For the examples for China provided here, we are using GRIB2 NCEP FNL Operational Model Global Tropospheric Analyses, continuing from July 1999 (http://dx.doi.org/10.5065/D6M043C6). {"serverDuration": 96, "requestCorrelationId": "171c3461e7313f96"}, http://www2.mmm.ucar.edu/wrf/users/download/get_source.html, https://ruc.noaa.gov/wrf/wrf-chem/Users_guide.pdf, https://ruc.noaa.gov/wrf/wrf-chem/Emission_guide.pdf, https://ruc.noaa.gov/wrf/wrf-chem/wrf_tutorial_nepal/talks/Setup.pdf, http://www2.mmm.ucar.edu/wrf/src/WPSV3.6.1.TAR.gz, http://www2.mmm.ucar.edu/wrf/src/WRFV3.6.1.TAR.gz, http://www2.mmm.ucar.edu/wrf/src/WRFV3-Chem-3.6.1.TAR.gz, http://stilt-model.org/index.php/Main/HomePage, https://www.acom.ucar.edu/wrf-chem/download.shtml, https://www.acom.ucar.edu/wrf-chem/mozart.shtml, https://www2.acom.ucar.edu/wrf-chem/wrf-chem-tools-community, https://www.ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml, https://docs.google.com/document/d/1Jls4FlWIOIhMlCzMPWm6_aBZqx_Axxe8RMcKjdILDFg/, http://www2.mmm.ucar.edu/wrf/users/docs/technote/, https://www2.cisl.ucar.edu/software/community-models/optimizing-wrf-performance, http://www2.mmm.ucar.edu/wrf/users/cheyenne-note.html, If you're going to be using WRF meteorology output to drive the STILT LPDM (. Check that you have the preferred path set to your WRFOUT directory (recommend regal or some scratch space with a lot of space) in your history_outname field. If you are running WRF without chemistry, you can go ahead and run the main WRF model at this point. ), squeue -u username #monitor your job status. But it also appears to be more straightforward to use, if you aren't rigid about your emissions inventory choice (i.e., if EDGAR-HTAP is sufficient for your purposes). #(1)-(8) are adapted from p.6 of Plamen's advice for v3.9.1 (6/8/2018). Check out the contents with ncview. #(6) Compile WRF before WPS!! Otherwise you can use the compiled version located at: #(13) MEGAN bio emissions. inappropriate choices in the WRF-Chem namelist.input file.

For example, start with the one about how to open and read netcdf files and go from there: If you use ncview, you can quickly get a sense of how your simulation worked. WRF has a bunch of Vtables already in the Variable_Table subfolder of ungrib, but sometimes you will need to do some sleuthing and download the one that you actually need into the Variable_Tables folder. Create WRF-chem emission files using information from the WRF initial condictions (wrfinput) file(s). The PM2.5 values are unrealistic – two orders of magnitude lower than observations in the d03 domain – and this is most likely due to some combination of the following: Accounting only for primary PM2.5. Examine the run_real.log file. Edit the namelist.wps file, specifically: First link your met files from metgrid.exe. "Fully coupled 'online' chemistry within the WRF model." The initial files are based on MOZART 4-GEOS 5 output (6hr, 1.9x2.5deg, 56-level) datasets (https://www.acom.ucar.edu/wrf-chem/mozart.shtml). Define model domains with geogrid. Link your bio and anthro files to your WRFV3/test/em_real/ directory. Each WRF-chem species listed below is actually 2 variables, for emissions into the Aitken and the accumulation size mode respectively. View domain configuration, confirm it's correct. 8. The following is a series of recommendations physics o= ptions thus far identified when using WRf-Chem version 3.2.1 with Crimech g= as phase chemistry and Mosaic aerosol (chem_opt =3D 401). The model ran successfully without chemistry and for convert_emiss.exe. WRF-Chem run using MOZCART failed: Chin-An Lin: 10/21/20: application called MPI_Abort error: Akinyoola Julius: 10/20/20: Short wave and long wave fluxes: Anahita Amiri Farahani: 10/15/20: Take a look at the namelist and confirm the dates and domain match your wps namelist. Link the EDGAR_HTAP_emi_PM2.5_2010.0.1x0.1.nc file from the anthro_data/MOZCART folder to this folder, ln -sf yourpath_toWRF/anthro_data/MOZCART/. PROGRAM METGRID: horizontally interpolate ungribbed met data onto geogrid domains. Make sure you've emptied any files from previous runs in the dump dirs. In your mozbc directory type: Navigate back to your WRFV3/test/em_real directory. [primary reference for first version of WRF-Chem] Output is provided every 6 hours. Make sure to turn off chemistry (chem_opt = 0) for this step. You should have your relevant chem data in WRFV3/test/em_real at this point, ready for ingestion by the wrf model. Note 2: With the exception of the geography data set which is really big, copy the WRF_CHEM_3-6-1 folder to a location you are going to run it from. Run real.exe again. In these examples, we will go this route. Make sure you have the following files output from this step: 5. 9. Otherwise you can link to the already downloaded version: Now that you have a compiled version of WRF and WPS, you are ready to set up your model runs. Soft link to the geography data set in the $CLIMATE_MODELS folder.. #(4) Choose 15. &CONTROL anthro_dir = '/n/holylfs/LABS/kuang_lab/adayalu/WRF/ANTHRO/src' domains = 3 wrf_dir = '/n/holylfs/LABS/kuang_lab/adayalu/WRF/UTILINP' src_file_prefix = 'EDGAR_HTAP_emi_' src_file_suffix = '_2010.0.1x0.1.nc' src_names = 'PM2.5(1)' sub_categories = 'emis_tot' serial_output = .false. #note: be aware of 90-day retention policy of scratch data. If you're not interested in WRF-Chem, and wanted to do a plain WRF tutorial there are much better ones online, or you could just follow along here and skip steps 3 to 6. Referring to the WRF-Chem user manual for more details. This chemistry option uses the CBMZ chemical mechanism and MOSAIC using 8 sectional aerosol bins. Instructions to link to them are noted where necessary. If you are planning to drive an LPDM like STILT with these met files, these need to eventually be converted to .arl format using WRF2ARL directory contents. (Read the README file for details if you want to compile your own version.

These are your WPS final output files that real.exe ingests. This will be your namelist file. They MUST be in this directory in some form. Read the README file for compilation instructions if you're doing this on your own; on the Harvard cluster you might have to do the following: export NETCDF_DIR=$NETCDF_HOME before compilation, and same with MEGAN instructions (#13 below). This is constructed based on a hybrid of following instructions in the README file and the input file located in the anthro_data/EDGAR-HTAP/INP-Examples folder. A compiled version is located at the path below. Note that with the exception of the geog_data_path, all path variables should point to a writable dump directory of your choice. Note that the src_file_prefix and src_file suffix are concatenated with whatever is specified in src_names (here, PM2.5) to generate the full filename string. Make sure you understand the purpose of the entries. There are other packages developed at NCAR for analyzing and visualizing WRF-ARW data: wrf-python - A Python package that extends the functionality of wrf_user_getvar. â Questions: Send email to WRF-Chem help ⦠Jan, QNDROPSOURCE is one of the arrays associated with the cloud-aerosol interactions that our team at PNNL have added. wrf-chem-run Welcome to the WRF-Chem Run discussion group. Step 1a. WRF-Chem ⢠It is assumed that the user of WRF-Chem : â is very familiarwith the WRF model system â have run WPS and a weather simulation using WRFV3 â know FORTRAN and C and can edit code, recompile, etc. For wrf-chem, it's good practice to create a folder for use with various external utilities that you link your intermediate wrf files to. Atmospheric Chemistry Division: WRF-Chem. Take a look at the PM2.5_DRY variable (3D Vars). Now get ready to run ungrib. Thanks to Meng Gao at Harvard China Project and Thomas Lauvaux at PSU for help with this and for providing their WRF-Chem namelist templates for this example! This page documents the steps to run WRF and WRF-Chem on Harvard cluster. Make sure things look reasonable. Step 1b. Edit the prep_chem_sources.inp namelist file. It is recommended you write to regal or a similar scratch space you have access to; the dump files take up space and aren't needed again after the run so they don't have to be stored in a permanent location. It appears that it's useful for very specific data sets (like EDGAR-HTAP). 6. in MADE (Ackermann et al., 1998). Once this is done, navigate to your geogrid dump folder that you specified in your namelist.wps file and visualize the three geo_em..nc files using ncview. I liked to keep my frames hourly (a file is written out every simulation hour. Details: WRF/Chem User's Guide 3.1. In any case, this exercise should at least get you familiarity with the process of running WRF-Chem and set you up for being able to do second-order troubleshooting (like the more important question of why these values are unrealistic!). This will become clearer, but for now make sure you have a directory in your $CLIMATE_MODELS location that's entitled "UTILINP". Create a new text file called anthro_emis.inp. Note: there are other options, like fire emissions ... you need to figure out what is relevant to your question. Make sure kemit=1 (vertical levels in anthro emissions files...in this case it is 1...surface data). Navigate to the MEGAN directory in the $CLIMATE_MODELS directory (or wherever you have saved your local copy of everything), You should be ready to run the MEGAN bio emission utility. #(14) EDGAR-HTAP anthropogenic chemical fields, for use with anthro_emiss utility. Make sure your NETCDF_DIR variable is set if so, and make sure your make_util file is executable. How to Run? 3. wrfinput_ #your standard initialization file from real.exe. WRF-Chem is the Weather Research and Forecasting (WRF) model coupled with Chemistry. Check that the tail of the rsl.error.0000 file says "SUCCESS COMPLETE REAL_EM INIT", This step modifies the wrf initial and boundary condition files that now have space for chemical data (since we re-ran real.exe with chem_opt on and anthro/bio fields). But – since we are running WRF-Chem – we need to run the additional utilities that either use the info contained in these files to map chemical data correctly (e.g., prep-chem-src) or modify the contents directly (e.g., mozbc for inputs of chemical boundary conditions into wrfbdy_d01). You will need to figure out the initialization data set best suited to your domain and purposes. T1_MOZCART presents an update to the MOZART-4 chemical gas phase mechanism in chem_opt 112 (MOZCART; Emmons et al., 2010). Run convert_emiss.exe to convert the chemistry data from binary intermediate to WRF input form. The current recom= mended physics parameterisations for running the UK domain in summer are as= follows (for set ⦠How to Compile? Read the README file in the parent WPS folder for a quick guide on what the programs do. 4. Navigate to your WRFV3/test/em_real/ directory. This is the only step that has significant benefit from running in parallel! Atmos. !IROUTINE: radiation_driver - interface ⦠Navigate to your WRFV3 folder and type: If compilation was successful, you should see convert_emiss.exe in the WRFV3/chem folder. The official repository for the Weather Research and Forecasting (WRF) model - wrf-model/WRF At command line: #Execute real.exe ; no real benefit to running as a parallel job so…. Register in http://www2.mmm.ucar.edu/wrf/users/download/get_source.html. These are your WPS final output files that real.exe ingests. MOZART-4 results for a subset of the globe and a range of dates can be downloaded from this page. Up to you.). You don't need to copy the geography data set. If you are starting with other emissions, you probably need to go the prep-chem route. If you are running WRF-Chem, this is the point at which you run your chemistry data prep program (i.e., prep-chem-src, anthro_emis, and/or convert_emiss) which requires wrfinput_d0* files to actually work. We invite Archana Dayalu, Packard Chan, Lee Miller and Jiahua Guo to co-edit this page. Run metgrid and make sure you get the "successful completion" message. Check that the tail of the file says SUCCESS COMPLETE REAL_EM INIT. You will notice that while the run completed successfully from a technical standpoint, it's actually way off. And due to this dependence upon WRF, it is assumed that anyone choosing to use WRF-Chem is very familiar with the set-up and use of the basic WRF model. While the wrfchemi, wrfbiochemi, and mozbc utilities seem to have gone through, it may not have done so correctly based on an inappropriate namelist parameter selection. Now that you have your bio emissions, it's time to get your anthropogenic emissions in the right format. Like prep-chem, this is another (possibly less versatile) option for getting your anthropogenic chemical fields the wrf-chem format. [...etc for other variables, domains ...]. Note that you have to do this each time you run ./configure, because the configure.wrf script is overwritten each time. Run real.exe to output the necessary intermediate files for chem data processing. Instructions in this part assume you want to compile and run your own version of WRF. Once you are done with this and have all your requisite chem data in the right format stored or linked in the WRFV3/test/em_real folder, you can run the wrf.exe model. (25% to nearly 40% of PM2.5 in many cities in the region is secondary inorganic.). The WRF User's Forum. Presently, the WRF-Chem model is now released as part of the Weather Research and Forecasting (WRF) modeling package. Environ., 39:6957-6976. Link the metgrid files to the test/em_real directory and make sure the namelist num_metgrid_levels and num_metgrid_soil_levels match what's in the metgrid files.
