摘要
Vertical profiles of stratospheric ozone number density derived from optical spectrograph and infrared imager system (OSIRIS) measurements of limb-scattered sunlight are presented. Ozone profiles are inferred using a method based on the analysis of normalised and paired limb radiance profiles at a set of wavelengths covering the Chappuis-Wulf bands of ozone, and using differential optical absorption spectroscopy (DOAS) in the Chappuis region. Both methods incorporate the pseudo-spherical multiple scattering radiative transfer model LIMBTRAN and an optimal estimation (OE) approach. The results of both methods are compared with ozone sonde and other satellite measurements. (C) 2004 COSPAR. Published by Elsevier Ltd. All rights reserved.
