Southern Oxidant Study (SOS)


Big Meadows Monitoring Site
Shenandoah NP, VA
The SOS Program is a cooperative program including university researchers, state and federal agencies, and private industry. The objectives of this regional program are to better understand photochemical oxidant formation and transport in the southern states and to provide input in the development of effective ozone control strategies. The National Park Service has participated in SOS by the collection of data at two parks with enhanced monitoring stations that were set up with the assistance of the Tennessee Valley Authority (TVA). Great Smoky Mountains National Park has four monitoring stations including enhanced monitoring at Cove Mountain. Mammoth Cave National Park has one enhanced monitoring station.

The following measurements are being made at the two stations: ozone, sulfur dioxide, carbon monoxide, NO, NOy, meteorological parameters, UV radiation, solar radiation, and speciated volatile organic compounds (VOC). Data is available for the summers of 1995 and 1996 plus the winter period between.

Cooperating researchers include the following:

National Park Service: Jim Renfro, Scott Berenti, Bob Carson, John Ray

Tennessee Valley Authority: Bill Parkhurst, Ken Olsynia

University of Miami: Rod Zika
