Luften \u00e4r full av sm\u00e5, sv\u00e4vande dammpartiklar och droppar \u2013 s\u00e5 kallade \u201caerosoler\u201d. M\u00e5nga aerosoler bildas naturligt. Bland dessa finns sand fr\u00e5n sandstormar i \u00f6knen, saltpartiklar fr\u00e5n havet, iskristaller samt aska fr\u00e5n br\u00e4nder och vulkanutbrott.<\/p>\n<\/div>\n

M\u00e4nsklig verksamhet bidrar ocks\u00e5 till att \u00f6ka m\u00e4ngden aerosoler i atmosf\u00e4ren. Aerosoler i form av svart sot och svaveldioxid sl\u00e4pps ut fr\u00e5n \u201csmutsiga\u201d kraftverk och fabriksskorstenar. Andra aerosoler sl\u00e4pps ut fr\u00e5n bilavgaser och flygplansmotorer.<\/p>\n

Aerosoler \u00e4r s\u00e5 sm\u00e5 att de kan spridas \u00f6ver hela v\u00e4rlden. De kan orsaka astma och leda till surt regn som d\u00f6dar fiskar och tr\u00e4d. De bidrar ocks\u00e5 till klimatf\u00f6r\u00e4ndringarna eftersom de absorberar och sprider solljus. Data som skickas tillbaka fr\u00e5n satelliter hj\u00e4lper forskarna att studera aerosolernas spridning och deras inverkan p\u00e5 jorden.<\/p>\n

Fyra instrument ombord p\u00e5 ESA:s satellit Envisat anv\u00e4nds f\u00f6r att kartl\u00e4gga koncentrationerna av dammpartiklar och molndroppar, fr\u00e5n markniv\u00e5 upp till en h\u00f6jd av 100 km. De kan uppt\u00e4cka moln av aerosoler och f\u00f6roreningar som t\u00e4cker stora industrist\u00e4der eller brinnande skogar. Dessutom kan de urskilja avgassp\u00e5r som flygplan l\u00e4mnar efter sig i den \u00f6vre atmosf\u00e4ren.<\/p>","protected":false},"excerpt":{"rendered":"
