Har du nogensinde haft solskoldning? Denne forbr\u00e6nding af huden skyldes ultraviolet (UV) lys fra solen. Alvorlig solskoldning er ikke kun smertefuld, men kan ogs\u00e5 medf\u00f8re hudkr\u00e6ft.<\/p>\n<\/div>\n

Heldigvis absorberes n\u00e6sten al den skadelige UV-str\u00e5ling af et lag af ozongas, der befinder sig 20\u201350 km over Jorden. Ozon er imidlertid en form for ilt, der let kan nedbrydes af visse menneskeskabte kemikalier.<\/p>\n

I 1987 blev de f\u00f8rende industrilande enige om at udfase disse kemikalier. Alligevel har satellitbilleder vist, at udtyndingen af ozonlaget er fortsat over Antarktis. Ozonhullet n\u00e5ede en rekordst\u00f8rrelse i 2000, hvor det d\u00e6kkede n\u00e6sten 30 millioner kvadratkilometer, hvilket svarer til omtrent st\u00f8rrelsen af det nordamerikanske kontinent. I 2006 forsvandt der en endnu st\u00f8rre m\u00e6ngde ozon fra atmosf\u00e6ren, selvom hullet var lidt mindre.<\/p>\n

Der er ogs\u00e5 opst\u00e5et mindre ozonhuller over Arktis. Disse huller g\u00f8r, at der tr\u00e6nger mere UV-lys ind i t\u00e6tbefolkede omr\u00e5der i Europa.<\/p>\n

Prognose for ozonhullet fra i dag til den 9. september<\/figcaption><\/figure>\n

ESA-satellitter som MetOp og Envisat spiller en central rolle i unders\u00f8gelserne af ozonhullet. De giver forskerne mulighed for at overv\u00e5ge hullets st\u00f8rrelse og f\u00e5 mere at vide om, hvad der f\u00e5r det til at vokse eller krympe.<\/p>\n

Europas f\u00f8rste vejrsatellit i pol\u00e6r bane, MetOp-A, er udstyret med et avanceret instrument til overv\u00e5gning af ozon. Envisat er udstyret med tre instrumenter, der kan unders\u00f8ge ozon og de forurenende stoffer, der nedbryder det i den \u00f8vre atmosf\u00e6re.<\/p>","protected":false},"excerpt":{"rendered":"
