Ecofys WTTS has upgraded its met mast with temperature gradient sensors from Ammonit. Validation measurements provide insight to the atmospheric stability and can greatly increase certainty in remote sensing wind measurement studies and improve the bankability of future wind energy projects.
In close collaboration with Ammonit Measurements GmbH based in Germany, the met mast was upgraded with six temperature sensors and a 3D sonic anemometer. The aim is to provide insights into the vertical temperature profile, which affects the atmospheric stability of the wind under consideration, and its specific impact on the accuracy of remote sensing devices. Measuring the temperature gradient is also part of the RealMe research project, with funding from the German Ministry of Environment. For a couple of years Ecofys WTTS has been testing the accuracy of remote sensing devices with its purpose-built met mast (120 meter) at the Ecofys WTTS test site in Lelystad in the Netherlands. To date, around 50 remote sensing devices have been successfully tested using this mast.
