AERMET Output Files for AERMOD Model Input

This meteorological data is used to predict maximum modeled concentrations for New Source Review and Prevention of Significant Deterioration air quality modeling. This meteorological data has been processed for use in the AERMOD modeling program. Ohio EPA assigns meteorological data by county, as described in Ohio Engineering Guide #69. All meteorological surface data is derived from 1-hour integrated surface hourly data and one-minute ASOS data (DSI-6405) from the National Weather Service for years 2013-2017 (except as noted below). The meteorological data was processed June 2018, using version 18018 of AERMET, version 15272 of AERMINUTE and version 13016 of AERSURFACE, with a 0.5 m/s calm wind cutoff. Surface characteristics were determine for 12 sectors on a monthly basis, and monthly Bowen ratios were determined from the most recent 30-year precipitation normals for each surface station. All meteorological data was processed with the ‘‘ADJ_U*’’ option. Additional meteorological data from alternative sites are available by email request.
