Spectroscopic measurements of the composition and processes in the Earth's atmosphere.

Our activities are mainly centred on the sounding of atmospheric composition from satellites, with our main field of expertise being atmospheric radiative transfer in the infrared. We develop and maintain state-of-the-art RT software, which are used along with inverse methods to retrieve atmospheric trace gas concentrations and aerosol properties. We take an active part to several space missions for the sounding of the low Earth’s Atmosphere (IASI, ACE, GOSAT), and also contribute to the preparation of future programs under auspices of ESA, EUMETSAT and CNES.

Our research is at present deeply connected to the infrared atmospheric sounding interferometer (IASI) mission [1][2]. Concentration distributions of reactive trace gases and aerosols are retrieved routinely from IASI measurements, and examined on various spatial and temporal scales. Applications range from global pollution monitoring (identification and quantification of sources and transport) and the assessment of environmental impacts, to the study of local plume chemistry. They also include several operational aspects, e.g. in air quality forecasting and volcanic surveillance.
