Abstract
The German-Israeli intercomparison experiment on the investigation of vertical profiles of horizontal wind speed and optical turbulence in the lower atmospheric boundary layer from 4th to 7th May 2015 was characterized by frontal activity in the atmosphere. The newly developed remote LIDAR-device of the Soreq institute for the investigation of the vertical wind and turbulence field was compared to the routinely performed measurements at the VerTurM (Vertical Turbulence Measurements) field site in Meppen, Germany. The long-term experiment VerTurM is focused on measurements of the optical turbulence and comprises scintillometer measurements close to the ground (1.15 m height), sonic anemometer measurements on a tall tower at 4 m, 8 m, 32 m, and 64 m and a SODAR-RASS-system. The temporal development of the vertical profiles of horizontal wind speed and optical turbulence Cn 2 during the frontal passage is investigated. Additional radiosonde measurements were performed to characterize the boundary layer height during the day.
