Abstract--Measurements of non-methane hydrocarbons, as well as ozone, meteorological and trace gas
data, made at four rural sites located within the southeastern United States as a part of the Southern
Oxidants Study are compared. The C2-Clo hydrocarbons wereobtained during the 1200 1300local time
period,onceeverysix daysfrom September 1992through October 1993.The lightmolecularweightalkanes
(ethane, propane, n-butane, iso-butane, ethene and acetylene) display a seasonal variation of a winter
maximum and summer minimum. Isoprene was virtually non-existent during the winter at all sites, and
