running wrf-chem

  1. J

    wrf-chem tutorial exercise 1:after running real.exe,when l used nvciew viewing wrfinput_d01,the value of dust_1 is all 0.

    i wonder why this happens ?how can i solve this problems? namelist.input is below. thank you very much!

    Are the SW Accumulated and Instantaneous Fluxes variables not printed in the WRF-Chem output file while considering Goddard SW Radiation Scheme?

    Dear all, I used the Goddard scheme for SW Radiation and the RRTMG scheme for LW Radiation while running WRF-Chem using RADM2-MADE/SORGAM chemistry options. I want to calculate the net SW radiative flux in the atmosphere using this formula:ΔFatm = ΔFTOA - ΔFsurf However, I noticed that only the...

    Query on the unit conversion formula of the aerosol species output of WRF-Chem simulation

    Dear everyone, I have some doubts about the unit conversion of aerosol species. I ran WRF-Chem using the RADM2-MADE/SORGAM chemical mechanism. I viewed the output using the MATLAB command ncdisp. Some portions of the displayed lines are as follows: eci Size: 405x415x34x217...

    absence of initial variable conditions in the wrfbdy_d0* file

    Dear all, I add many variables in the Registry(about 1661 variales). And when I add the initial and boundary conditions(./mozbc) to generate the wrfbdy file, the some of the initial values of the variables (after about 386th variable) do not appear in wrfbdy file and thus when I run...

    Segmentation fault with MOZCART and Finn

    Hello all, I am using FINNv2.5 for a biomass burning simulation with WRF-Chem v 4.4.1 using MOZCART. I have attached my namelist and rsl file. However, I am running into a segmentation fault that I do not understand how to fix. Any help would be greatly appreciated. Below is part of the error...

    Which way is the more computationally efficient for running wf.exe with one way nesting: (a) by setting feedback to '0' or (b) using ndown.exe?

    Hello everyone, I want to run wrf.exe (WRF-Chem) with one-way nesting because of the limitations of my system (a linux server with 378 GB of RAM and 32 processors). I have gone through the WRF user guide, which explained how to do one-way nesting using 'ndown.exe'. Also, I found the following...

    Error in running WRF-Chem (for version 3.9.1.) while using chem_opt=202 though WRF-Chem is running successfully for chem_opt=112 and 201

    Hello everyone , I am giving a test run with two domains (d01:20 km and d02:4 km) with one-way nesting by setting 'feedback' option to '0' for just 2 days. The WRF-Chem ran successfully when I used the MOZCART option (chem_opt=112) and MOSART-MOSAIC (chem_opt=201). But, some specific errors only...

    WRF-Chem simulation stopped without showing any error in the rsl.error* file

    Hello everyone, I was able to run real.exe successfully, and then I was also able to make the chemistry input files that are needed to run wrf.exe. Then I gave the following command: mpirun -np 28 ./wrf.exe >& wrfrun.log &. At first, the simulation went on for some time, but then it stopped...

    WRF-Chem-4.2. Run with Chem_opt=198 (SAPRC99/MOSAIC)

    Dear community, I am trying to run WRF-Chem with the SAPRC99/MOSAIC mechanism, adding anthropogenic emissions from a local emission inventory. However, after searching in the WRF-Chem user guide, I could not find a suitable emiss_inpt_opt for this mechanism. Does anyone know what...

    WRF-Chem stops after exactly 1 day - Why?

    Dear WRF-Chem users, I am currently facing an issue where I try to run 7 consecutive days of WRF-Chem simulation. The run is able to finish day 1, but stops at the beginning of day 2. This was reproducible. I have attached the namelist.input file and rsl.out.0000 with a debug level of 50...

    WRFchem stops after "aerosols_driver calling sorgam_driver"

    Dear All, I am running wrf/chem v3.9.1. The running got stuck after "aerosols_driver calling sorgam_driver." It didn't crash but not writing output anymore. I used "chem_opt=2," and I think that's the problem cause it went through after changing to "chem_opt=1". So I guess that the problem lies...
