Abstract
The Illinois State Water Survey hosted a three-week field intercomparison of several sulfate dry deposition measurement techniques during September 81. The site was an 80-acre grass field in a rural area 14 km southwest of Champaign, IL. The vegetation consisted of mixed grasses 25-35 cm high. The experimental techniques used were surrogate surfaces (plates, dishes, and buckets) and eddy correlation for particles containing sulfate. The eddy correlation data are not yet available, so this preliminary intercomparison is restricted to the surrogate surfaces, which were Teflon disks, polycarbonate dishes, Teflon-coated aluminum plates, and HASL dry buckets. Clearly, surrogate surface design and exposure procedure have a major influence on sulfate dry flux collected by the sampler.
