NOAA takes lidar delivery
Renewable NRG Systems sells two Windcubes units to US agency
The US National Oceanic and Atmospheric Administration (NOAA) has bought from Renewable NRG Systems two Windcube 200S 3D scanning doppler lidars.
NOAA’s chemical sciences division will use the units for a variety of measurement purposes, starting with the XPIA experiment at the Boulder Atmospheric Observatory (BAO) this month.
The Experiment is a field campaign that aims to quantify uncertainties in Doppler lidar measurements of wind conditions.
The project is being conducted with funding from the Department of Energy.
The lidar systems are being deployed in close proximity to the BAO’s heavily instrumented 300 metre meteorological tower.
Measurements of wind speed, wind direction, and velocity variance from well-calibrated sonic anemometers at six levels on the tower will be compared to measurements from the doppler lidars in order to assess the level of lidar measurement bias and uncertainty.
Later this year, the lidars will be deployed for the Wind Forecast Improvement Project (WFIP 2), another research campaign aiming to improve NOAA's short-term weather forecast models with regards to wind condition predictions that impact wind energy generation.
Renewable NRG Systems VP of global marketing & product management David Hurwitt said: “The Windcube scanning lidar series was designed with the twin goals of robustness and versatility in mind.
“This means that a single system can be adapted to a variety of research and operational uses in the fields of meteorology, air quality, and renewable energy.”
