    Accumulated precipitation in WRF

    Hi, I am new to the WRF model and am using someone else's data (so I don't have access to the namelist file etc.). I am wanting to examine how the accumulated precipitation varies during the simulation. I saw on some other posts that the variables to use for this are RAINC and RAINNC. However...

    Generating (and perhaps extracting) global meteorological data from WRF - with compensation and/or co-authorship

    Hi all, I am not an atmospheric chemist, but I am an environmental modeler and wear multiple hats, including as a consultant. We have a project using a VOC/Ozone model around the globe, and so we are looking for global weather data. It appears WRF would be suitable, except for its learning...

    WARNING: No channel points found for CHRTOUT

    Hi everyone, I was confused about the warning messages for a long time. I really appreciate it if anyone can provide some suggestions on fix it. I used wrf_hydro_arcgis processing tools to generate routing files. During the process, I added a cvs file that lists the location of each forecasting...

    Not really sure how to use e_vert and stretching

    Good morning, Could someone please explain how to use e_Vert and the stretching variables? Like I have read the tutorials and I am still not sure how to use it properly. I have attached my namelist.input for someone to help me.

    Reoccurring trend in WRF results (solved)

    Hi all, I'm not sure how to clearly describe my problem, but I have tried to take the mean value of my area and plot this over all the days I modelled to get a view of the season bond variations. However, as shown in the figure below, the same trend occurs 3 times in my output, which is...

    input data for WRF-Hydro

    I am a beginner to the WRF-Hydro model. I would like to simulate groundwater for an Indian region. WRF-Hydro is providing the groundwater bucket parameter and in India in-situ groundwater level is available. My questions are: 1. How can I compare the WRF-hydro output (groundwater bucket...

    timezone in WRF

    Hello. I'm beginner to the WRF model. I was wondering about the default timezone in WRF. If I use a UTC-based input, the output will be in UTC, no matter where the domain is located, right? So if the model start time is 00:00 UTC on 1 October 2021, will the solar insolation or altitude in the...

    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.

    Use of Environment Variables to Direct History Output Files

    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 =...

    Fine vertical resolution, excluding unneeded WRF-output files, resetting snowfall and snow coverage to 0 before each integration

    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...

    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...

    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...

    Strange time dimensions and values of wrf_out files

    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...

    3-day ahead weather forecast using WRF-ARW based on historical data.

    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.

    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...
