    WRF-Chem Simulation Freezes with UCM Enabled at Emission Calculation Step

    Dear WRF-Chem Community, I am encountering an issue with my WRF-Chem simulation when the Single-Layer Urban Canopy Model (SLUCM) is enabled. I have successfully incorporated Urban Canopy Parameters (UCPs) for 60 cities in China into the GEOGRID, and I have verified that the WRF input files are...

    e_ch4 emission input is not being read when included in the MOZMEM chemical mechanism using emiss_opt = 10

    Hi, I am working with WRF-Chem v4.6.1 using the MOZMEM chemical mechanism and have set emiss_opt ==10 to read point source emissions. I have a point source emission inventory that includes both CH4 (methane) and benzene. The model correctly reads e_benzene emission and generate benzene output...

    Real.exe is successfully running with wrf_chem_input but producing a wrfinput without values for the chemical species.

    I am a relatively new user of WRF-Chem. I am using the version 3.9.1.1. When running real.exe with wrf_chem_input for a day the program runs, but the wrfinput file produced have zero values for the chemical species. The wrf_chem_input file I am using is actually the last wrfout from the previous...

    Issue with PM2.5 and other pollutants output in WRF-Chem

    I have successfully ran wrf-chem using below namelist file. I got wrfout file for time period which i took. But while potting I am unable to see variables like PM2.5, PM10, SOx, NOx, NMVOC, NH3, CO. For my study I want to show a comarison between wrf output and observed value for these...

    Compiling WRF Chem with KPP

    I'm only interested in getting the KPP files to compile for a specific WRF mechanism. I don't have a preference for the version of WRF, but I'm using 4.5. I'm compiling on Derecho, but ultimately, I want to set up a Dockerfile to compile the KPP files for different mechanisms since that's all I...

    WRF-Chem (GHG) can't find VPRM TABLE

    When I run wrf.exe it says NO PARAMETER TABLE IS INCLUDED FOR THIS VPRM TABLE OPTION! Here is my error.log and namelist.input. I didn't find the VPRM TABLE in chemics_init.F either. If anyone can respond, I can't thank you enough.

    disable chem impacts on met

    Hello, I understand how to run WRF-Chem with/without aerosol direct&indirect effects. But to run the model without the chemistry impacts on the meteorology, do I only need to turn off aer_ra_feedback in &chem? Is there any other settings needed to be changed? Thanks, Suqian

    sea salt simulation

    Hi, I've been trying to figure out how to make some sea salt simulations over the colombian caribbean, but I have came across so many problems with the namelist.input. I have not been able to find a clear documentation about the chemistry module of WRF and even less about sea salt modelling with...

    Differences between compile and compile_new with WRF v4.6?

    Hello all, I'm trying to compile WRF v4.6.1. I noticed that for version 4.6 and 4.6.1 there are configure_new and compile_new along with configure and compile. While for older versions, they only have configure and compile. I'm wondering what are the differences between configure and...
