Abstract

Complementing PAN were measurements of NO, O₃, CO, C₂Cl₄, radon, and a variety of other chemical and meteorological parameters. Over the Amazon Basin, PAN was present at a mixing ratio of 5 to 125 ppt. Despite strong local and regional convective activity, a distinct vertical structure with highest mixing ratios aloft was observed. Median PAN mixing ratios of 12, 20, and 48 ppt were present in the 0- to 2-, 2- to 4-, and 4- to 6-km height intervals, respectively. Data collected during the cross-basin flights showed that the PAN mixing ratio was highest over the rain forest and declined eastward toward the Atlantic Ocean. -from Authors
