V diplomski nalogi poizkušamo prikazati širjenje vulkanskega pepela ob izbruhu vulkana Eyjafjallajökull na Islandiji leta 2010, prek Evrope do Slovenije. Predstavljena je grožnja, ki jo ob izbruhu vulkanskega pepela predstavlja vulkanski pepel letalskemu prometu in posledično tudi letalskim družbam, ki so takrat utrpele ogromno denarno škodo. V diplomski nalogi smo analizirali predvsem širjenje vulkanskega pepela prve tri dni, ko je bil izbruh najbolj intenziven in se je razširil skoraj po celotni Evropi. Za to predstavitev smo uporabili satelitske posnetke senzorja SEVIRI, ki je nameščen na satelitu MSG-2. Predstavljene so tudi metode in algoritmi zaznavanja vulkanskega pepela v atmosferi in sateliti s senzorji, ki so zmožni zaznavanja vulkanskega pepela na podlagi infrardečega valovanja. The aim of this thesis is to demonstrate the spread of volcanic ash in the eruption of Eyjafjallajökull volcano in Iceland in 2010 which disseminated all the way to Slovenia. We describe the threat that the volcanic ash presents for air traffic and, consequently, airlines, who suffered a huge financial loss. In this thesis, we mainly analyse the spread of volcanic ash in the first three days, when the outbreak was most intense and has spread almost all over Europe. For this presentation we used satellite images of SEVIRI sensor, which is mounted on the MSG-2 satellite. We also demonstrate methods and algorithms of detection of the volcanic ash in the atmosphere and satellites with sensors capable of detecting the volcanic ash on the basis of infrared waves.
