Automated Measurements of Whitecaps on the Ocean Surface from a Buoy-Mounted Camera
Paskyabi, Mostafa Bakhoday; Reuder, Joachim; Flügge, Martin (Peer reviewed; Journal article, 2016-12)We quantify the percentage of sea surface covered by whitecaps from images taken by a non-stationary camera mounted on a moored buoy using an Adaptive Thresholding Segmentation (ATS) method and an Iterative Between Class ... -
Characterization of the SUMO Turbulence Measurement System for Wind Turbine Wake Assessment
Båserud, Line; Flügge, Martin; Bhandari, Anak; Reuder, Joachim (Peer reviewed; Journal article, 2014)The remotely piloted aircraft system (RPAS) SUMO (Small Unmanned Meteorological Observer) has been equipped with a miniaturized 5-hole probe sensor system for measurement of the 3-dimensional flow vector with a temporal ... -
Comparison of direct covariance flux measurements from an offshore tower and a buoy
Flügge, Martin; Bakhoday Paskyabi, Mostafa; Reuder, Joachim; Edson, James B.; Plueddemann, Albert J. (Peer reviewed; Journal article, 2016-05)Direct covariance flux (DCF) measurements taken from floating platforms are contaminated by wave-induced platform motions that need to be removed before computation of the turbulent fluxes. Several correction algorithms ... -
The COTUR project: remote sensing of offshore turbulence for wind energy application
Cheynet, Etienne; Flügge, Martin; Reuder, Joachim; Jakobsen, Jasna Bogunovic; Heggelund, Yngve; Svardal, Benny; Saavedra Garfias, Pablo Andres; Obhrai, Charlotte; Daniotti, Nicolo; Berge, Jarle; Duscha, Christiane Anabell; Wildmann, Norman; Onarheim, Ingrid Husøy; Godvik, Marte (Journal article; Peer reviewed, 2021)The paper presents the measurement strategy and data set collected during the COTUR (COherence of TURbulence with lidars) campaign. This field experiment took place from February 2019 to April 2020 on the southwestern coast ... -
Predictive Capability of WRF Cycling 3DVAR: LiDAR Assimilation at FINO1
Paskyabi, Mostafa Bakhoday; Flügge, Martin (Journal article; Peer reviewed, 2021)In this study, we assess tentatively the predictive capability of the Weather Research and Forecasting (WRF) model and its Three-Dimensional Variational (3DVAR) system. We study the impact of LiDAR data assimilation on ... -
Preliminary results of the NORCOWE Direct Covariance Flux System for Ship based measurements
Flügge, Martin; Reuder, Joachim (Peer reviewed; Journal article, 2013)To cover the increased demand of renewable energy the development of offshore wind turbines that can be placed in deep water has started. Model results from Sullivan et al. [2] indicate that the ocean has the ability to ... -
Sensor movement correction for direct turbulence measurements in the marine atmospheric boundary layer
Flügge, Martin; Reuder, Joachim; Edson, James (Peer reviewed; Journal article, 2012)Understanding of the turbulent exchange processes between the ocean and the overlying atmosphere is essential for wind shear and turbulence structure of the Marine Atmospheric Boundary Layer (MABL). This is highly relevant ... -
Wave–induced characteristics of atmospheric turbulence flux measurements
Paskyabi, Mostafa Bakhoday; Flügge, Martin; Edson, James B.; Reuder, Joachim (Peer reviewed; Journal article, 2013)In this paper, we present the air–sea flux of momentum obtained with the eddy correlation method applied to data measured from a moored discus buoy deployed approximately 600 m off a research Air Sea Interaction Tower at ... -
Wind Stress in the Coastal Zone: Observations from a Buoy in Southwestern Norway
Flügge, Martin; Bakhoday Paskyabi, Mostafa; Reuder, Joachim; El Guernaoui, Omar (Peer reviewed; Journal article, 2019-08-26)Several studies have focused on the investigation of the wind stress in open ocean conditions where coastal processes were negligible. However, the direction and magnitude of the wind stress vector in coastal areas are ...
