Analysis of multiple scattering errors in LISST-VSF volume scattering function measurements using Monte Carlo simulations and experimental data
Ugulen, Håvard Stavn; Sandven, Håkon; Hamre, Børge; Kristoffersen, Arne Skodvin; Sætre, Camilla (Journal article; Peer reviewed, 2021)A Monte Carlo algorithm has been developed to investigate the effects of multiple scattering on the volume scattering function measured by the LISST-VSF instrument. The developed algorithm is compared to experimental results ... -
Challenges, limitations, and measurement strategies to ensure data quality in deep-sea sensors
Skålvik, Astrid Marie; Sætre, Camilla; Frøysa, Kjell Eivind; Bjørk, Ranveig Nygaard; Tengberg, Anders (Journal article; Peer reviewed, 2023-04-06)In this paper we give an overview of factors and limitations impairing deep-sea sensor data, and we show how automatic tests can give sensors self-validation and self-diagnostic capabilities. This work is intended to lay ... -
Characterisation of Single Wind Turbine Wakes with Static and Scanning WINTWEX-W LiDAR Data
Kumer, Valerie-Marie; Reuder, Joachim; Svardal, Benny; Sætre, Camilla; Eecen, Peter (Peer reviewed; Journal article, 2015)With further development of LiDAR technology wake measurements by use of LiDAR became of common interest in the wind energy community. To study new measurement strategies of scanning and nacelle LiDARs, in combination with ... -
Directional wave measurements from navigational buoys
Sætre, Camilla; Tholo, Harald; Hovdenes, Jostein; Kocbach, Jan; Hageberg, Anne Ansnes; Klepsvik, Inge; Aarnes, Ole Johan; Furevik, Birgitte Rugaard; Magnusson, Anne Karin (Journal article; Peer reviewed, 2022)In-situ wave measurements are often required by marine industry standards and for verification of coastal wave forecasts. Obtaining wave measurements is costly and it would be advantageous to utilize existing platforms ... -
