Description

The data are part of the 2022 Modeling Platform used to support regulatory actions and technical analyses conducted by the EPA's Office of Air Quality Planning and Standards. Specifically, this data includes Weather Research and Forecasting Model (v4.4.2) conducted at a 12-km resolution over the Continental United States (12US). MCIP-processed files and wrfcamx-processed (12US1 domain) are also available as part of this dataset to assist in the use of emissions processing and photochemical modeling. These files may be used in downstream applications to generate emissions, photochemical modeling, or dispersion modeling inputs. Additionally, lateral boundary condition files generated using GEOS-CF at 36-km with results translated from GEOS-Chem species available in GEOS-CF to CMAQ cb6/ae7. Simulations for boundary conditions covering the northern hemisphere are also provided. These simulations were conducted using CMAQ v5.4 and GEOS-Chem v14.0.1. The 2022v1 emissions are provided for a 36km grid over North America (36US3) and two 12km grids (12SU1 and 12US2). See the documentation for pictures of the grids. The types of emissions data provided include point sources, nonpoint sources, mobiles sources, fires, lightning NOx, and biogenic emissions. Input files for computing biogenic emissions inline within CMAQ are also provided. README text files are included at multiple levels within the directory structure to explain files at that level. For more information about the emissions, see the below documentation or the 2022v1 web page: https://www.epa.gov/air-emissions-modeling/2022v1-emissions-modeling-platform

Description

The 2022 WRF output are stored as uncompressed netcdf/hdf5 formatted files in the /WRF directory. The 2022 MCIP output are stored as uncompressed netcdf/hdf5 formatted files in IOAPI format in the /MCIP directory. The wrfcamx files are stored as uncompressed netcdf files in the /wrfcamx directory. Information on the model projection and grid structure is contained in the header information of the netcdf file. The netcdf files can be opened and manipulated using software programs that can read and write netcdf formatted files (e.g. Fortran, R, Python). The WRF files are daily files containing hourly data beginning at 00UTC through 23UTC for each modeled day. For more information: https://www2.mmm.ucar.edu/wrf/users/ The MCIP files are daily files with multiple files for each day. For more information about what each MCIP file contains, please see the following GitHub entry: https://github.com/USEPA/CMAQ/blob/main/PREP/mcip/README.md For more information about what each wrfcamx file contains, please see the README file in the wrfcamx source code file available from Ramboll at: https://www.camx.com/getmedia/wrfcamx_v5.2.10Jan22.tgz The 2022v1 emissions data are stored as uncompressed netcdf files in the /emis directory. The year 2022 CMAQ-ready emissions are provided under the folder 2022hc_cb6_22m
