Hi everyone, I want to perform WRF-Chem simulations with MOSAIC options to study aerosol mass and number concentrations in each bin. The wrfout** file does not contain any aerosol concentration variables. I am wondering if there is errors in the namelist settings (namelist.input) and...

Hi, everyone. Recently I have a question. That is, if I have a gridded dataset of urban building height. How can I use it when I run a WRF simulation? As I know, we re allowed to replace the land use and land cover (LULC) data. Is there a similar way to deal with urban 3D data? Now only...

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...

hello there, i am trying to install wrf chem model, everything goes well when i try to compile, it show this error "Problems building executables, look for errors in the build log" i went to log file and check the error "ERROR: variable name for third body in KPP species file is expected to be...

Hi all, Fairly new WRF-Chem user here. I'm trying to run WRF-Chem with CMBZ/Mosaic over northern Australia, nested simulation with resolutions of 27, 9 and 3 km. I am unable to progress the simulation beyond the first few hours, with persistent SIGTERM errors ( "error (78): process killed...

Hi there, I'm trying to add some variables to my wrfout file. So, added these two lines to my namelist: Also, I defined the variables I wanted in my wrfout in man_output.txt file by adding this line: After running WRF-Chem, I have all the added variables in my wrfout, except for SOA...

Hi Everyone, I compiled the WRFV3.9.1.1 without errors and got the ndown.exe, real.exe. tc.exe and wrf.exe generated successfully. However, in the run/namelist.input, I didn't find the "&chem" block and found nothing about the chemistyr, emissions... Anyone knows how to fix it? The...

Hi, I am using WRF-chem 4.4.1, but while running the wrf.exe, I am getting the following error. Timing for Writing wrfout_d01_2019-11-01_00:00:00 for domain 1: 32.39404 elapsed seconds mediation_integrate: med_read_wrf_chem_emissions: Read emissions for time 2019-11-01_00:00:00...

Hello everyone, I gave a WRF-Chem run of the direct effect using the RADM2-MADE/SORGAM chemistry option. The thing is, the simulation of the parent domain was completed successfully without throwing any errors or warnings. But when I gave a simulation for the nested domain after including...

Hi, I am using WRF-chem 4.4.1, but while running the wrf.exe, I am getting the following error. WRF NUMBER OF TILES = 1 d01 2017-11-01_00:00:00 ---------------------------------------- d01 2017-11-01_00:00:00 W-DAMPING BEGINS AT W-COURANT NUMBER = 1.000000 d01 2017-11-01_00:00:00...

I was following this tutorial for WRF-Chem with volcanic ash simulations (https://ruc.noaa.gov/wrf/wrf-chem/tutorialexercises/tutorialexercises002.html), with slight modifications with the namelist.input and using WRF-Chem 4.4.2. During the conversion of the emission files from PREP-CHEM-SRC-1.5...

Hi all, I am using WRF-Chem v4.4.2 under a triple nested domain (36 km, 6 km, and 1 km) in August 2019. In 6 km and 1km simulations, there is a strange T2 cold bias after several hours of reinitialization. Consequently, simulations crash. I tested different versions of WRF from v4.1.4 to v4.5...

Dear all, I am running WRF-Chem (version 3.9.1.1) using RADM2-MADE/SORGAM, including aqueous reactions (chem_opt=11). I have successfully prepared anthropogenic emission input data from the EDGAR v5 MOZART dataset using anthro_emis, biogenic emission input data from the MEGAN dataset using...

Hi, I just start learning WRF. I wanner repeat the results of this article. "Simulating nuclear cloud rise within a realistic atmosphere using the Weather Research and Forecasting model " I ran WRF4.2 in ubuntu18.04. And, I tried to set up a warm bubble in em_quarter_ss case. Now I want to add...

Hi all, new WRF-Chem user and first time poster. My three day, four nested domain simulation runs for the first 24 h (2023-02-22), then fails to move onto the next day, with the following error. ERROR: Could not find matching time in input file wrfchemi_d01_2023-02-22_00:00:00 It should...

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...

Hello, Everyone. I am using AWS(ec2-user) (WRFv4.2_dmpar) as a platform of WRF, I found it on WRF official website (Cloud WRF), I am not able to locate convert_emiss.exe, all I saw was convert_emiss.F, Kindly guide.

Hello everyone, I want to perform WRF-Chem simulations using the CBMZ-MOSAIC chemistry option to study aerosol-cloud interaction. I want to use anthropogenic emissions from the EDGARv5_MOZART_dataset (from the EDGAR v5.0 emissions inventory speciated for the MOZART chemical mechanism) or...

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...
