wrf-chem

I met a problem when compiling WRF-Chem on Cheyenne. There are some errors when compiling WRFV3.6.1 with Chem3.5.1. The log file is attached named compile.log.zjm. The other one is configure.wrf. BTW, I have succeeded to compile WRFV4.2 with chemistry before, so I guess it seems like a problem...

Hello,everyone! I read an article (Importance of reactive halogens in the tropical marine atmosphere: a regional modelling study using WRF-Chem) which used WRF-Chem to model the halogens and said MOZART-4 mechanism has been extended to include bromine, chlorine and iodine chemistry. Then I...

Dear all, I have been stacked on this problem for half a year, I am gateful that if someone could help me solve this problem. My situation is that the WRF-Chem V3.9.1.1 is always stopped after photolysis driver (rsl.error.000?) and it also happens in latest version (WRF-Chem V4.5.1). The stop...

Hello everyone! I just finished compiling wrf-chem and I'd like to know if it provides downloadable input and output examples? Just like wrf-cmaq in this URL: https://www.epa.gov/cmaq/cmaq-inputs-and-test-case-data Let me test if it works successfully. In fact, I pay attention to the output of...

Hello, I am currently engaged in a comprehensive inquiry into the methodology employed by WRF-Chem for SOA (Secondary Organic Aerosol) calculations. In my current configuration, I have MOSIAC integrated with MOZART, utilizing the chem_opt parameter set to 201, corresponding to...

Dear all, I have a small query regarding the computation of the perturbation in atmospheric variables due to aerosol-cloud interaction (ACI) using the WRF-Chem model. In the case of aerosol-radiation interaction (ARI), the perturbation in atmospheric parameters can be computed by taking the...

Dear all, I am running WRF-Chem-3.8.1 with chem_opt=9. I have been running WRF since 0:00 on July 15, 2016. Everything was fine at first, but by 17:00 on July 17, there were no wrfout files generated and everything seemed to be stuck. But I looked at the log file and there was nothing...

i wonder why this happens ?how can i solve this problems? namelist.input is below. thank you very much!

after finishing DUST1,there is “ncview wrfinput_d01”，but in my view has not sufficient variable.l really wanna know why?anbody can help me?(sorry,my engish is not good) thank you very much!

Dear all, I used the Goddard scheme for SW Radiation and the RRTMG scheme for LW Radiation while running WRF-Chem using RADM2-MADE/SORGAM chemistry options. I want to calculate the net SW radiative flux in the atmosphere using this formula:ΔFatm = ΔFTOA - ΔFsurf However, I noticed that only the...

Hi everyone, I want to convert cam-chem dataset to WRF-Chem's initial and boundary fields following saprc99 chemical mechanism, but there is no saprc99.inp in mozbc. I already knew that cam-chem dataset following mozart mechanism, here is VOC species mapping between MOZART and saprc99 mechanism...

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...

We have a few positions at IIT Bombay that we seek to fill quite urgently under a newly funded project (PAVITRA—Air Pollution Management and Intervention Tool for India). Please see the job profile, and interested candidates may kindly apply through the below link: 1. Project Research...

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...
