Abstract
Nonlinear least squares spectral curve fitting has been used to derive vertical mixing ratio profiles for NO2 and H2O above 16 km from high resolution (∼.02 cm−1) solar spectra collected during sunset with a balloon borne interferometer. The NO2 profile shows a sharp peak of ˜8 ppbv at 32 km falling rapidly to 2O profile shows a broad peak of ˜6.5 ppmv at 30 km falling to <4 ppmv at 17 km.Keywords
