Luften er fyldt med sm\u00e5, sv\u00e6vende st\u00f8vpartikler og dr\u00e5ber \u2013 ogs\u00e5 kaldet \u201caerosoler\u201d. Mange aerosoler dannes naturligt. Heriblandt er sand fra \u00f8rkenst\u00f8vstorme, saltpartikler fra havet, iskrystaller samt aske fra brande og vulkanudbrud.<\/p>\n<\/div>\n

Menneskets aktiviteter medf\u00f8rer ogs\u00e5 en stigning i m\u00e6ngden af aerosoler i atmosf\u00e6ren. Aerosoler best\u00e5ende af sort sod og svovldioxid stiger op fra \u201cforurenende\u201d kraftv\u00e6rker og fabriksskorstene. Andre aerosoler udledes fra biludst\u00f8dninger og flymotorer.<\/p>\n

Aerosoler er s\u00e5 sm\u00e5, at de kan spredes over hele verden. De kan for\u00e5rsage astma og f\u00f8re til sur regn, der dr\u00e6ber fisk og tr\u00e6er. De spiller ogs\u00e5 en rolle i klimaforandringerne, fordi de absorberer og spreder sollys. Data, der sendes tilbage fra satellitter, hj\u00e6lper forskerne med at unders\u00f8ge aerosolernes spredning og den indvirkning, de har p\u00e5 planeten.<\/p>\n

Fire instrumenter ombord p\u00e5 ESA\u2019s Envisat bruges til at kortl\u00e6gge koncentrationerne af st\u00f8vpartikler og skydr\u00e5ber, fra jordoverfladen og op til en h\u00f8jde p\u00e5 100 km. De kan registrere de skyer af aerosoler og forurenende stoffer, der l\u00e6gger sig som et t\u00e6ppe over store industribyer eller br\u00e6ndende skove. Og de kan udpege de udst\u00f8dningsspor, som passagerfly efterlader i den \u00f8vre atmosf\u00e6re.<\/p>","protected":false},"excerpt":{"rendered":"
