The published paper presents the results of an SF6 tracer release procedure to quantitatively determine the isoprene emission flux for an isolated oak forest in Goldendale, Washington. The paper presents experimental design development to effectively deploy tracer release sites within the forested area to simulate the natural vegetation release. The downwind sample collection program was designed to evaluate several mathematical approaches to calculate isoprene emission flux. The results presented indicate good comparability between the mathematical models and a bag enclosure technique which was also used for isoprene emission flux measurement.
