The shoeboxsized spectrophotometer-called MAESTRO(Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation)-is the most advanced in a long line of MSC instruments that have flown on balloons, high-altitude research aircraft and space shuttle missions over the past 10 years. MAESTRO and other spectrophotometers operate on the principle that different gases absorb different wavelengths of light, ranging from short, ultraviolet(UV) rays to long, near-infrared ones. Each gas, therefore, has its own "fingerprint" or distinct spectrum of absorption. This makes it possible to identify which gases are present from changes in the brightness of sunlight at different wavelengths between light coming directly from the Sun and light that has passed through the atmosphere on the way to the spectrophotometer. Ozone, for example, absorbs UV light and is, therefore, essential to preventing high levels of these rays from reaching the Earth's surface. As the Sun rises and sets, its rays slice through different layers of the atmosphere and out into space. MAESTRO will be equipped with more than 2000 separate detectors record the full spectrum of wavelengths emitted by direct sunlight and by sunlight travelling through these layers. These data will then be analyzed to provide precise measurements of gases and aerosol particles at different heights in the atmosphere. SCISAT-1 will orbit the Earth 15 times a day at a height of 650 kilometres, allowing MAESTRO to take measurements of 30 sunrises and sunsets every 24 hours. 3, record 5, English, - spectrophotometer%20MAESTRO

Le spectrophotomètre, qui est de la taille d'une boîte à chaussures, porte le nom de MAESTRO pour «Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation» (Mesure de l'extinction des aérosols par occultation dans la stratosphère et dans la troposphère); il est le plus perfectionné d'une longue série d'instruments du SMC qui ont été embarqués à bord de ballons, d'avions de recherche en haute altitude et de navettes spatiales en mission au cours des dix dernières années. Le fonctionnement de MAESTRO, ainsi que d'autres spectrophotomètres, repose sur le principe que différents gaz absorbent différentes longueurs d'onde lumineuse, depuis les rayons ultraviolets (UV) à ondes courtes jusqu'aux rayons du proche-infrarouge à plus grande longueur d'onde. Chaque gaz, par conséquent, a sa propre «empreinte», c'est-à-dire son propre spectre d'absorption. Grâce à cela, il est possible de déterminer quels gaz sont présents à partir des changements dans l'intensité de la lumière du soleil à différentes longueurs d'onde entre la lumière qui provient directement du soleil et la lumière qui a traversé l'atmosphère avant de se rendre au spectrophotomètre. L'ozone, par exemple, absorbe la lumière UV et est, par conséquent, essentiel à la prévention d'un rayonnement ultraviolet intense sur la surface terrestre. 2, record 5, French, - spectrophotom%C3%A8tre%20MAESTRO

Bien que d'une conception similaire à celle de ses prédécesseurs, MAESTRO est le premier dispositif pourvu de deux spectrophotomètres distincts qui fonctionnent simultanément pour être en mesure d'enregistrer toutes les longueurs d'ondes du spectre. Les instruments utilisés antérieurement devaient être munis de filtres différents selon qu'ils mesuraient les rayons UV ou la lumière visible du spectre; c'était là un procédé qui réduisait le temps d'observation précieux dont on disposait. Pour obtenir un profil vertical complet de l'atmosphère au lever et au coucher du Soleil, MAESTRO recueillera des données sur toutes les longueurs d'onde du spectre correspondant à une hauteur donnée, ceci en seulement un tiers de seconde. Cela permettra aux scientifiques de détecter dans le profil vertical des gaz des détails d'une très grande précision, par exemple à un kilomètre d'altitude. 2, record 5, French, - spectrophotom%C3%A8tre%20MAESTRO

The ozone layer is the principal shield preventing harmful short-wave ultraviolet radiation from reaching the surface of the earth. Suggestions that man's activities may be leading to a moderate reduction of the stratospheric ozone layer is of justifiable concern. Several threats such as exhaust emissions from high altitude aircraft and halomethanes diffusing up from the troposphere appear to have a sound theoretical support to serve as a basis of concern. 3, record 7, English, - halogenated%20methane
