    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...

    Using MOSAIC with Dust Emissions

    Hello, Is there a way to use MOSAIC with dust emissions in the WRF-Chem model? MOSAIC has 4 dust bins, while dust_opt uses 5 bins. I saw this post from a few years ago Problem running CBMZ-MOSAIC (4 bins) with AFWA dust scheme and was wondering if a solution was found. Thanks, Alexander

    any other process change chem array outside chem?

    Hello, I am wondering if there are any processes would change chem array (e.g. gas) outside of chem (chem_driver)? I have checked the dyn_em and PBL, shallow cumulus won`t change chem in my case. But i am not very familiar with the other processes beyond chem_driver such as "chem_adv_tim" and...

    Data Format Issues Related to .bin Files

    Hi all. I'm using PRE-CHEM-SRC to generate file for WRF following the exercise2(NOAA - Global Systems Laboratory). Unfortunately the convert_emiss can't run well. So I had to write my own Python program to convert the .bin file generated by PRE-CHEM-SRC into the .nc format. However, when I...
