The COTUR (Measuring coherence and turbulence with Lidars) campaign was a one-year measurement campaign from
March 2019 until March 2020 at Obrestad Lighthouse in southwestern Norway. The instrumentation consisted of
three scanning lidars, one vertical wind profiler and a passive microwave radiometer.
All three scanning lidars performed line-of-sight (LOS) scans, i.e. scans with a fixed azimuth and elevation
angle. The azimuth angles correspond to the mean wind direction as determined by the last 10 minute average wind
direction given by the vertical wind profiler. Three pre-defined elevation angles were used during the entire
campaign. The laser beams of the three scanning lidars were consistently orientated parallel to each other and
the measurements were time synchronized. The main purpose of the collected data is to evaluate the turbulence
and the horizontal coherence for different lateral laser beam separation distances.
The project partners and data owners are Equinor, NORCE, University of Bergen and University of Stavanger.
Access to the data is restricted to the data owners. For questions about data access, please contact an
