K\u00f5rgel Antarktika j\u00e4ise mandri kohal hoiab ESA kosmosesond Envisat valvet \u2013 ja see, mida selle seadmed n\u00e4evad, on \u00fcsna murettekitav.<\/p>\n<\/div>\n

K\u00fclmakraadid ja inimtekkelised kemikaalid p\u00f5hjustavad koos \u2018augu\u2019 osoonikihis. Ja tundub, et t\u00e4navune osooniauk on \u00fcks suurimaid, mida kunagi on registreeritud.<\/p>\n

2005. aasta augusti keskpaigaks oli see juba paisunud 10 miljoni ruutkilomeetri suuruseks \u2013 umbes sama suur kui Euroopa. Ja eeldati, et septembri jooksul laieneb see veelgi.<\/p>\n

Osooniauk avastati esmakordselt 1980. aastate keskel ning ESA satelliidid on seda alates 1995. aastast pidevalt uurinud. Nende andmetest selgub, et ainult 1996. ja 2000. aasta osooniaugud olid sel aastaajal suuremad.<\/p>\n

Osoon on hapniku \u00fcks vorm. V\u00e4ikeseid koguseid osooni leidub stratosf\u00e4\u00e4ris, 20\u201350 km k\u00f5rgusel Maa kohal.<\/p>\n

Meie \u00f5nneks kaitseb osoonikiht meid p\u00e4ikese ultraviolettkiirguse eest, mis v\u00f5ib p\u00f5hjustada nahav\u00e4hki. Siiski h\u00e4vitavad osooni keemilised reaktsioonid, milles osaleb inimtegevuse tulemusel tekkinud kloori k\u00f5rgetes pilvedes.<\/p>\n

Polaarkevade saabudes p\u00f5hjustab tagasitulev p\u00e4ikesevalgus koos kloori keemiliste reaktsioonidega osoonimolekulide lagunemise hapnikuks. \u00dcksainus kloori molekul v\u00f5ib lagundada tuhandeid osoonimolekule.<\/p>\n

Envisati andmed on h\u00e4davajalikud selle kaitsva kihi hooajaliste muutuste j\u00e4lgimiseks. Satelliidiandmed edastatakse peaaegu reaalajas toimivale osooni seire- ja prognoositeenistusele, milles osaleb \u00fcle 30 partneri 11 riigist.<\/p>","protected":false},"excerpt":{"rendered":"
