Work Package 2 : Experimental measurement campaign/ IOP #2
Achievement of the second Intensive Observation Period
UMRAE (Cerema/UGE) and et the Cerema laboraties of Clermont-Ferrand et and Blois carried out at the beginning of February the 2nd intensive observation campaign on the wind farm. An important acoustic and meteorological monitoring set-up allowed to complete the long-term campaign during one week. The installation of a second Lidar anemometer will allow to study the influence of wake effects on acoustic propagation.
This winter campaign completes the summer campaign.
