The Doppler SODAR measures vertical profiles of wind and turbulence, monitors inversion layers and derives stability classes in height ranges 15 m … ≥ 1000 m. A powerful WINDOWS PC controls the sounding and processes and transfers the data. The Doppler SODAR is a reliable, cost efficient tool for operational set ups and short term campaigns. The low power version of the Doppler SODAR PCS.2000 fits perfectly for mobile stand-alone profiling at remote sites.
