Abstract

The concentrations of sulfur dioxide (SO2), particulate sulphate (SO42-) and other trace gases, as well as meteorological and position parameters were measured from an instrumented aircraft over the south-central United States. Research flights were performed from Little Rock, Arkansas, along a north-south track near the 91.5°W meridian between 29° and 41°N latitude, at constant altitudes of 1700 and 2600 m above sea level. The measurements were carried out during 1987 and totalled about 24 h of air-sampling flight time during each of the four seasons. The average concentrations of SO2 ranged from 1.6 to 6.8 μg m-3 at the lower elevation and from 0.5 to 2.4 μg m-3 at the higher elevation. Particulate sulfate ranged from 1.3 to 3.2 μg m-3 at the lower elevation and 0.5 to 1.7 μg m-3 at the higher elevation. Both SO2 and particulate SO42- concentrations peaked during the summer measurements. -from Authors
