Abstract

The Atmospheric Boundary Layer (ABL) is the most accessible layer of Earth's atmosphere. It is also the most important layer to the atmospheric research. We measure the wind arid turbulence profile in the ABL with a Doppler Sodar which can cover from 30m up to 300 500m, and a Boundary Microwave Wind Profiler, which can cover from 1OOm up to 3000m. With all these experimental sets, we can get the continuous profiles of wind, refractive index structure function parameter, C2 and the wind structure function C2 from the ground up to 3000m. From the results of these sets, we can obtain the characteristics of profiles and diurnal variations.
