Hi thank you for a great video. I was wondering if you every encountered such error : forrtl: severe (64): input conversion error, unit -5, file Internal Formatted Read. My error files says my wrfchemi file was acceptable to use but keep encountering conversion error.
You mentioned towards the end of video that compile command needs to be run two times for compiling wrf-chem. I didn't understand that. Could you please explain that why it needs to be run twice and any further readings for that?
First compilation is for the main WRF/Chem model by "./compile em_real", and the second compilation is related to the emissions tools (prep_chem_sources, anthro_emiss, ...) by "./compile emi_conv". If you don't need emissions data (e.g. in case of dust modeling), you can ignore the second compilation.
@@amirhosseinnikfal968 Thanks, understood. I did that way. But your wording in tutorial sounded like we have to do compile em_real again after emi_conv. Thanks for explaining.
@@amirhosseinnikfal968please check from 4:00 minutes onwards. You go back to WRF directory and write ./compile and say you need run compile command twice. That created confusion. Anyways, it's all good.
If it's available in an hourly basis (e.g. ERA5 data), you can set it to one hour. But there are some other data, such as GFS data which are based on 3 or 6 hour intervals.
very good. when I compile WPS, I received some errors such as: "fatal error: jasper/jasper.h: No such file or directory 5 | #include "jasper/jasper.h" after I did not have *.exe files in WPS folder. how can I fix it?
Hello sir , This is a great tool, but some how the shaded coutour plot is not working for me while the other is working very fine, its all white all over the area, but the color bar is showing a range, Can you please help with this its very urgent! 🙏
Hi. Thank you again for the tutorials... I have some doubts...I would like to work with FINN database, its is possible? Or only work with GFED? And prep_chem its is only works with emiss_opt=301? Thank you
Hi. Any emissions data can be used. You just need to apply them on the grid points of your domain. emiss_opt for prep_chem is recommended to be 5. If you meant chem_opt, most options are okay with prep_chem If you have very detailed technical questions, please try to use GitHub.
Hi, thank very much for the tutorials.What can i use anthro_emiss for nested domains? could be similar to prep_chem? Also I was trying to use the antro tool, but when i execute ./make_anthro i have this error: Using /usr/bin/gfortran fortran compiler ============================================================================= ============================================================================= netcdf top level directory = /data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install/ ============================================================================= /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include misc_definitions_module.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include constants_module.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include mo_calendar.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include anthro_types.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include mapper_types.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include area_mapper.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include anthro_utils.f90 /usr/bin/gfortran -g -c -I/data/users/ysilva/WRF_CHEM4/WRF/COMPILER_gfortran/netcdf-install//include data_file_utils.f90 data_file_utils.f90:251.132: ind=8) + .5_8*(real(src_lons(nlon_src),kind=8) - real(src_lons(nlon_src-1), 1 Error: Syntax error in argument list at (1) Makefile:40: recipe for target 'data_file_utils.o' failed make: *** [data_file_utils.o] Error 1 Failed to build anthro_emis
For nested domains you need to run the utility for each domain separately. Than is a compiler issue. There is one issue before the installation you must consider before the compilation. I mentioned it in the installation video.
@@amirhosseinnikfal968 Thank you. May I ask you one more question? In the wrf-chem manual,there is a namelist option called 'dmsemis_opt'. I want to set it to 1, but I don't know how to provide dms reference field. Do you have any suggestion?
hello when I am running my model even without chemistry option it is taking too much time and with chem_opt= 301, for d01 approx 300 elapsed seconds , for d02 90 seconds and for d03 10 sec. even to run a 10 day data it is taking ages. I am running on hpc with 36 processors with mpirun -np 36 ./wrf.exe. What could be the reason ?
Do I need the waccm file to be of the same start time as specified in wrf input file? i tried running with waccm of feb 2022 but in my namelist start time is from Dec 2021 and i ran into an error mozbc couldnt read the variables of my wrfinput file. After successfully running of mozbc_input.sh the variable spc_map was empty in mozbc.inp even the wrfinput_vars.txt shows no species it only showsType: float
@@amirhosseinnikfal968 i am running for a whole year, this time period cannot be encompassed in waccm file as , a max of 31 day file can be downloaded. What can I do to solve this?
@@rage4455 You can merge all files to one file representing the whole year. You can use NCO commands. Something like below (all files are appended to file3.nc) ncks -A file1.nc file2.nc file3.nc PS: Please preferably make issues on GitHub if you have technical questions.

Hello, I encountered an issue while using the WRF model to map NH3 pollution. I ran the command "./real.exe" with the parameter "chem_opt=10" to incorporate NH3 into my WRF input file. However, despite successfully running "real.exe" without any errors, I noticed that there are no pollutants present in the WRF input file. Could you please provide guidance or assistance on how to resolve this issue and ensure that the pollutants, specifically NH3, are correctly incorporated into the WRF output? Thank you.
This situation is not totally clear to me. However, try to run real.exe with chem_opt=301, and after making the emissions data (before running wrf.exe), change it to 10.
Event when running `real.exe` with chemistry option 301 enabled. It appears that pollutants aren't being correctly integrated into the `wrfinput` file. And after running `wrf.exe`, the resulting `wrfoutput` file only contains meteorological and geological variables, lacking the expected pollutants. And I am not available to figure out the issue.
What kind of atmospheric data are you trying to ungrib? The available Vtables can support the frequently used ones, including GFS, FNL, and ECMWF (ERA5).
@@amirhosseinnikfal968 I'm currently using CMIP5 future scenarios, which are giving me only intermediate files and the data description is saying not to run ungrib.exe, so should I create an extra Vtable??? Or is it not required at all??
@@tanmoy_sen I am not familiar with CMIP5. However, you can give it a try, according to wolfscie.wordpress.com/2017/05/05/working-with-cmip5-data-in-wrf-1
thank you very much for these tutorials. These videos are helping me a lot to learn the basics in wrf chem. For this tutorial, when i tried to run real.exe, it is telling me that I am missing the met_em_d01 file. Could you please indicate the location of data needed for running wps before real.exe here?
Have you run WPS successfully? If so, the error is self-describing. You need to link the met_em_d0 data from your WPS directory to your WRF run or test directory: ln -s path_to_wps/met_em_d0* path_to_wrf
@@amirhosseinnikfal968 thank you very much for the reply. I missed the WPS part back then. Now I've come over the issue. Thanks again for such helpful tutorials.
Thank you so much, I have WRF with chem and the 3 exe files ( wrf, real, tc) exist in the em_real dir, however, when ,/compile emi_conv I got WARNING: There is no 4D array named emis_ant so whats wrong with it?
Hi. I cannot comment on this issue since I don't have enough information about it. However, if it is a warning message, and if convert_emiss.exe has been generated, you can ignore it. For the next times if you have technical questions, please try to make issues on GitHub. There would be the best place to discuss such issues.

Very nice tutorial, thank you. I have a question. I have retrieved ERA5 data using your codes and tried running my own test case. However, when I run real.exe I get this error: -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 3110 grid%tsk unreasonable Digging into the WRF-ARW forum it may seem related to land_sea_mask variable, but I can see it's requested in your Python code. Any suggestion? Thanks!
Hi. The codes have been tested successfully for many WRF runs, and there is no necessary variable that is missed by them. Maybe the region (lat/lon) you specified in the codes are smaller than your WPS domain (geo file).
Hello, first thanks for the tutorial, I got the same error as mentioned there from @fabiodioguardi5065 (I made sure i have the same region (lat/lon) of my WPS), were you able to find a solution ? @fabiodioguardi5065
