Moln av kv\u00e4vande smog; oljeindr\u00e4nkta str\u00e4nder; floder som f\u00e4rgats r\u00f6da av kemikalier. Allt detta \u00e4r tydliga exempel p\u00e5 f\u00f6roreningar.<\/p>\n<\/div>\n

Det \u00e4r dock inte alla typer av f\u00f6roreningar som syns tydligt. Till exempel kan osynliga gasmoln sv\u00e4va \u00f6ver v\u00e5ra st\u00e4der och t\u00e4torter. De kan orsaka astma och andningsbesv\u00e4r. De kan ocks\u00e5 d\u00f6da tr\u00e4d.<\/p>\n

Ett annat problem \u00e4r att fastst\u00e4lla storleken p\u00e5 det drabbade omr\u00e5det. Vindar kan f\u00f6ra med sig f\u00f6roreningar \u00f6ver tusentals kilometer, fr\u00e5n ena sidan av ett hav till den andra. Kemikalier som rinner ut i stora floder kan f\u00f6rorena m\u00e5nga l\u00e4nder p\u00e5 sin v\u00e4g mot havet.<\/p>\n

Sedan \u00e4r det fr\u00e5gan om att ta reda p\u00e5 vem som b\u00e4r skulden.<\/p>\n

Satelliter \u00e4r viktiga verktyg i denna o\u00e4ndliga kamp f\u00f6r att h\u00e5lla planeten ren. Rymdbaserade instrument kan uppt\u00e4cka skadliga gaser och kemiskt avfall som sl\u00e4pps ut av industrin, kraftverk och trafiken.<\/p>\n

Satelliter kan lokalisera f\u00f6roreningsk\u00e4llor, f\u00f6lja hur f\u00f6roreningarna sprids i luften och se var de hamnar. De kan ocks\u00e5 unders\u00f6ka havets f\u00e4rg och uppt\u00e4cka oljeutsl\u00e4pp till havs, b\u00e5de dag och natt.<\/p>\n

Fr\u00e5n hundratals kilometer ovanf\u00f6r jorden bidrar dessa \u201cspioner i skyn\u201d till att identifiera de st\u00f6rsta export\u00f6rerna och import\u00f6rerna av f\u00f6roreningar v\u00e4rlden \u00f6ver.<\/p>","protected":false},"excerpt":{"rendered":"
