Characteristics of ASL Turbulence Spectra and Cn2 using three-dimensional ultrasonic anemometer

Abstract

Abstract:

Velocity components and temperature data are measured using 50 Hz three-dimensional ultrasonic anemometer during January 2011. Characteristics of the turbulence spectra are calculated and analyzed under different stability over Hefei area. Comparing with other experiment results, curve fitting formulae, diverse instance of the power spectra peak position and tail raising of temperature spectra were obtained. And, two different refractive index structure parameter C_n² were measured and compared by hot wire anemometer and sonic anemometer(double-point and one-point method) above a uniform ground. The results obtained by two methods agree well.

Key words: turbulence, Spectra , three-dimensional ultrasonic anemometer, C_n²
