IASI+GOME2 is the multispectral observation of ozone at the lowermost troposphere and above from synergism of IASI thermal infrared and GOME-2 ultraviolet measurements.

This currently unique approach has been developed at the LISA laboratory (Laboratoire Inter-universitaire des Systèmes Atmosphériques UMR 7583 CNRS/UPEC/UPD), in collaboration with the Harvard-Smithonian Center for Astrophysics (USA), the Karlsruhe Institut für Technologie (Germany) and the Chinese Acadamy of Sciences (China). These innovative satellite observations offer a new potential for analysing ozone pollution from space.

Global IASI+GOME2 data is routinely produced at the AERIS/ESPRI atmospheric data centre. Development, validation and exploitation of the IASI+GOME2 approach is currently supported by the Centre National des Etudes Spatiales (CNES) via the SURVEYOZON project from Terre-Ocean Surface Continentale Atmosphere comitee (TOSCA), the Université Paris Est Créteil (UPEC) and the Centre National de Recherche Scientifique (CNRS).

The IASI+GOME2 product is provided as daily netcdf files with vertical profiles of ozone from the surface up to 60 km of altitude, selected partial ozone columns (including the lowermost troposphere), averaging kernels, error estimations, temperature and pressure profiles, surface temperature, cloud fraction and quality flags, after cloud screening and quality checks.

This IASI+GOME2 metadata and data are currently under achievement. Very soon, it will offer a quicklook browser and direct download of data. For obtaining IASI+GOME2 data, please contact the Principal Investigator of the IASI+GOME2 project, Juan Cuesta, from the LISA laboratory: cuesta@lisa.u-pec.fr
