The data are hourly outputs from the Weather Research and Forecasting (WRF) model generated by the EPA's Office of State Air Partnerships (OSAP), Air Quality Assessment Division, Air Quality Modeling Branch. These data were generated at a 12-km resolution over the Continental United States (12US), beginning for the year 2021 and continuing annually through 2023. These files are intended for use in a broad range of air quality applications, but specifically may be used in dispersion modeling applications that would benefit from the use of the Mesoscale Model Interface (MMIF) tool (https://www.epa.gov/scram/air-quality-dispersion-modeling-related-model-support-programs#mmif) which translates prognostic meteorological data into formats suitable for use with AERMOD, CALPUFF, or SCICHEM. The individual files are less than 1GB in size, which allows for the use of the MMIF tool in a Windows environment. These data are anticipated to be updated annually so the 3 most-recent years are av[...]

The individual files are less than 1GB in size, which allows for the use of the MMIF tool in a Windows environment. These data are anticipated to be updated annually so the 3 most-recent years are available for use. Additionally, model-observation paired files are included to aid in the performance evaluation that is necessary for use of these data in regulatory applications per Appendix W to 40 CFR Part 51.
