WAFFLE Experiment

Elliot Simon & Guillaume Lea
The WAFFLE campaign is a short field experiment originally conducted to provide data for initial investigations into minute-scale wind forecasting.
A single long-range scanning lidar was deployed behind DTU's V52 research wind turbine at Risø test site in Denmark. Plan position indicator (PPI) scans were performed facing west to measure the dominant inflow to the test site.
This dataset was used in an applied workshop at the EAWE PhD seminar in Belgium. The presentation file and code...

Numerical models for the design and analysis of heat pumps with zeotropic mixtures

Benjamin Zühlsdorf, Brian Elmegaard & Jonas Kjær Jensen
The work presents numerical models for the design and analysis of heat pump cycles with pure and mixed working fluids. The models are suitable for working fluid screenings for pure and mixed working fluids and offer possibilities for a detailed analysis of the heat pump cycle.

Perdigão-2015: multi-lidar flow mapping over the complex terrain site including the wind turbine inflow and wake measurements

Nikola Vasiljevic, Nikolas Angelou & Guillaume Lea
This dataset has been recorded by three long-range WindScanners and three short-range WindScanners during the Perdigão 2015 campaign. For the campaign which took place in central Portugal near the village of Perdigão three scanners were located on two mountain ridges that run in parallel for about 2 km. The scanners carried out six synchronized scanning scenarios: a transect scan perpendicular to the ridges; a virtual mast within the valley; a scan following a transect 80...

Perdigão-2017: multi-lidar flow mapping over the complex terrain site

Robert Menke, Jakob Mann & Nikola Vasiljevic
This dataset has been recorded by eight long-range WindScanners that were deployed during the Perdigão 2017 campaign. For the campaign which took place in central Portugal near the village of Perdigão eight scanners were located on two mountain ridges that run in parallel for about 2 km. The scanners carried out three synchronized scanning scenarios: transect scans at three positions perpendicular to the ridge with two scanners at two transects and one transect with four...

Østerild Balconies Experiment (Phase 2)

Elliot Simon & Nikola Vasiljevic
This dataset includes measurements from the two scanning lidars which were deployed in phase 2 of the Balconies Experiment at DTU’s Østerild Test Centre in Western Denmark during the summer of 2016.
Two DTU long-range WindScanners were installed on purpose-built platforms attached to instrumented aircraft warning towers at the north and south ends of the test site at a height of 200 m above ground level (AGL). The lidars were configured to perform 90 degree...

LASCAR Experiment

Elliot Simon & Guillaume Lea
The LASCAR campaign is a field experiment originally conducted to provide data for building and testing lidar based minute-scale forecasting models. The measurement goal was to capture the dominant westerly inflow to the Risø test site.
This was achieved by deploying 3 scanning lidars in a compact area surrounding building 313 at Risø. One unit (Sirocco) was stationed on the roof of the building and performed fast (13 s/scan) repeating PPI scans facing west with an...

A data set for comparison of sector-scan and dual-Doppler retrievals of horizontal wind speed and wind direction made using multiple scanning lidars

Nikola Vasiljevic, Guillaume Lea & Michael Courtney
Acquiring actual wind velocities at potential wind farm sites is an important way of reducing the uncertainty in estimates obtained from meso-scale models. Since costs of offshore meteorological masts are high, ground based scanning lidars installed on-shore could be a cost-attractive way of acquiring necessary information about the wind velocity in near-coastal regions (up to about 10km). One important decision is whether to use one sector-scanning scanning lidar or two separated scanning lidars employing dual-Doppler...
