Measurement of Wind Near the Surface

A survey is presented of instrumentation suitable for measurement of wind near the surface of the earth by using in-situ techniques and further restricted to sensors that are operational. In this case, a sensor is deemed to be operational if it is commercially available. There is no discussion here of the systems that might be used to acquire, process, display, and store the sensor data. It is assumed that some sort of automatic data logging equipment would be used. Without special requirements such as need for high frequency response, low power consumption, etc., this treatment must be quite general and provides little detail. Also, without special restrictions, emphasis must be placed on conventional sensors that provide the bulk of wind data today.
