Kas olete kunagi p\u00f5lenud p\u00e4ikesest? Seda naha p\u00f5letust p\u00f5hjustab p\u00e4ikesest p\u00e4rinev ultraviolettkiirgus (UV). T\u00f5sine p\u00f5letus ei ole mitte ainult valus, vaid v\u00f5ib p\u00f5hjustada ka nahav\u00e4hki.<\/p>\n<\/div>\n

\u00d5nneks neelab peaaegu kogu kahjuliku UV-kiirguse \u00e4ra osoonikihi, mis asub 20\u201350 km k\u00f5rgusel Maa kohal. Osoon on aga hapniku vorm, mida teatud inimtekkelised kemikaalid v\u00f5ivad kergesti h\u00e4vitada.<\/p>\n

1987. aastal leppisid juhtivad t\u00f6\u00f6stusriigid kokku, et need kemikaalid j\u00e4rk-j\u00e4rgult kasutuselt k\u00f5rvaldatakse. Sellest hoolimata on satelliidid n\u00e4idanud, et osoonikihi h\u00f5renemine Antarktika kohal on j\u00e4tkunud. Osooniauk saavutas rekordilise suuruse 2000. aastal, mil see h\u00f5lmas ligi 30 miljonit ruutkilomeetrit, mis on umbes P\u00f5hja-Ameerika mandri suurusega. 2006. aastal kadus atmosf\u00e4\u00e4rist veelgi suurem kogus osooni, kuigi auk oli veidi v\u00e4iksem.<\/p>\n

Arktika kohal on tekkinud ka v\u00e4iksemad osooniaugud. Need augud v\u00f5imaldavad rohkem ultraviolettkiirgust j\u00f5uda Euroopa tihedalt asustatud piirkondadesse.<\/p>\n

Osooniaugu prognoos alates t\u00e4nasest kuni 9. septembrini<\/figcaption><\/figure>\n

ESA satelliidid, nagu MetOp ja Envisat, m\u00e4ngivad osooniaugu uuringutes olulist rolli. Need v\u00f5imaldavad teadlastel j\u00e4lgida augu suurust ja saada rohkem teavet selle kohta, mis p\u00f5hjustab augu suurenemist v\u00f5i kahanemist.<\/p>\n

Euroopa esimene polaarorbiidil tiirlev ilmasatelliit MetOp-A on varustatud kaasaegse osooni seireseadmega. Envisatil on kolm seadet, millega saab uurida osooni ja seda \u00fclemises atmosf\u00e4\u00e4ris kahjustavaid saasteaineid.<\/p>","protected":false},"excerpt":{"rendered":"
