The Medium Resolution Imaging Spectrometer MERIS forms part of the core instrument payload of ESA's environmental research satellite ENVISAT-1. MERIS is funded by ESA. The demands of the European scientific community for a global environmental monitoring system, whose technical characteristics enable the extraction of quantitative information from ocean colour data, as well as for documentation of the state and evolution of the atmosphere and land surfaces, led to the conception of MERIS. The oceanographic mission is radiometrically the most demanding in terms of low radiance levels and their associated high signal-to-noise ratios. The instrument will be capable of detecting the low levels of radiation emerging from the ocean(linked to the water constituents by the processes of absorption and scattering), in addition to acquiring information about the atmospheric medium through which the observation is made as well as terrestrial environments. The characteristics of MERIS will also be of great value for the retrieval of information on land surfaces, in particular that of global biomass.  5, record 3, English, - medium%20resolution%20imaging%20spectrometer%20MERIS

The other major new mode is referred to as Ultra-Fine, providing swath imaging with resolution of about 3 m in each dimension.

Les systèmes embarqués à bord des satellites comportent de multiples instruments dont les fonctions sont variées. Toutefois, pour une mission donnée, les instruments de la charge utile ont des fonctions bien particulières. Il s'agit le plus souvent de capteurs qui ont pour vocation d'effectuer des mesures du rayonnement émis ou rémis par la Terre, l'atmosphère ou divers objets de l'Univers, ou bien de dispositifs de réception et de réémission de signaux, quand il s'agit de missions de télécommunications, par exemple. Deux grandes familles de capteurs sont identifiables : les capteurs non-imageurs et les capteurs-imageurs, ces derniers restituant sous forme d'images les observations effectuées dans un champ donné. Les principales caractéristiques d'un capteur-imageur sont : - le champ d'observation total (de quelques dizaines à quelques millions de km) [;] - la résolution spatiale (qui exprime son aptitude à distinguer les détails dans le champ total d'observation) [;] - les bandes spectrales (domaines de sensibilité spectrale des détecteurs et de leurs accessoires (filtres...] [;] - la résolution radiométrique (qui caractérise l'aptitude des détecteurs à distinguer des signaux porteurs de plus ou moins d'énergie).  4, record 11, French, - capteur%20imageur

Record number: 13, Textual support number: 1 CONT

The incidence angle is commonly used to describe the angular relationship between the radar beam and the ground, surface layer or a target. A change of the radar illumination angle often affects the radar backscattering behaviour of a surface or target. The incidence angle changes across the radar image swath; it increases from near range to far range. In the case of satellite radar imagery, the change of incidence angle for flat terrain across the imaging swath tends to be rather small, usually on the order of several degrees. In the case of an inclined surface(slope), the local incidence angle is defined as the angle between the incident radar beam and a line that is normal to that surface. The local incidence angle determining, in part, the brightness, or image tone, for each picture element(pixel) and slope facet, is a key element in the prominent rendition of terrain features in radar imagery.  3, record 13, English, - incidence%20angle

The Landsat program, first known as the Earth Resources Technology Satellite(ERTS) Program, is a development of the National Aeronautics and Space Administration(NASA) in association with NOAA, USGS, and the Space Imaging. The activities of these combined groups led to the concept of dedicated Earth-orbiting satellites, the defining of spectral and spatial requirements for their instruments, and the fostering of research to determine the best means of extracting and using information from the data.  4, record 20, English, - LANDSAT

The satellite performances remain very good and similar to those of ERS-1, making possible the unique nine-month ERS-1/ERS-2 Tandem Operation phase, which started in September. The main objective is to perform interferometric imaging of the land surface on a global basis leading to, among other important goals, a quasi-global digital terrain map.  2, record 21, English, - tandem%20operation%20phase

The Clouds and the Earth's Radiant Energy System(CERES) experiment is one of the highest priority scientific satellite instruments developed for EOS. CERES products include both solar-reflected and Earth-emitted radiation from the top of the atmosphere to the Earth's surface. Cloud properties are determined using simultaneous measurements by other EOS instruments such as the Moderate Resolution Imaging Spectroradiometer(MODIS). Analyses of the CERES data, which build upon the foundation laid by previous missions such as the Earth Radiation Budget Experiment(ERBE), will lead to a better understanding of the role of clouds and the energy cycle in global climate change.  3, record 22, English, - Clouds%20and%20Earth%26rsquo%3Bs%20Radiant%20Energy%20System

ASTER(Advanced Spaceborne Thermal Emission and Reflection Radiometer) is an imaging instrument that is flying on Terra, a satellite launched in December 1999 as part of NASA's Earth Observing System(EOS). ASTER is a cooperative effort between NASA and Japan's Ministry of Economy, Trade and Industry(METI) and the Earth Remote Sensing Data Analysis Center(ERSDAC). ASTER will be used to obtain detailed maps of land surface temperature, emissivity, reflectance and elevation. The EOS platforms are part of NASA's Earth Science Enterprise, whose goal is to obtain a better understanding of the interactions between the biosphere, hydrosphere, lithosphere and atmosphere.  2, record 23, English, - advanced%20spaceborne%20thermal%20emission%20and%20reflection%20radiometer

"The resolution of a satellite image of the earth depends on the height of the satellite's orbit and the quality of the recording equipment, "says Steve Drury, an expert on satellite imaging. "The lower the orbit and the better the equipment, the clearer and more detailed the image will be. But every image is affected by atmospheric shimmer, caused by the movement of hot and cold currents of air in the atmosphere. Because different air currents have different refractive indices, the light travelling through them is bent slightly, so the image that the satellite receives is out of focus and blurred. "The most obvious effect of atmospheric shimmer(or turbulence) that we can see from earth is the twinkling of stars. Light from stars is blurred as it passes through the earth's atmosphere.  4, record 24, English, - atmospheric%20shimmer

Toutefois, le scintillement, ainsi que d'autres effets atmosphériques, sont des problèmes sérieux pour les astronomes lorsqu'ils travaillent. Les images stellaires, lorsqu'elles sont vues à travers un télescope, semblent danser et être affectées par toutes sortes de distorsions, créant ainsi des images floues. Afin d'obtenir des images plus nettes, et par le fait même extraire plus d'information de leurs observations, des astronomes et des ingénieurs ont joint leurs efforts dans le but de développer des appareils innovateurs pouvant corriger les effets atmosphériques en temps réel.  1, record 24, French, - effet%20atmosph%C3%A9rique
