The requirements for a ground-based wind shear sensing system are developed. System coverage, accuracy, resolution, and data update rate are treated in detail. The differing requirements for synoptic shear conditions and thunderstorm-associated shears are discussed. Several candidate sensing systems are considered. The hybrid CW/pulsed laser is discussed in detail because of its potential for providing advance warning for all shear conditions. Propagational implications are developed. A system concept is outlined which provides the Framework for a future operational system.
