The Convective Diffusion Observed by Remote Sensors (CONDORS) field experiment conducted at the Boulder Atmospheric Observatory used innovative techniques to obtain three-dimensional mappings of plume concentration fields, chi/Q, of oil fog detected by lidar and ''chaff' detected by Doppler radar. It included extensive meteorological measurements and, in 1983, tracer gases measured at a single sampling arc. Final results from ten hours of elevated and surface release data are summarized here. Many intercomparisons were made. Oil fog chi/Q measured 40m above the arc are mostly in good agreement with SF6 values, except in a few instances with large spacial inhomogeneities over short distances. After a correction scheme was applied to compensate for the effect of its settling speed, chaff integral chidy/Q agreed well with those of oil except in two cases of oil fog ''hot spots''. Mass or frequency distribution vs. azimuth or elevation angle comparisons were made for chaff, oil, and wind, with mostly good agreements. Spacial standard deviations, sigma(y), and sigma(z), of chaff and oil agree overall and are consistent at short range with velocity standard deviations sigma(v) and sigma(w) almost-equal-to 0.6w* (the convective scale velocity), as measured at z > 100m. Surface release sigma(y), is enhanced up to 60% at small x, consistent with the Prairie Grass measurements and with larger sigma(v) and reduced wind speed measured near the surface. Decreased sigma(y) at small dimensionless average times is Iso noted. Finally, convectively scaled integral chidy, C(y), were plotted versus dimensionless x and z for oil, chaff, and corrected chaff for each 30-60 min period. Aggregated CONDORS C(y) fields compare well with laboratory tank and LES numerical simulations; surface-released oil fog compares especially well with the tank experiments. However. large deviations from the norm occurred in individual averaging periods; these deviations correlated strongly with anomalies in measured w distributions.
