Har du n\u00e5gonsin f\u00e5tt solbr\u00e4nna? Denna br\u00e4nnskada p\u00e5 huden orsakas av ultraviolett (UV) ljus fr\u00e5n solen. Allvarlig solbr\u00e4nna \u00e4r inte bara sm\u00e4rtsam, utan kan \u00e4ven leda till hudcancer.<\/p>\n<\/div>\n

Lyckligtvis absorberas n\u00e4stan all skadlig UV-str\u00e5lning av ett skikt av ozongas som ligger 20\u201350 km ovanf\u00f6r jorden. Ozon \u00e4r dock en form av syre som l\u00e4tt kan brytas ned av vissa kemikalier som framst\u00e4lls av m\u00e4nniskan.<\/p>\n

\u00c5r 1987 enades de ledande industril\u00e4nderna om att fasa ut dessa kemikalier. Trots detta har satellitm\u00e4tningar visat att uttunningen av ozonskiktet har fortsatt \u00f6ver Antarktis. Ozonh\u00e5let n\u00e5dde en rekordstorlek \u00e5r 2000, d\u00e5 det t\u00e4ckte n\u00e4stan 30 miljoner kvadratkilometer, ungef\u00e4r lika stort som den nordamerikanska kontinenten. \u00c5r 2006 f\u00f6rsvann en \u00e4nnu st\u00f6rre m\u00e4ngd ozon fr\u00e5n atmosf\u00e4ren, trots att h\u00e5let var n\u00e5got mindre.<\/p>\n

\u00c4ven mindre ozonh\u00e5l har uppst\u00e5tt \u00f6ver Arktis. Dessa h\u00e5l g\u00f6r att mer UV-str\u00e5lning n\u00e5r t\u00e4tbefolkade omr\u00e5den i Europa.<\/p>\n

\"Ozone
Prognos f\u00f6r ozonh\u00e5let fr\u00e5n idag till den 9 september<\/figcaption><\/figure>\n

ESA:s satelliter, s\u00e5som MetOp och Envisat, spelar en avg\u00f6rande roll i forskningen om ozonh\u00e5let. De g\u00f6r det m\u00f6jligt f\u00f6r forskarna att \u00f6vervaka h\u00e5lets storlek och f\u00e5 mer kunskap om vad som f\u00e5r det att v\u00e4xa eller krympa.<\/p>\n

Europas f\u00f6rsta v\u00e4dersatellit i pol\u00e4r bana, MetOp-A, \u00e4r utrustad med ett avancerat instrument f\u00f6r ozon\u00f6vervakning. Envisat \u00e4r utrustad med tre instrument som kan unders\u00f6ka ozonet och de f\u00f6roreningar som bryter ned det i den \u00f6vre atmosf\u00e4ren.<\/p>","protected":false},"excerpt":{"rendered":"
