dc.description.abstract	The Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) is a phased-array radio detector located in Arctic Finland, where auroral electron precipitation is common. This unique deployment of a modern radio telescope in an unconventional location has resulted in a novel and powerful instrument capable of carrying out a large variety of remote-sensing, geoscience experiments. This work presents a selection of these and introduces the interferometric imaging riometry method.	en_US
dc.description.abstract	KAIRA eli Kilpisjärvi Atmospheric Imaging Receiver Array on Pohjois-Suomessa Kilpisjärvellä sijaitseva vaiheistettuihin antenniryhmiin perustuva radiovastaanotin. Alueella revontulet ja niihin liittyvät elektronipresipitaatio on yleistä. KAIRA on moderni radioteleskooppi epätyypillisessä paikassa, mikä on mahdollistanut useiden uusien kaukokartoitus- ja geofysikaalisten kokeiden kehittämisen. Tässä työssä esitellään näitä kokeita sekä niin kutsuttu interferometrisen kuvantavan riometrin menetelmä.	en_US
dc.description.abstract	Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) er en fasestyrt radiomottaker i arktisk Finland, hvor elektronnedbør ofte observeres i forbindelse med nordlys. Denne unike plasseringen av et radioteleskop, på et ukonvensjonelt sted, har resultert i et nytt og kraftig verktøy for fjernmåling, egnet for et stort spenn av eksperimenter innen geovitenskap. I denne avhandlingen presenteres et utvalg av disse eksperimentene og en metode for interferometrisk avbildende riometri introduseres.	en_US

dc.description.popularabstract	The Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) is a new scientific instrument located in Arctic Finland, where the Northern Lights are a common occurrence. This unique deployment of a modern radio telescope in an unconventional location has resulted in a novel and powerful instrument capable of carrying out a large variety of experiments for astronomy and atmospheric research. In particular a new method of making images of the Northern Lights has been developed. This technique uses radio waves, which means it can operate during cloudy weather or during summer when there is midnight sun.	en_US
