The Medium Resolution Imaging Spectrometer (MERIS), developed by the European Space Agency (ESA) for the Envisat polar orbit Earth mission, belongs to a new generation of ocean colour sensors which will yield a major improvement in the knowledge of such a crucial processes as the ocean contribution to the carbon cycle. The global mission of MERIS will have a major contribution to scientific projects which seek to understand the role of oceans and ocean productivity in the climate system and our ability to forecast change through models. Secondary objectives of the MERIS mission will be directed to the measurement of atmospheric parameters associated with clouds, water vapour and aerosols in addition to land surface parameters, important in particular for the understanding of vegetation processes. MERIS measures the radiance reflected from the Earth's surface in the visible and near infra-red part of the spectrum. Data are transmitted in fifteen spectral bands of programmable width and location. The instrument features two spatial resolution and several observation and calibration modes selectable by ground command. This paper gives an overview ofthe instrument mission, its concept and data products.
