wrf output

Hello, I'd like to know if it is possible to use an environment variable to direct the output files from wrf.exe and if so, what the syntax would be in the namelist file. I'm thinking of something like the following: &time_control ... history_outname =...

Dear colleagues, (1). Please, how can I ensure that my simulation has a fine vertical resolution? (Vertical height above the ground). The e_vert? (2). How can I ensure that the values of snowfall and snow coverage are reset to 0 before each integration? (3). How do I exclude un-needed...

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...

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...

Hi all, I am running the WRF-Noah MP model in East Asia during 2021.6-2021.8 without any errors reported. However, I found some strange things in my wrf.output files: (1) Strange time dimension. Generally, my daily wrfout files have a dimension of 159*159*1 (My study area covers 159 grid...

Hi I want to remove some variables from my wrfout files but it is not removing any of the variables I put in the iofields_filename Here is my namelist.input and rsl.error file

Dear All I am trying to convert LCC projection to UTM projection using python. below is my code # Define the source (Lambert Conformal) and destination (UTM) projections lambert = pyproj.Proj(proj='lcc',lat_0 = 49.8, lon_0=6.0, lat_1=6.1, lat_2=12.2, a=6370000, b=6370000) utm =...

Can WRF-ARW perform a 3 day forecast based on historical data? I am trying to run wrf model beyond the given input days but it is getting stopped.

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...

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...

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...

Hi, Is it possible to specify the history_interval depending on the variable? I would like to have the output of the rainfall variables every 10 minutes but the output of the rest of the variables every hour. Thanks in advance !

Hi, all. question describe： I set the Mercator projection in the namelist.wps of WPS and set up 2 layers of nested areas. The latitude range of the first layer is -30~30, and the latitude range of the second layer is -20~20. In the output wrfoutput file, The lat range in the d01 result is...

Hi everyone, I encountered a problem that when I do a restart run wrf.exe recoeds output every time step regardless of the setting (recording outputs every an hour) in namelist.input file. How can I find a way to fix this problem?I was using WRF version 4.4. Thanks very much!

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...

Hello everyone, I'm new to WRF, Where can I find the fullform and definition of the all the variables in the "wrfout_d01_2022-10-31_01:00:00" file in the link below WRF_OUTPUT_FILES - Google Drive Thank you.

Dear community, I am using WRFv3.5.1 (for specific reasons). I'm trying to output terms like re_cloud and qc_diabatic, and for that I did some modifications to the Registry.EM_COMMON. After re-compiling, the variables are present in the wrfouts but however, the arrays only consist of zeros at...

Dear all, I manage to change the wrfinput file with a python script, I checked, and the variables I perturbed are different from the original wrfinput. Then I run the WRF Model with the perturbed input, but the output does not change. Better say, the resulting wrfout differs from the original...

Hi everyone, I am running the dust only simulatiion (chem_opt=401) with WRFV4.4. After the simulation completed, all the drydep_x variables in the output file are zeros. How can I fix this problem?Here is my namelist.input file. Thanks very much!

I noticed that wrf can produce a time series output at a certain location by presenting a 'tslist' file as shown in README.tslist. Is there any one have made it worked. In my experiments, I provided a file named 'tslist' in run directory, however, when the program is completed, I can not see...
