Georgia AERMET Meteorological Data

GA EPD processed two sets of five years (2013-2017 with and without adjusted surface friction velocity U* option) of meteorological data for fifteen pairs of NWS ASOS surface and upper air stations.  Assignment of station pairings to each county was based on distance to the centroid of the county, climatological zone, data collection period, and data completeness criteria.

The meteorological files were processed using AERMET (v18081), AERSURFACE (v13016), and AERMINUTE (v15272).  One-minute meteorological data (TD-6405 format) are available for most ASOS stations during 2013-2017, except six ASOS stations during June-December, 2013, and one ASOS station (Valdosta - KVLD) for the entire year 2015. The six ASOS stations are KVPC (Cartersville), KRMG (Rome), KFFC (Peachtree City-Falcon Field), KGVL (Gainesville), KDNL (Augusta), and KSSI (Brunswick).  The missing one-minute data at these sites was filled with 5-minute meteorological data (TD-6401 format). The 2015 meteorological data at Valdosta (KVLD) was generated without 1-minute meteorological data.

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