Juha Vierinen
Job description
Jeg er en eksperimentalist som jobber med en rekke temaer innen romfysikk. Jeg spesialiserer meg på utvikling av nye teknikker for radar- og radiofjernmåling, og anvender dem på vitenskapelige studier innen romplasmafysikk, atmosfærefysikk, romsøppel og planetvitenskap. Mye av dette arbeidet utføres med høyeffektive radarer med stor åpning, ionosfæriske oppvarmingsanlegg, ionosondenettverk, meteorradarnettverk, radioteleskoper og globale navigasjonssatellittnettverk.
