Euroopalla on omat s\u00e4\u00e4satelliittinsa, joita kutsutaan nimell\u00e4 Meteosat. ESA laukaisi ensimm\u00e4isen Meteosat-satelliitin geostationaariselle kiertoradalle, 36 000 km:n korkeuteen Guineanlahden yl\u00e4puolelle, 23. marraskuuta 1977.<\/p>\n<\/div>\n

Siit\u00e4 l\u00e4htien on laukaistu viel\u00e4 kahdeksan Meteosat-satelliittia. N\u00e4ist\u00e4 uusin (Meteosat-9) aloitti t\u00e4ysimittaisen toimintansa 29. tammikuuta 2004. Seuraavien vuosien aikana on suunniteltu viel\u00e4 kaksi satelliittia, joita seuraa kolmannen sukupolven satelliitit.<\/p>\n

Uusimmissa Meteosat-satelliiteissa (ns. \u2018toisen sukupolven\u2019 satelliiteissa) on monia rakenteellisia parannuksia aiempiin malleihin verrattuna. Yksi etu on, ett\u00e4 ne pystyv\u00e4t l\u00e4hett\u00e4m\u00e4\u00e4n ter\u00e4v\u00e4mpi\u00e4 kuvia entist\u00e4 useammin.<\/p>\n

Meteosat-9:ss\u00e4 on yksi laite, jolla voidaan tutkia pilvi\u00e4, maata, merta, lunta ja j\u00e4\u00e4t\u00e4 sek\u00e4 p\u00e4iv\u00e4ll\u00e4 ett\u00e4 y\u00f6ll\u00e4. Toinen laite on tarkoitettu ilmastotutkimuksiin. Ker\u00e4tyt tiedot auttavat s\u00e4\u00e4ennustajia tunnistamaan ja ennustamaan vaarallista s\u00e4\u00e4t\u00e4. T\u00e4h\u00e4n kuuluvat tihe\u00e4 sumu, ukkosmyrskyt sek\u00e4 voimakkaiden myrskyjen \u00e4killinen voimistuminen, johon liittyy myrskytuuli ja kaatosade. My\u00f6s pitk\u00e4n aikav\u00e4lin ennusteet tarkentuvat.<\/p>\n

Lokakuuhun 2006 asti yht\u00e4\u00e4n eurooppalaista s\u00e4\u00e4satelliittia ei ollut sijoitettu polaarikiertoradalle. Tilanne muuttui, kun MetOp-A-niminen satelliitti laukaistiin. Sarjan toinen satelliitti, MetOp-B, laukaistiin 17. syyskuuta 2012, ja se toimii yhdess\u00e4 MetOp-A:n kanssa, mik\u00e4 lis\u00e4\u00e4 tietom\u00e4\u00e4r\u00e4\u00e4 entisest\u00e4\u00e4n. Kolmas ja viimeinen satelliitti, MetOp-C, laukaistaan vuonna 2016.<\/p>","protected":false},"excerpt":{"rendered":"
