains...

    Problems with tc.exe at southern hemisphere

    Could anyone help me? I'm trying to run tc.exe for a southern hemisphere case, but although it generates a auxinput1* file, and the real.exe does not signal any problem, the wrf.exe fails. Using the wrf_metgrid2.ncl, I've plotted the original met_em_* and the auxinput1* files, and I attached...

    How to Determine the Building Floor Heights in WRF-BEM Simulation:

    Hello! As a newcomer to WRF-BEM, I understand that the parameter `num_urban_nz` is defined as 18, which divides the building into 18 vertical layers. Does this 18-layer division correspond to the number of floors in real-life buildings? In URBPARM, it mentions air conditioning settings—are these...

    How to Determine the Building Floor Heights in WRF-BEM Simulation:

    你好!作为WRF-BEM的新手,我知道参数“num_urban_nz”被定义为18,它将建筑物分为18个垂直层。这种 18 层的划分是否与现实生活中建筑物中的层数相对应?在URBPARM中,它提到了空调设置——这些设置是否分布在建筑物的每一层?模型中是否有设置每个建筑物楼层高度的选项? 我希望收到您的回复,谢谢。

    Problem while running WRF-Chem V4.5 with chem_opt=301

    The program got stuck without any error message. No output or log entry appears even after 20 hr. I had to kill the program forcibly.

    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...
