wrf-chem emissions

Hello, I am encountering an issue when restarting a WRF-Chem simulation. The model runs successfully when started or restarted at 00 UTC and 12 UTC. However, when I attempt to restart from 06 UTC or 18 UTC, the model stops with the following error: 0 input_wrf: wrf_get_next_time...

Hi all, I am having a strange problem while running REAL.EXE for my WRF-Chem run. REAL.EXE generates the expected wrfbdy_d01 file but it contains only chemical boundary species; it does not contain meteorological boundary species (e.g., U_BXS, V_BXS etc.). There is no error or warnings and...

Hello, I would like to run WRF-Chem using chem_opt=204 (SAPRC99 chemistry with MOSAIC using the KPP library). I would like to prepare anthropogenic emissions using EDGAR data. However, I currently only have these two mapping files: MOZCART.inp MOZART-MOSAIC.inp I would like to know whether...

hallo friend, i wanna ask if somebody have the same issues and already solve this problem. i run wrf chem on mid latitude area, only 1 domain, i use GFS data as meteorology input, edgar htap mozcart for anthropogenic using chem opt 301, also i use waccm as boundery use mozbc, i already check...

Hi all — I’m seeing a reproducible WRF-Chem/KPP build stop that looks like an internal consistency issue in the CBM4 mechanism files During a WRF-Chem build (`WRF_CHEM=1`, `WRF_KPP=1`), the `chem/KPP/compile_wkc` step iterates over mechanisms and exits with: > `ERROR: variable name for third...

I have setup a WRF-Chem run to simulate smoke over California and while I have created all the wrffirechemi files using the FINN data, the simulation stops after it writes the first file with the error: open_aux_u : error opening auxinput5_d01_2020-09-14_06:00:00 for reading. 100 --------------...

Hello WRF community, I have been reading the WRF Chem Emissions guide that the community was very kind to upload in this forum. I have been trying to access the WRF data files from ftp servers specifically ftp://aftp.fsl.noaa.gov/divisions/taq/emissions_data_2005 link. While navigating ftp has...

Dear all, I’m trying to run a WRF-Chem simulation to study the interaction between dust and ozone. My goal is to simulate both dust emissions and ozone chemistry in the same run and analyze their coupling effects. From previous posts, I’ve seen that it might be possible to activate both by...

Hi all! I am interested in using the tracer_opt = 2 in WRF to eventually model the emissions of a custom aerosol. I have been using WRFv4.7.1 with WPSv4.6.0, but have come across the same error in WRFv4.3.3 with WPSv4.3.1, so I don't believe that it is a version issue. I have been able to...

Hello everyone, I am currently running VPRM on the basis of WRF-Chem V3.9.1.At present, I have successfully used pyVPRM to output the variables required for VPRM such as EVI, LSWI, etc., and write the relevant variables to vprm_input_d01. The variable information and dimensions are as follows ...

Dear all, During WRF-Chem simulations, in addition to accounting for wildfire smoke emissions, is wildfire heat flux considered? If not, how can wildfire heat flux input be added? If yes, how can it be disabled? Kind regards,

I'm using WRF version 4.5 with the PREP-CHEM-SRC 1.5 utility to convert daily emission files for a two-day test case (from 2024-03-15 00:00:00 to 2024-03-16 00:00:00), with outputs every 6 hours (matching my met_em files). I run PREP-CHEM-SRC daily and loop over each day to generate emissions...

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...

Hi, I hope you are doing well. My name is Samira. I am trying to run WRF-Chem in two different months, but continuously. I will be appreciate if you can help me I have one question about running WRF-Chem from 25 January to 10 February (for example, the year 2022, which involves two months) in...

Hi everyone, I'm running into a persistent error when executing ./wrf.exe for a WRF-Chem simulation. The model crashes at the beginning of the run with the following error message: forrtl: severe (66): output statement overflows record, unit -5, file Internal List-Directed Write. From the log...

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...

Hi Everyone I am working with Co2 anthropogeinc edgar dataset by using prep-chem source utility. My issue is that all commands has been successfully executed and after that when i see my wrfout file (by ncview command) then it shows meterological dataset but not showing co2, ch4 etc dataset I...
