Pre-processed, NWS Meteorological Data Sets, 2015-2019
(For use in AERMOD in South Carolina)

The state has been divided into 12 areas such that the meteorological station/data assigned to each area is deemed by SCDES's Bureau of Air Quality (BAQ) to be the most representative, in general, for AERMOD modeling purposes for that area and should be used as the default data for a given area. Please contact BAQ with any questions/issues or unusual circumstances. For PSD permit modeling, the choice of meteorological data should be discussed with BAQ prior to modeling.

Important Note (September 2, 2021)

The meteorological data sets were updated on September 2, 2021. They were processed with AERMET version 21112 and are based on 2015-2019 surface and upper air observations. The data sets should be used for all non-prevention of Significant Deterioration (non-PSD) AERMOD modeling conducted after September 2, 2021. Applicants performing modeling for a PSD permit should contact Greg Quina (803-898-4074) to discuss the AERMET files that should be used for that modeling.

1 - north of 33.74°N
2 - south of 33.74°N

Disclaimer: The meteorological (AERMET) data provided by BAQ is intended to be used for regulatory AERMOD modeling analyses for sources located in South Carolina. These data are periodically updated, so the user should ensure they have the most current data set before modeling. Please contact Greg Quina (803-898-4074) should you have any questions about the use of these data sets.

Digital Terrain Data: National Elevation Dataset (NED) for use with AERMOD

This NED data covering South Carolina was obtained from the United States Geological Survey (USGS). They are made available here for use with regulatory AERMOD modeling analyses for sources located in South Carolina. The data is in county divisions at 1 arc-second (approximately 30-meter) horizontal resolution in GeoTIFF format.

Please note that these data sources may occasionally be updated by USGS. The NED data sources on this webpage were last updated on November 9, 2022. If you have questions about these data sources, please contact the BAQ modeling section at (803) 898-4074.
