Paper Abstract

Use of the Barringer Dual-Gas COSPEC II Correlation Spectrometer permits the measurement of total burden or ground-level concentrations of SO2 and NO2 simultaneously. The instrumentation utilizes separate analysis systems to measure the absorption spectra of the two target molecules developed on a single input beam of light. The source of the energy may be either Rayleigh-scattered light from the sky or an artificial source located up to three km distant. Total burdens of NO2 and SO2 measured in traverses over a number of areas demonstrate the horizontal variations in contaminant level. Effluent plume analysis indicates the rate of production of specific stationary sources. The long-line artificial light configuration is sensitive to spatially integrated variations in gas concentration as low as one ppb.
