Zusammenfassung
To improve our knowledge of the coupling of atmospheric circulation, composition and regional climate, and to provide the urgently needed observations of long-term changes in the middle atmosphere, the Changing-Atmosphere Infra-Red Tomography Explorer (CAIRT) is one of four mission concepts down-selected by the European Space Agency (ESA) for competitive pre-feasibility studies, vying for implementation as the next Earth Explorer satellite mission. As a Fourier transform infrared limb imager, CAIRT will observe simultaneously from the middle troposphere to the lower thermosphere at high spectral resolution and with unprecedented horizontal and vertical resolution (with a goal of 50×50×1 km globally). With this, CAIRT will provide new and critical information on (a) atmospheric gravity waves, circulation and mixing, (b) coupling with the upper atmosphere, solar variability and space weather and, (c) aerosols and pollutants in the upper troposphere and lower stratosphere. In this presentation we will give an overview of CAIRT’s science goals and the expected mission performance, based on latest results from early mission definition studies.
