wrf-chem emissions

Hi all, I am a new user of WRF-Chem and have several questions related with CBMZ and initialization of the simulation: 1) Can I use prep_chem and/or the programs provided by NCAR to prepare the emissions (bio, anthro) when using the CBMZ chem_opt? 2) Can I use the software mozbc to initialize...

Dear WRF community, For my MSc thesis research I am running WRF-CHEM with emission files I had to create myself. These emission files have the following naming convention: <wrfchemi_d01_yyyy-mm-dd_HH:MM:SS>. This particular WRF-CHEM simulation covers 24-06-2018 up to 01-01-2018, thus running for...

Hello WRF Community, I was wondering if someone could explain the relationship between p_top_request and the ERA5 input data height? I am working on a project that needs to resolve up to the stratosphere and possibly mesosphere and I'm not sure if my p_top_request value needs to change...

Hello everyone, I want to set up the executable file for PREP-CHEM-SRC (prep_chem_sources_RADM_WRF_FIM.exe) to prepare the chemistry input files for running WRF-Chem. For that, I have downloaded the tar.gz file 'prep_chem_sources_v1.5_24aug2015.tar.gz' from the WRF-Chem ftp site...

Hello everyone, I have successfully completed the tutorial exercise for dust-only simulations. Now, I am learning how to use the global emission data sets to make the emissions input file. But I learned that many of the links provided in the WRF-Chem User's Guide and WRF-Chem Emissions Guide are...

Hi everyone! I was running WRF-Chem3.9.1 with KPP, reinitialized the meteorology every 24 hours but with chemistry field from previous time step when doing re-initialization. After running several days, a SIGSEGV occurred (see all_rsl.error.txt attached). Since I found in the error log file...

We would like to evaluate Br emissions from volcanic activity in Air Quality over Mexico City and also effect of Cl from anthropogenic emissions. Does any one have an update WRF-chem code to do it? Thanks in advance

Hi everyone: Can we provide dust emission data using our own data in the anthropogenic-emissions file and run the dust only chem option? Thanks very much!

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...

Hi! I'm a new user of WRF-Chem and I was trying to do exercise 1 of the WRF-Chem tutorial (https://ruc.noaa.gov/wrf/wrf-chem/tutorialexercises/tutorialexercises001.html) but I cannot access to the data needed to run the exercise. Am I the only one with that problem? The namelist is perfectly...

Hi, I am running WRF-Chem v4 with saprc99, and I have some questions as following. 1.If my wrfchemi_00z_d01 and wrfchemi_12z_d01 have ten layers which contains the low, mid and high pollution sources, will the wrf-chem model automatically interpolate these ten layers into the eta_levels...

Hi, I'm using WRF to compute transport of passive greenhouse gas tracers (chem_opt=17, emiss_opt=17). Those are usually expressed as dry air mole fractions, and I assumed WRF does the same. A student's question prompted me to look into this and now I'm not sure whether emissions are actually...

Dear all, I am trying to run WRF-Chem for the first time. I have been running WRF for several years now. I have monthly CAMS global data, and I have no idea how to prepare these files to go into WRF-Chem. I have a file called prep_sources_chem.inp but I am not sure if it's the right one to use...
