wrf-chem

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...

I am using WRF-Chem V4.5 to quantify dust-induced changes in radiative fluxes during a June 2024 dust event by comparing dust-on and dust-off simulations. The simulation uses two nested domains, and the chemistry setup is based on the simple GOCART option: chem_opt = 300, 300 The problem is...

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...

Hi everyone, I am encountering a persistent segmentation fault when attempting to run a coupled simulation with both the chemistry module and the Urban Canopy Model (UCM) enabled in WRF-Chem v4.5. Here are the details of my configuration and the testing I've done: 1. The Issue: The model...

Dear all, I am trying to run WRF-Chem with WRF-4.1.1, but I got segmentation fault like rsl.error.0000. I found that when I change the ra_lw_physics and ra_sw_physics, WRF-Chem goes wrong. And sf_sfclay_physics should be 91 or it goes wrong when it was set to 1. The other scheme is OK, but once...

Hello everyone, I face some issue when compiling WRF-CHEM 4.7.1 with I guess a linking error. With WRF-CHEM=0 it works well but with WRF-CHEM=1 and WRF-KPP=1I get: time mpif90 -o ndown.exe -O2 -ftree-vectorize -funroll-loops -w -ffree-form -ffree-line-length-none -fconvert=big-endian...

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...

I am currently using WRF-chem4.6, and my chemical mechanism employs chem_opt=2, which corresponds to RADM2 chemical mechanism and MADE/SORGAM aerosols. In the wrfout file I generated, there is a variable named "PM2_5_DRY". Can this variable represent the total concentration of PM2.5? Or should I...

Hello, I would like to ask whether the options dust_opt and seas_opt are available and actively supported for the RACM-MADE-VBS chemical mechanism (chem_opt = 108). Could you please let me know if these two options are functional for this scheme? Thank you very much for your help. Best...

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 everybody, I am running WRFv4.7.0 with LCZ,(setting use_wudapt_lcz = 1)， But the model crashed or was killed halfway through the run. I set a double nest, only one wrfoutd01 file was output, and I read the content and found that the chemical concentration in it is 0, I didn't see a...

Hello. I am just curious so I am posting here because WRF-Model forum seems to have more replies. I am a new member, and I have posted many questions in WRF-CHEM community. But none of them have been replied to. I am not complaining, just curious. Because I have gotten more replies in WRF-MODEL...

Hello WRF-CHEM community, I have been trying to embed satellite aerosol data into WRF for simulating microphysical processes with real data. So far I have learned: 1. Microphysical schemes either have a built in or a prognostic algorithm for calculating CCN. They have default aerosol...

Hello everyone, I am an MSc student attempting to run WRF-Chem 4.3.3 with indirect effects enabled, in order to investigate the effects of cloud seeding on atmospheric processes. My configuration uses the Morrison 2-Moment microphysics scheme (mp_physics = 10) and RADM2/SORGAM chemistry with...

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...
