Skyer av kvelende smog; strender dekket av olje; elver som har blitt r\u00f8de av kjemikalier. Alt dette er \u00e5penbare eksempler p\u00e5 forurensning.<\/p>\n<\/div>\n

Imidlertid er ikke alle former for forurensning lett \u00e5 se. For eksempel kan usynlige gassskyer sveve over byene v\u00e5re. De kan for\u00e5rsake astma og luftveisplager. De kan ogs\u00e5 drepe tr\u00e6r.<\/p>\n

Et annet problem er \u00e5 finne ut hvor stort det ber\u00f8rte omr\u00e5det er. Vind kan bl\u00e5se forurensende stoffer over tusenvis av kilometer, fra den ene siden av et hav til den andre. Kjemikalier som str\u00f8mmer ned store elver kan forurense mange land p\u00e5 veien mot havet.<\/p>\n

S\u00e5 er det problemet med \u00e5 finne ut hvem som har skylden.<\/p>\n

Satellitter er viktige verkt\u00f8y i denne uendelige kampen for \u00e5 holde planeten ren. Rombaserte instrumenter kan oppdage skadelige gasser og kjemisk avfall som slippes ut fra industrien, kraftverk og trafikken.<\/p>\n

Satellitter kan lokalisere forurensningskildene, f\u00f8lge forurensningen mens den beveger seg gjennom luften og se hvor den havner. De kan ogs\u00e5 unders\u00f8ke havets farge og oppdage oljeutslipp til sj\u00f8s, b\u00e5de om dagen og om natten.<\/p>\n

Fra hundrevis av kilometer over jorden bidrar disse \u201cspionene i himmelen\u201d til \u00e5 identifisere de st\u00f8rste utslippskildene og mottakerne av forurensning over hele verden.<\/p>","protected":false},"excerpt":{"rendered":"
