Var den pr\u00e6cis? Det er meget sv\u00e6rt at forudsige vejret, men pr\u00e6cise vejrudsigter er vigtige. De er til stor hj\u00e6lp inden for landbrug, fiskeri, byggeri, transport og ikke mindst n\u00e5r man skal planl\u00e6gge sin dag! Vejrudsigterne bliver mere og mere p\u00e5lidelige, men der er et presserende behov for bedre oplysninger om vinden. For at afhj\u00e6lpe dette forbereder ESA sig p\u00e5 at opsende en ny satellit ved navn Aeolus.<\/p>\n<\/div>\n<p><i>S\u00e5dan vil Aeolus se ud, n\u00e5r den er i kredsl\u00f8b om Jorden. Ophavsret: ESA\/ATG Medialab.<\/i><\/p>\n<p>De fleste satellitter er udstyret med mange forskellige instrumenter, men Aeolus har kun \u00e9t meget vigtigt instrument. Det hedder Aladin og bruger to kraftige lasere, et stort teleskop og meget f\u00f8lsomme modtagere. Laserstr\u00e5lerne sender ultraviolet lys mod Jorden, som reflekteres af luftmolekyler, st\u00f8v, is og vanddr\u00e5ber i atmosf\u00e6ren. Det resterende lys, der reflekteres tilbage mod satellitten, opfanges af Aladins teleskop og m\u00e5les derefter. Ved hj\u00e6lp af denne teknik kan Aeolus unders\u00f8ge de nederste 30 km af Jordens atmosf\u00e6re og m\u00e5le vindene, mens de hvirvler rundt om vores planet.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"4625\" data-credit=\"Copyright contains modified Copernicus Sentinel data (2017), processed by ESA, CC BY-SA 3.0 IGO\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/08\/Hurricane_Ophelia\" data-licence=\"CC BY-SA 3.0 IGO or ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2018\/08\/hurricane_ophelia\/17909308-2-eng-GB\/Hurricane_Ophelia.jpg\" alt=\"Hurricane Ophelia\"><figcaption>Orkanen Ophelia<\/figcaption><\/figure>\n<p>Aeolus-vindmissionen vil hj\u00e6lpe os med at udarbejde n\u00f8jagtige og p\u00e5lidelige kort over vindforholdene rundt om Jorden, s\u00e5 vi kan se, hvordan de \u00e6ndrer sig, og dermed lave brugbare vejrudsigter.

Aeolus-missionen forventes at vare tre \u00e5r, og hvis den bliver s\u00e5 vellykket, som man h\u00e5ber, vil den m\u00e5ske bane vejen for flere satellitter til overv\u00e5gning af vinden.<\/p>\n<p><b>Sjovt faktum:<\/b> Aeolus er opkaldt efter \u201cvindernes herre\u201d fra den antikke gr\u00e6ske mytologi.<\/p>","protected":false},"excerpt":{"rendered":"<p>When was the last time you checked the weather forecast?
