wrf output

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...

I am using WRF 4.1.3 to run the model with WSM6 microphysic scheme (mp_physics = 6) and applying HAILCAST module in the inner domain. I'm obtaining results for WRF-HAILCAST MAX Hail Diameter, however I can not take any hail (HAILNC). I obtain zero for all domains. I tried to turn on hail_opt...

Hi everyone, I need help with changing the axis of my plots from the domains to the variable unit. For example from bottom_top to meters or kilometers and from west-east to like temp in Kelvin. Attached is a copy of what i have now

Hi, I am new to WRF, I have some questions about how to add advection and tendency variables to wrfout file. I found these variables in Registry.EM_COMMON, and I have read the "How to Use the WRF Registry". I notice that the I/O of these variables is "h", but there is no these variables in my...

Recently I am running WRF simulation, the simulation time is relatively long, the met_em* file as input data is one per hour, and a lot of CPU is used at the same time... This resulted in a lot of links to met_em.d01* files in the folder where I ran WRF, and a lot of rsl.out.xxxx and...

Hello, I want to use &AFWA to calculate the visibility. In the model output file, the values of the AFWA_VIS was 10 times approximately as large as the GFS 0.25° dataset and observation data in my study area, especially on land. I used different combinations of physical schemes, however the...

hello! I'm attempting to use &diags output the wind, temperature, dew point temperature at 50m,100m and 110m, but in the output filed the TD_ZL, T_ZL, U_ZL, V_ZL were -999 on land, the variation trend of the values were normal on the sea. I'm not quite sure now how to go about fixing the...
