- Abstract
IASI, an advanced Infrared Fourier Transform spectrometer dedicated to vertical atmospheric sounding was launched on MetOp-A in October 2006. One year after, the first lessons learned on its performances and capabilities are presented. Some of the products are illustrated, showing very promising applications. IASI paves the way to a generation of advanced infrared atmospheric sounders not only for operational meteorology but also for climate studies or air quality monitoring. A new generation of spectrometers is now under study either in the framework of Post EPS in continuation of the MetOp series, for science and demonstration, or for GMES Sentinel 5. SIFTI is one of such instrument designed as an element of the TRopospheric Air Quality (TRAQ) mission selected by ESA as potential candidate for an Earth Explorer mission in the 2013-2014. SIFTI is a static FTS with a high spectral resolution (0.125 cm-1 apodised) specially dedicated to the retrieval of ozone and carbon monoxide profiles. The instrument presently studied in phase A by CNES with Alcatel as prime is presented. A phase 0 study has also started to design the Infrared sounder for the Post EPS mission. Research and Development studies have been initiated to get reduced data rate. The scientific studies made to support SIFTI, Post EPS missions and their early results are presented.
