Abstract

The mixing ratio profile of N₂O₅ has been inferred from high-resolution emission spectra obtained with a balloon-borne Fourier spectrometer (SIRIS). The observations were taken for the period from midnight to predawn on September 16, 1986 at 32° N latitude. The inferred volume mixing ratio from nighttime average spectra has a peak of ∼ 1.8 × 10⁻⁹ in the 32-35 altitude range. The inferred mixing ratio is generally less than the theoretical predictions from a 1-D model.
