S\u00e4\u00e4 voi yht\u00e4kki\u00e4 huonontua, joten on eritt\u00e4in t\u00e4rke\u00e4\u00e4, ett\u00e4 s\u00e4\u00e4ennustajat saavat jatkuvasti ajantasaista tietoa avaruudesta.<\/p>\n<\/div>\n

Euroopan Meteosat-9-satelliitti l\u00e4hett\u00e4\u00e4 15 minuutin v\u00e4lein, y\u00f6ll\u00e4 tai p\u00e4iv\u00e4ll\u00e4, s\u00e4\u00e4kuvia l\u00e4hes kolmanneksesta maailmasta. Se kiert\u00e4\u00e4 36 000 km:n korkeudella L\u00e4nsi-Afrikan yl\u00e4puolella ja tarkkailee jatkuvasti samaa aluetta. Varasatelliitti on aina valmiina l\u00e4hell\u00e4 ottamaan teht\u00e4v\u00e4t hoitaakseen, jos ongelmia ilmenee.<\/p>\n

Visuaaliset, infrapuna- (l\u00e4mp\u00f6), vesih\u00f6yry- ja muut keskeiset tiedot l\u00e4hetet\u00e4\u00e4n Meteosat-satelliittien operaattorille, Eumetsatille. Raakadata k\u00e4sitell\u00e4\u00e4n Darmstadtissa, Saksassa, ja l\u00e4hetet\u00e4\u00e4n sen j\u00e4lkeen k\u00e4ytt\u00e4jille.<\/p>\n

Lokakuusta 2006 l\u00e4htien s\u00e4\u00e4tietoja on l\u00e4hetetty my\u00f6s Euroopan MetOp-A-satelliitista. T\u00e4m\u00e4n polaarikiertoradalla liikkuvan satelliitin tiedot v\u00e4litet\u00e4\u00e4n Norjan Spitsbergenin saarella sijaitsevan maa-aseman kautta. My\u00f6s kuvia ja tietoja ilmakeh\u00e4st\u00e4 ja merist\u00e4 l\u00e4hetet\u00e4\u00e4n jatkuvasti maahan paikallisten k\u00e4ytt\u00e4jien k\u00e4ytt\u00f6\u00f6n.<\/p>\n

Euroopan satelliitit ovat osa maailmanlaajuista s\u00e4\u00e4valvontaa. Monet eri maat jakavat satelliiteistaan saatua tietoa kesken\u00e4\u00e4n.<\/p>\n

Meteosat-satelliitit ovat auttaneet Euroopan yhteisty\u00f6kumppaneita my\u00f6s muilla tavoin. Kun er\u00e4s amerikkalainen satelliitti lakkasi toimimasta vuonna 1991, Meteosat-3 ylitti Atlantin ja otti sen teht\u00e4v\u00e4t hoitaakseen.<\/p>\n

Vuonna 1998 Meteosat-5 siirrettiin Intian valtameren yl\u00e4puolelle. Osana kansainv\u00e4list\u00e4 kokeilua se auttoi seuraamaan t\u00e4t\u00e4 aluetta, joka on tunnettu monsuuneistaan.<\/p>","protected":false},"excerpt":{"rendered":"
