The report describes the second year of a continuing study to determine the distribution and fate of nitrogen oxides in the atmosphere. Analytical methods developed in the first year were refined and validated and results from the first year study were reexamined with the aid of additional data collected simultaneously by other research groups. An instrumental technique for nitric acid was refined, tested for interference, and verified against a long-path infra-red technique under simulated smog conditions. The interference by PAN and nitric acid with the chemiluminescent determination of NO2 was studied with a view toward reducing or minimizing the interference. Nitric acid interference was eliminated by the use of a nylon prefilter on the chemiluminescent instrument. The interaction of gaseous nitric acid with alkaline glass-fiber filters was shown to yield artifact particulate nitrate.
