    • Influence of synoptic weather patterns on solar irradiance variability in northern Europe 

      Parding, Kajsa; Liepert, Beate G.; Hinkelman, Laura M.; Ackerman, Thomas P.; Dagestad, Knut-Frode; Olseth, Jan Asle (Peer reviewed; Journal article, 2016-05)
      Observations have revealed strong variability of shortwave (SW) irradiance at Earth’s surface on decadal time scales, referred to as global dimming and brightening. Previous studies have attributed the dimming and brightening ...

    • Multi-scale variability of winds in the complex topography of southwestern Norway 

      Jonassen, Marius Opsanger; Ólafsson, Haraldur; Reuder, Joachim; Olseth, Jan Asle (Peer reviewed; Journal article, 2012-01-02)
      Multi-scale variability of winds in the complex terrain of southwestern Norway is investigated using up to 20yr of observations from nine automatic weather stations and reanalysis data. Significant differences between the ...

    • Satellite and Ground Observations of Snow Cover in Tibet during 2001–2015 

      Basang, Droma; Barthel, Knut; Olseth, Jan Asle (Peer reviewed; Journal article, 2017-11-22)
      The seasonal snow cover of the Tibetan Plateau exerts a profound environmental influence both regionally and globally. Daily observations of snow depth at 37 meteorological stations in Tibet and MODIS eight-day snow products ...

    • Simulations of the Bergen orographic wind shelter 

      Jonassen, Marius Opsanger; Ólafsson, Haraldur; Valved, Aslaug Skålevik; Reuder, Joachim; Olseth, Jan Asle (Peer reviewed; Journal article, 2013-10-10)
      Even though the coast of western Norway is very windy, the centre of Bergen is rather calm. To gain further understanding of this wind shelter, we study the flow in the complex topography of Bergen during two south-westerly ...
