EPA Hourly Prognostic Meteorological Data
3+
Description: >-
4+
The data are hourly outputs from the Weather Research and Forecasting (WRF) model
5+
generated by the EPA's Office of Air Quality Planning and Standards, Air Quality
6+
Assessment Division, Air Quality Modeling Group. These data were generated at a 12-km
7+
resolution over the Continental United States (12US), beginning for the year 2021 and
8+
continuing annually through 2023. These files are intended for use in a broad range of
9+
air quality applications, but specifically may be used in dispersion modeling applications
10+
that would benefit from the use of the Mesoscale Model Interface (MMIF) tool
11+
(https://www.epa.gov/scram/air-quality-dispersion-modeling-related-model-support-programs#mmif)
12+
which translates prognostic meteorological data into formats suitable for use with AERMOD,
13+
CALPUFF, or SCICHEM. The individual files are less than 1GB in size, which allows for
14+
the use of the MMIF tool in a Windows environment. These data are anticipated to be updated
15+
annually so the 3 most-recent years are available for use. Additionally, model-observation
16+
paired files are included to aid in the performance evaluation that is necessary for use
17+
of these data in regulatory applications per Appendix W to 40 CFR Part 51.

The WRF output are stored as uncompressed netcdf/hdf5 formatted files in
44+
directories corresponding to the specific years of interest. The model-obs
45+
paired files are stored as comma-delimited files in the year-specific
46+
directories.
