      Raj, Roshin Pappukutty; Andersen, Ole Baltazar; Johannessen, Johnny Andre; Benjamin, Gutknech; Chatterjee, Sourav; Rose, Stine; Bonaduce, Antonio; Horwath, Martin; Ranndal, Heidi; Richter, Kristin; Palanisamy, Hindumathi; Ludwigsen, Carsten; Bertino, Laurent; Nilsen, Jan Even Øie; Knudsen, Per; Hogg, Anna E.; Cazenave, Anny; Benveniste, Jérôme (Journal article; Peer reviewed, 2020)
      Sea level change is an important indicator of climate change. Our study focuses on the sea level budget assessment of the Arctic Ocean using: (1) the newly reprocessed satellite altimeter data with major changes in the ...
    • Characterization of turbulence in wind turbine wakes under different stability  conditions from static Doppler LiDAR measurements 

      Kumer, Valerie-Marie; Reuder, Joachim; Eikill, Rannveig (Peer reviewed; Journal article, 2017-03-05)
      Wake characteristics are of great importance for wind park performance and turbine loads. While wind tunnel experiments provided a solid base for the basic understanding of the structure and dynamics of wind turbine wakes, ...
    • An Evaluation of the EnKF vs. EnOI and the Assimilation of SMAP, SMOS and ESA CCI Soil Moisture Data over the Contiguous US 

      Blyverket, Jostein; Hamer, Paul David; Bertino, Laurent; Albergel, Clement; Fairbairn, David; Lahoz, William A. (Peer reviewed; Journal article, 2019-02-26)
      A number of studies have shown that assimilation of satellite derived soil moisture using the ensemble Kalman Filter (EnKF) can improve soil moisture estimates, particularly for the surface zone. However, the EnKF is ...
    • Monitoring Soil Moisture Drought over Northern High Latitudes from Space 

      Blyverket, Jostein; Hamer, Paul David; Schneider, Philipp; Albergel, Clement; Lahoz, William A. (Peer reviewed; Journal article, 2019-05-20)
      Mapping drought from space using, e.g., surface soil moisture (SSM), has become viable in the last decade. However, state of the art SSM retrieval products suffer from very poor coverage over northern latitudes. In this ...
    • 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 ...
