Publikováno v: Remote Sensing, Vol 14, Iss 15, p 3576 (2022)

The full-width at half-maximum or probe length of the Lorentzian weighting function of continuous-wave Doppler lidars increases quadratically with the focus distance, which results in a deterioration in the spatial resolution of measurements. What is

Editorial for the Special Issue 'Remote Sensing of Atmospheric Conditions for Wind Energy Applications'

Autor: Charlotte Bay Hasager, Mikael Sjöholm

Publikováno v: Remote Sensing, Vol 11, Iss 7, p 781 (2019)

This Special Issue hosts papers on aspects of remote sensing for atmospheric conditions for wind energy applications. The wind lidar technology is presented from a theoretical view on the coherent focused Doppler lidar principles. Furthermore, wind l

Publikováno v: Meteorologische Zeitschrift, Vol 18, Iss 2, Pp 135-140 (2009)

The goals are to compare lidar volume averaged wind measurement with point measurement reference sensors and to demonstrate the feasibility of performing 3D turbulence measurements with lidars. For that purpose three pulsed lidars were used in starin

Modern large wind turbines require high-resolution wind measurements as input to aerodynamic and aeroelastic simulations for modelling and validation purposes. Within the HighRe project, we aim at studying the aerodynamic effects at high Reynolds num

Investigation of the turbulent three-dimensional wind field in the near-wake of a full-scale wind turbine using synchronized scanning wind lidars

Autor: Nikolas Angelou, Mikael Sjöholm, Torben Mikkelsen

The objective of this work is to enhance the understanding of the mean wind and turbulence characteristics in the wake of a full-scale wind turbine. Here, we present observations of the three-dimensional wind vector in the near wake of a wind turbine
