SODAR (SOund Detection And Ranging) uses sound energy to probe the lower atmosphere. By analyzing the Doppler frequency shift of the backscattered sound, the profile of the wind speed and direction up to 300 m is determined.
Complex terrain leads to complex wind profiles. FLY! animations and terrain profiling techniques can improve understanding of wind flow in complex terrain. Here is an example animation (3.5 Mb). IEDat uses PCIGeomatics, Inc. software for GIS/Remote Sensing data analyses.
Long-term monitoring of wind speed, wind direction, and wind shear are essential for wind resource assessment. IEDat offers monitoring and data analysis for the wind energy community.
