L'Europe a son propre r\u00e9seau de satellites m\u00e9t\u00e9o, app\u00e9l\u00e9 Meteosat. Le premier Meteosat a \u00e9t\u00e9 lanc\u00e9 par l'ESA en orbite g\u00e9ostationnaire, \u00e0 36 000 km au-dessus du golfe de Guin\u00e9e le 23 novembre 1977.<\/p>\n<\/div>\n

Depuis, huit autres satellites Meteosat ont \u00e9t\u00e9 lanc\u00e9s. Le dernier en date (Meteosat-9) est devenu compl\u00e8tement op\u00e9rationnel le 29 janvier 2004. Deux autres satellites sont pr\u00e9vus dans les deux ann\u00e9es \u00e0 venir, suivis par une troisi\u00e8me g\u00e9n\u00e9ration de satellites.<\/p>\n

Les derniers satellites Meteosat (dits de \u2018 deuxi\u00e8me g\u00e9n\u00e9ration \u2019) pr\u00e9sentent de nombreuses am\u00e9liorations techniques par rapport aux mod\u00e8les pr\u00e9c\u00e9dents. L'un de leurs avantages est qu'ils peuvent transmettre des images plus nettes et \u00e0 une fr\u00e9quence plus \u00e9lev\u00e9e.<\/p>\n

Meteosat-9 poss\u00e8de un instrument capable d\u2019\u00e9tudier les nuages, les sols, les oc\u00e9ans, la neige et la glace, le jour comme la nuit. Un autre instrument est d\u00e9di\u00e9 aux \u00e9tudes climatiques. Les donn\u00e9es collect\u00e9es aident les pr\u00e9visionnistes m\u00e9t\u00e9o \u00e0 d\u00e9tecter et pr\u00e9dire les \u00e9v\u00e9nements dangereux. Il s'agit de brouillards denses, d'orages et de l'apparition soudaine de temp\u00eates intenses avec vents violents et pluie battante. Les pr\u00e9visions \u00e0 long terme sont aussi am\u00e9lior\u00e9es.<\/p>\n

Effectuant un tour de la Terre toutes les 101 minutes, le satellite MetOp \u00e9tudie presque toute la plan\u00e8te deux fois par jour. Gr\u00e2ce \u00e0 ses onze instruments, il transmet des donn\u00e9es tr\u00e8s d\u00e9taill\u00e9es et tr\u00e8s pr\u00e9cises sur les nuages, la temp\u00e9rature, l\u2019humidit\u00e9, l\u2019ozone, les vents \u00e0 la surface des oc\u00e9ans et d\u2019autres informations m\u00e9t\u00e9orologiques utiles.<\/p>","protected":false},"excerpt":{"rendered":"
