Abstract

The Scanning Imaging Absorption spectroMeter for Atmospheric CHartographY, SCIAMACHY, was proposed in 1988 and was launched in 2002 aboard ENVISAT. It makes measurements of back scattered, reflected, transmitted and emitted electromagnetic radiation in the spectral range between 220 and 2380 nm.

Inversion of the measurements of SCIAMACHY yields three-dimensional information about trace gases, aerosol and clouds. Observations of atmospheric pollution in the troposphere, key constituents in the stratosphere and mesosphere are obtained. For example the following species and parameters are observed - troposphere: trace gases (O3, NO2 HCHO, (CHO)2, CO, SO2, H2O, CH4 and CO2), cloud and aerosol parameters - stratosphere trace gases (O3, H2O, BrO, OClO, NO2), PSC and aerosol - mesosphere: O3, NO emission, OH emission, OH, metal and non metal atomic emissions. In this presentation results and scientific highlights from the first four years of observations of SCIAMACHY will be presented and reviewed.
