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 2016-2020. 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 using AERMET version 19191. Additional meteorological data from alternative sites are available by email request. Ohio EPA is currently processing meteorological data using AERMET 21112 and will make these files available in the near future. Users may contact Ohio EPA if 21112 data is needed prior to this future update.
