ALADIN best\u00e5r af en kraftig laser og et stort teleskop, der er forbundet med en meget f\u00f8lsom modtager. Laseren sender korte impulser af intens lys ud i atmosf\u00e6ren. Dette lys spredes af gasmolekyler, st\u00f8vpartikler og vanddr\u00e5ber.<\/p>\n<p>En del af det tilbagekastede lys opfanges af rumfart\u00f8jets teleskop og sendes til modtageren om bord. Ved at analysere signalet er det muligt at beregne hastigheden og retningen af den bev\u00e6gelige luft i forskellige h\u00f8jder i atmosf\u00e6ren.<\/p>\n<\/p>\n<p>Fremtiden er her: Lasere.

Data, der lagres om bord p\u00e5 Aeolus, vil blive sendt hvert 90. minut til en jordstation p\u00e5 Svalbard i Norge. Denne str\u00f8m af information vil ikke blot bidrage til at forbedre vejrudsigterne, men ogs\u00e5 til langvarig klimaforskning.<\/p>\n<nav class=\"related\" aria-label=\"Relateret\">\n<h2 class=\"related__heading\">Relateret<\/h2>\n<div class=\"grid related__grid\">\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"http:\/\/esamultimedia.esa.int\/docs\/build_your_own_aeolus_model.pdf\" target=\"_blank\" rel=\"noopener\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Aeolus-papirmodel<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<\/div>\n<\/nav>","protected":false},"excerpt":{"rendered":"<p>It is easy to measure wind speed and direction at one place on the ground, but what are the winds like at different heights over the entire Earth?
