Stratospheric Fourier Transform Spectroscopy

Abstract

For more than 15 years our project in the Atmospheric Chemistry Division of NCAR has flown a Fourier transform spectrometer aboard aircraft to record the infrared absorption spectrum of the stratosphere. These spectra, now totaling more than 45,000, have been used to derive the concentrations of a number of stratospheric gases and to define their latitudinal, seasonal and diurnal variations.
