Overview of the oxidation and scavenging characteristics of April rains (OSCAR) experiment
The OSCAR (Oxidation and Scavenging Characteristics of April Rains) field experiment was conducted in April, 1981, as part of the MAP3S/RAINE program. The OSCAR study was designed to provide detailed characterizations of the physicochemical and dynamical features of selected cyclonic storm systems as they traversed the eastern U.S. Major experiment components included sequential precipitation chemistry measurements, aircraft measurements both in cloud and in clear air in storm inflow regions, surface-level air chemistry measurements, and supporting meteorological measurements. The precipitation chemisty network consisted of an intermediate-density network with 37 sampling sites covering the region from southern Ontario to Tennessee and from Illinois to New Hampshire, and a high-density network with 47 sampling sites located in a 100 by 100 km area in northeast Indiana. A total of four storm events were studied during the experiment. The report describes the design and operational aspects for the high-density and intermediate-density components of the experiment, and the composition of the integrated OSCAR data set which has been developed. A synoptic meteorological description of the four storm events studied during OSCAR is also provided. 17 references, 13 figures, 8 tables.
