Retrievals for the atmospheric chemistry experiment Fourier-transform spectrometer

Abstract

SCISAT-1, also known as the Atmospheric Chemistry Experiment, is a satellite mission for remote sensing of the Earth's atmosphere, launched on 12 August 2003. The primary instrument on the satellite is a 0.02 cm-1 resolution Fourier-transform spectrometer operating in the mid-IR (750-4400 cm-1). We describe the approach developed for the retrieval of atmospheric temperature and pressure from the troposphere to the lower thermosphere as well as the strategy for the retrievals of volume-mixing ratio profiles of atmospheric species. © 2005 Optical Society of America.
