This paper presents the Geostationary Fourier Imaging Spectrometer (GeoFIS), a new satellite instrument that has been proposed to monitor tropospheric key pollutants (O3, CO) in order to improve the predictive capability of tropospheric chemistry models. The horizontal resolution of GeoFIS is about and the temporal resolution is about 60 minutes. It is shown that the current instrument concept (based on available or under development optical, detector and platform technologies) is sufficient to provide tropospheric concentrations of O3 and CO as well as columns of species like PAN with the required accuracies.
Dans cet article nous présentons le « Geostationary Fourier Imaging Spectrometer » (GeoFIS), un nouvel instrument satellite qui a été proposé pour surveiller les polluants troposphériques les plus importants (O3, CO) afin d'améliorer la précision des prédictions fournies par les modèles de la chimie troposphérique. La résolution horizontale de GeoFIS est de environ et la résolution temporelle est de 60 minutes. Nous montrons que le concept actuel de cet instrument (basé sur des technologies optiques, détecteur et plateforme disponibles ou en développement) est bien adapté pour fournir des concentrations troposphériques d'O3 et de CO, ainsi que des colonnes d'espèces comme le PAN, avec les précisions requises.
