Georgia EPD processed five years (2018-2022) of meteorological data for various combinations of ASOS surface and upper air station pairings.  Georgia EPD assigned station pairings to each county based on distance to the centroid of the county, climatological zone, data collection period, and data completeness criteria.

Georgia EPD processed meteorological files using AERMET (v23132), AERSURFACE (v20060), and AERMINUTE (v15272).  The consecutive five years (2018-2022) of meteorological data were generated with one-minute wind data for all ASOS stations.

A justification of the representativeness of the meteorological data for a specific site location must be provided in the modeling protocol. Download this xls file. View the surface station height information  (both surface and upper air stations). The surface station height is used in AERMOD input as PROFBASE keyword.

For questions on the selection and use of this data, please contact Permit Modeling or call (470) 524-0734.
