Abstract
A He-Ne laser based profiler for atmospheric wind measurements across a laser beam is compared to an instrument using incoherent infrared light from a photodiode tranmitter. Both optical crosswind profilers use the scintillation of the light source to measure the average wind across the light path. Several techniques to derive the wind velocity from the normalized time- lagged covariance function of two narrow spaced receivers are tested. Nine conventional wind sensors were placed along a 1 km long test path to get a reference wind distribution for the instruments. The tests performed over a wide variety of different weather situations with low to high wind velocities and different turbulent conditions reveal a good performance of the IR scintillometer.
