Chapter 7

Estimation of the Lower Atmospheric Turbulence Parameters by Sodar-Rass Unit and Sonic Anemometer

Renato Ricci, Roberta Cocci Grifoni and Marco Mazzieri

Abstract

Purpose of this chapter was to analyze the planetary boundary layer (PBL) using remote sensing tools. Sodar techniques allowed us to obtain speed and wind direction profiles from a height ranging from 30/40 m. to 1000 m. The SODAR (Sound Detection And Ranging) is, in fact, an alternative to the use of cup anemometers and offers the possibility of measuring both the wind speed distribution with height and the wind direction. In particular, these instruments play a key role both to assess the wind resource in a specific area and to estimate the alteration of the wind field caused by the complex orography of the region.
