Boundary Layer Structure Measured by Wind-profile Radar and Lidar

摘要

2008 ARM experiment in ShouXian China used a variety of instruments to explore atmospheric multiscale detection.This article selected the data of wind-profile radar,micro-pulse lidar and traditional sounding,focusing on primary analysis on the variation characteristics of atmospheric boundary layer structure analyzed preliminarily.Lidar backscatter is proportional to aerosol content (and some molecular scatter) in the boundary layer(Cohn and Angevine 2000;He,Mao et al.2006),and wind profiler backscatter depends on the refractive index structure (moisture gradients and turbulence strength)(Angevine,White et al.1994;Bianco and Wilczak 2002;Bianco,Wilczak et al.2008).
