BAKTRAK: Backtracking drifting objects using an iterative algorithm with a forward trajectory model
Breivik, Øyvind; Bekkvik, Tor Christian; Wettre, Cecilie Drabløs; Ommundsen, Atle (2012)The task of determining the origin of a drifting object after it has been located is highly complex due to the uncertainties in drift properties and environmental forcing (wind, waves, and surface currents). Usually, the ... -
Beslutningsstøtte for miljøhensyn i operativ virksomhet
Voie, Øyvind Albert; Ommundsen, Atle; Messel, Espen; Flathagen, Joakim; Longva, Kjetil Sager (2008)Kunnskap om miljøkonsekvenser ved ulike militære aktiviteter gjør det mulig å inkludere hensynet til miljø i beslutningsfasen, noe som gir et bedre beslutningsgrunnlag. En viktig forutsetning for at Forsvaret skal unngå ... -
Low frequency models for littoral sound propagation - a comparison between a finite element model and a wave number integration model
Ommundsen, Atle; Kristiansen, Ulf R. (2005)Two different strategies for modeling sound propagation, exploring the Helmholz equation, in underwater acoustics are presented and compared, a nite element and a wave number integration model. The numerical models ... -
Operational METOC models at Norwegian Meteorological Institute (met.no)
Ommundsen, Atle; Jensen, Jan Kristian; Midtbø, Knut Helge; Engedahl, Harald (2008)The numerical forecasting models run by the Norwegian Meteorological institute (met.no) are crucial in providing meteorological and oceanographic services to the Norwegian armed forces. In this report our goal is to ...
