\u00c0 quand remonte la derni\u00e8re fois o\u00f9 vous avez consult\u00e9 les pr\u00e9visions m\u00e9t\u00e9o ? C'est une habitude que beaucoup d'entre nous ont au quotidien, mais vous \u00eates-vous d\u00e9j\u00e0 demand\u00e9 comment on pr\u00e9voyait le temps ? La plupart de nos meilleures informations proviennent de satellites en orbite autour de la Terre, qui prennent des photos et effectuent des mesures qui vous aident \u00e0 savoir s'il faut emporter de la cr\u00e8me solaire ou un parapluie !<\/p>\n

Depuis 45 ans, des satellites appel\u00e9s \u00ab Meteosats \u00bb tournent autour de notre plan\u00e8te, surveillant la m\u00e9t\u00e9o en observant et en collectant des donn\u00e9es sur toute la partie de la Terre qui leur est visible. Il est d\u00e9sormais temps que de nouveaux Meteosats am\u00e9lior\u00e9s \u2013 appel\u00e9s \u00ab Meteosat de troisi\u00e8me g\u00e9n\u00e9ration \u00bb \u2013 s\u2019envolent dans l\u2019espace pour poursuivre cette importante mission ! Le premier d\u2019entre eux est en cours de pr\u00e9paration en vue d\u2019un lancement prochain, et cinq autres viendront progressivement le rejoindre. Ensemble, ils am\u00e9lioreront nos capacit\u00e9s de pr\u00e9vision m\u00e9t\u00e9orologique.<\/p>\n

Les nouveaux satellites Meteosat embarquent des instruments scientifiques absolument uniques. L'un de ces instruments est l'imageur combin\u00e9 flexible, qui est en mesure de prendre des photos de la Terre en haute r\u00e9solution avec un niveau de d\u00e9tails bien plus \u00e9lev\u00e9 que les satellites de g\u00e9n\u00e9ration pr\u00e9c\u00e9dente. L'imageur de d\u00e9tection des \u00e9clairs permettra quant \u00e0 lui d'anticiper la formation de nouveaux orages bien plus rapidement qu'auparavant. Un autre instrument contribuera \u00e0 collecter \u00e0 distance les donn\u00e9es transmises depuis des balises scientifiques sur Terre. Les satellites Meteosat de troisi\u00e8me g\u00e9n\u00e9ration peuvent aussi d\u00e9tecter les signaux \u00e9mis par les balises d'urgence activ\u00e9es par des personnes en d\u00e9tresse, permettant ainsi d'am\u00e9liorer les op\u00e9rations de secours pour sauver des vies.<\/p>\n

Les satellites Meteosat de troisi\u00e8me g\u00e9n\u00e9ration vont fonctionner pendant les 20 prochaines ann\u00e9es, de mani\u00e8re \u00e0 fournir des pr\u00e9visions m\u00e9t\u00e9orologiques de la plus haute pr\u00e9cision aux personnes du monde entier.\u00a0\u00a0<\/p>\n
