A system to study the gas and particle phase products from gas phase hydrocarbon oxidation is described. It consists of a gas phase photochemical flow reactor followed by a diffusion membrane denuder to remove gases from the reacted products, or a fi

A new lightweight NO2 instrument that can be flown from a tethered balloon to give vertical NO2 profiles is described. The detection principle is the chemiluminescent reaction between NO2 and a solution of luminol. The instrument is integrated with a

A pulse dilution system in which small volumes of gas are injected into an air flow, by means of a standard 6-port G. C. valve, is described. This system is shown to produce the expected dilution, and to be able to produce gas mixtures whose concentr

The source strength of atmospheric trace gases from natural ecosystems must be quantified in order to assess the effect of such inputs on the background tropospheric chemistry. A static chamber technique and a gas exchange technique were used to dete

The altitude distribution of NO was measured between 12 and 33 km near 54oN during the stratospheric warming of February, 1979. The NO mixing ratios were considerably smaller com- pared to summer conditions, especially below 23 km. The measurements a

Measurements of NO, NO2, HNO3, O3, N2O, CCl3F, H2O, CH4 and aerosol were made during balloon flights in the stratosphere over Australia at 23°S and 34°S from March to October 1979. These data and ground-based column density measurements of O3 and N
