Wind Observation from Surface to Upper Layer

Measurement by Sonic Anemometer, Sodar, Boundary Layer Radar and MU Radar

Abstract

Measurement techniques of wind in the atmosphere are shown. Direct measurements of wind are realized only near the surface A sonic anemometer can measure the fine structure in a atmospheric boundary layer and evaluate the turbulent transfer mechanism. Remote sensing techniques using the sound and radio wave are utilized to survey the wind structure in the upper layer. Recent measurement systems are introduced briefly.
