  • Arctic climate change: observed and modelled temperature and sea-ice variability 

    Johannessen, Ola M.; Bengtsson, Lennart; Miles, Martin W.; Kuzmina, Svetlana I.; Semenov, Vladimir A.; Alekseev, Genrikh V.; Nagurnyi, Andrei P.; Zakharov, Victor F.; Bobylev, Leonid P.; Pettersson, Lasse H.; Hasselmann, Klaus; Cattle, Howard P. (Blackwell Munksgaard, 2004-07-09)
    Changes apparent in the arctic climate system in recent years require evaluation in a century-scale perspective in order to assess the Arctic's response to increasing anthropogenic greenhouse-gas forcing. Here, a new set ...
  • Characterization of the coastal marine atmospheric boundary layer (MABL) for wind energy applications 

    Christakos, Konstantinos (The University of Bergen, 2013-06-03)
    The main problem for the characterization of marine atmospheric boundary layer is the lack of available offshore measurements in relevant altitude range up to 200 m. Remote sensing meteorological instruments such as LIDARs ...
  • Coastal ocean fronts and eddies imaged with ERS 1 synthetic aperture radar 

    Johannessen, Johnny A.; Shuchman, Robert A.; Digranes, G.; Lyzenga, D. R.; Wackerman, C.; Johannessen, Ola M.; Vachon, P. W. (American Geophysical Union, 1996-03-15)
    ERS 1 C band synthetic aperture radar (SAR) data were collected during the Norwegian Continental Shelf Experiment (NORCSEX) both in November 1991 during the ERS 1 commissioning phase and at different seasons in 1992 and ...
  • Coastal wind field retrievals from ERS synthetic aperture radar images 

    Korsbakken, E.; Johannessen, Johnny A.; Johannessen, Ola M. (American Geophysical Union, 1998-04-15)
    A unique series of European Remote Sensing Satellite (ERS) 1 and 2 C band synthetic aperture radar (SAR) images was obtained off the southern coast of Norway during the Coast Watch’95 experiment in September 1995. In this ...
  • An ERS 1 synthetic aperture radar image of atmospheric lee waves 

    Vachon, P. W.; Johannessen, Ola M.; Johannessen, Johnny A. (American Geophysical Union, 1994-11-15)
    An ERS 1 synthetic aperture radar (SAR) image of the island Hopen shows a distinct 7.6-km wavelength wave phenomenon near the island. This wave phenomenon is interpreted as the surface imprint on open water of atmospheric ...
  • Resistance and heat-transfer laws for stable and neutral planetary boundary layers: old theory advanced and re-evaluated 

    Zilitinkevich, Sergej S.; Esau, Igor N. (Royal Meteorological Society, 2005-07)
    The planetary boundary layer (PBL) resistance and heat-transfer laws express the surface fluxes of momentum and heat through the PBL governing parameters. Since the late sixties, the dimensionless coefficients (A, B and ...
  • Toward an optimal inversion method for synthetic aperture radar wind retrieval 

    Portabella, M.; Stoffelen, A.; Johannessen, Johnny A. (American Geophysical Union, 2002-08-01)
    In recent years, particular efforts have been made to derive wind fields over the oceans from synthetic aperture radar (SAR) images. In contrast with the scatterometer, the SAR has a higher spatial resolution and therefore ...
