Study of air pollution scavenging. Fourteenth progress report
The field experiments were continued to estimate convective storm particulate scavenging efficiency in proximity to the St. Louis, Missouri urban-industrial complex. Complementary studies of the urban aerosol characterization, source strength, and removal processes were also studied. The 1975 field effort shifted emphasis from the immediate St. Louis area to the Alton-Wood River industrial complex. Along with the change in size and configuration of the network, there were increases in the numbers of most types of samplers. The new network yielded the following types of samples for analysis and interpretation: 1065 total rain samples from 85 sites; 68 sequential rainwater samples from 2 locations; 272 wet/dry samples from 7 locations; 216 air filter samples from 7 locations; 36 air filter samples from aircraft; and raindrop spectrometer data from 11 sites for the period 17 June-18 August. The analysis procedures require that all water samples undergo filtering for separate analyses of soluble and insoluble fractions of the elemental concentrations. This data collection effort provided a record number of samples for chemical analysis. Approximately 4000 pibals and over 370 radiosondes were released in the operational period, providing wind and thermodynamic data on 33 days. Aircraft missions were flown on 24 days, with one air tracer release of cesium on 19 July 1975. The status of the analysis of all types of data is described.
