wrf output

Dear, I have a tough problem about wrf-chem. The error is below: newnucbb mins 2.33E+02 5.00E-02 1.07E-13 7.11E-17 4.58E-22 0.00E+00 newnucbb maxs 2.83E+02 9.75E-01 1.29E-09 8.87E-13 1.32E-10 9.30E+05 newnucbb avgs 2.52E+02 5.64E-01 2.47E-10 2.49E-13 4.69E-12 1.25E+04...

In WRF, it is possible to output RMOL=1/L (where L is the Monin-Obukhov length). What formula is used to calculate this L

Hi everyone, After working a lot with the real WRF configurations, I am now in the process of setting up idealized WRF simulations. I am using WRF v4.6.1 and compiled for the em_les case. When running the simulation with two nested domains, I observe strong streaks in many of the 4D-output...

My Python code works correctly for everything else, but I encountered this problem on the last run. What could be the reason?

Hello WRF forum, I am attempting to run WRF Real past spin up time, and then perturb the temperature and pressure fields in a restart file. However I seem to be missing something, because when I restart WRF the edited and perturbed WRF variables disappear. They seem "not to stick." See this...

Hi, I am experiencing a persistent WRF crash at a specific simulation time. WRF 4.7.1 consistently crashes at 2019-06-19 05:19:32 UTC across multiple attempts with different configurations. The previous day (June 18) completes successfully with identical domain and physics settings, but June...

I am trying to simulate WRF and getting a step-kind of transition near the coastlines of India (ECMWF seasonal simulation data as initial and boundary conditions). Attaching namelist.wps, namelist.input, and some screenshots of output variables (surface and pressure level variables). Please help...

Hi, I'm adding microphysics source/sink terms to WRF output by modifying: Registry/Registry.EM_COMMON - Added variables (EPRDO, EPRDGO, etc.) phys/module_mp_morr_two_moment.F - Calculated variables in microphysics scheme phys/module_microphysics_driver.F - Passed variables through driver...

Hi, I'm using ERA5 pressure-level and surface data as forcing for a WRF simulation over Chicago. Initially, I used the recently published era5_to_int.py tool to convert ERA5 netCDF files to intermediate and then metgrid files, following the workflow described here...

Hi everyone, I’m working with WRF v4.6.0 + WPS 4.6 and running simulations with SLUCM / BEP over a metropolitan area. I have high-resolution urban morphology data (building height, plan area fraction, street width) derived from GIS sources. My main confusion is about the correct workflow to...

I’m running a WRF simulation and would like to output radiation flux across all vertical levels in the model. However, I haven’t been able to find any 3D radiation flux variables in the wrfout files or in the Registry. Has anyone done this before, or can point me to the correct fields or...

Hi, I'm using run_wrf.pbs to run a WRF simulation. Originally, I use this parameter set in the .pbs file: #PBS -l select=8:ncpus=30:mpiprocs=30:mem=64GB But it was running slow, so when I restart this job I changed the parameters to increase node number: #PBS -l...

Using the ECMWF Climate Data Store (CDS) to Download ERA5 Data in a Conda Environment This guide shows you how to: Create a Conda environment called CDS with pip and cdsapi Activate the environment Set up your CDS API token (.cdsapirc) Use the Python script Download_CDS_ERA5_Data_Hourly.py to...

Hello, I would like to ask about about wrf. More speciafically, the variable 'WD10' represents the wind direction. I would like to confirm that the directions of the output is 0 : North, 90: East, 180: South, 270: West, where I am referring to the origin of the wind ( 0 degrees, the wind comes...

Size of wrfout file decrease from 379M to 79M using WRFV4.6.1 as show in the figure blow. Moreover, model was't interrupted. It is so confused. if you have some ideals about that, looking forward to your reply! Thanks a lot!

Hi all, I ran a simulation with opt_run = 5 and obtained negative values for water table depth (ZWT), see Fig below(first output, simulation starts at 2013-01-01_00:00:00). ZWT in wrfinput is zero. As I understand it, ZWT is defined as positive downward. When using opt_run = 1, ZWT remains...

I am attempting to run WRF with a perturbed wrfinput file that was generated by da_wrfvar in the WRFDA suite. Both WRF and WRFDA are version 4.6.1, downloaded and compiled from the GitHub repository, but I receive the following error when running wrf.exe: DYNAMICS OPTION: Eulerian Mass...

Hi all, I'm encountering a strange issue with auxiliary history output (auxhist7) during a long-term WRF simulation from 2013 to 2022. My Configuration: Regular output: Daily files auxhist7: Hourly output (for specific variables) auxhist7 settings: iofields_filename = "my-file_d01.txt"...

I am new to WRF (so bear with my question) and I am running two different WRF simulation, to down scale GFS data with 3 nested domains. The two simulations have same settings but they differ in the time control both for wps and wrf. One is ran for 10 days: start_date = '2024-11-01_00:00:00'...

Hi, I successfully ran WRF-Solar v4.5, and the rsl files also show that the external input AOD files were read, but the output results show almost no difference. I’d like to know why this happens. I noticed that although it shows the data being read, the data is not actually being used in the...
