Abstract

Given the present state of the art, remote sensing of vegetation fluorescence from space can be considered as feasible on a technical point of view. However, many unresolved questions remain about its interpretation and its use as a physiological indicator. Low sunsynchronous orbiting satellites are not adapted to capture the highly dynamical variations of vegetation fluorescence under environmental constraints because of their long repeat cycles. However, high frequency observations can be reached by geostationary platforms. We present and discuss here the GFLEX project. Its objective is the use of a multispectral imaging system to assess photosynthesis dynamics as a function of irradiation by observing chlorophyll fluorescence and the photochemical reflectance index from a geostationary orbit. The possibility to merge GFLEX and OCAPI, an ocean colour geostationary project for marine applications is also discussed.
