    Possible namelist error? WRF stops in middle of run

    Using WRF-CHEM v4.4.2 and sometimes the 120 hour run works without a problem. Other times it stops mid run. I have attached the rsl files and namelist.input.

    Is there a way to append file type to wrfout files?

    Good afternoon, I was wondering if there is a way to append the file type (ie .nc .grib) to the wrf output files as part of the nameslist? This would make it easier to do data analysis.

    Underestimated CLDFRA in 4.4.1 compared to 4.3.1

    Hi All, Significant differences were found in the SWDOWN calculation between WRF-4.3.1 and WRF-4.4.1. Compared with measured radiation data, WRF-4.4.1 shows much worse scores. Similar differences are in CLDFRA: compared to satellite observation WRF-4.4.1 underestimates the values of the...

    How to calculate dbz using WRF? Namelist issue

    Good morning, Trying to calculate radar dbz returns over domain 2. I have attached the namelist file for reference. It seems like even though I am using a compatible mp_physics the do_radar_ref doesn't want to work. I have attached my namelist and rsl.error reports in a zip file.

    The problem of the auxiliary pressure level output in WRFPLUS

    Hello. When I was using the auxiliary pressure level output in WRF, for example, I just add &diags p_lev_diags = 1 num_press_levels = 1, press_levels = 50000, in the namelist.input and auxhist23_interval = 360, frames_per_auxhist23 = 1, io_form_auxhist23 = 2, in the &time_control part, if I run...

    Units of west_east and south_north coordinates?

    Hi all, I'm a new WRF user and want to know the values in km of the gridpoints in some WRF output I am working with. I noticed that much of the output data is in coordinates of 'west_east' and 'south_north'. However, I have been unable to figure out whether these coordinates simply indicate the...

    Idealized test cases output as RotatedLatLon projection, why?

    Hello! I've successfully set up WRF and have also run a couple of the test cases included in WRF4.4.1 (em_fire, em_quarter_ss). These runs are successful as well and output the standard `wrfout_d01_0001-01-01_00:00:00` type files. I then attempt to visualize these files (example, SLP) using...

    WRF model runtime issue: Only able to run 9 days out of 152 due to HPC time limit

    Hi everyone, I am having an issue with running my WRF model on two clusters with 35 nodes each. I set the maximum time limit to 24 hours, but my model runtime is 152 days, or about 3 months long. As a result, I've only been able to run and output about 9 days out of the 152 days. I had to...

    5 layer thermal diffusion scheme vs. NOAH LSM, temperature results

    I am evaluating the results between different Land Surface Models used in WRF. When using the NOAH LSM, I get more accurate 2 meter temperature results compared to the 5 layer thermal diffusion scheme. The 5 layer thermal diffusion scheme yields less accurate and LOWER temperatures. What about...
