Abstract

One of the requirements for a better understanding of stratospheric chemistry is a better data base of stratospheric trace gas measurements. In particular simultaneous measurements of reactive species in the same air mass, which would provide good tests of current models, are almost non-existant. We have built a tunable diode laser absorption spectrometer (TDLAS) capable of making truly simultaneous concentration measurements of more than one species from a balloon platform. At present it is configured to measure NO and NO2 although it can be upgraded to measure the concentrations of 4 species simultaneously.
