A Multisodar Approach to Wind Profiling

This paper presents the development of a multisodar Mode from a five-beam sodar whereby a wind speed vector is found flit sets of three acoustic beams tithe vertical beam is used. this mode enables the profiling of four wind speed measurements :Hound the soda, These multisodars can be used to investigate the spatial and temporal MIMIC of winds in both flat and complex terrain The spatial. temporal. and signal-to-noise qualities of the sodar signal in this mode are analyzed. and a metric for understanding the in homogeneity of the atmosphere through cross-correlating opposing multisodars is developed A driving factor for this work is developing the use of such systems in complex terrain, where experimental measurements are traditionally difficult and expensive
