On the Relationship between the Aerosol Layer Height 2 the Mixed Layer Height Determined by Laser Radar an Low-Level Radiosonde Observations

Abstract

The relationship between the height of the stable layer and the height of the aerosol layer nearest to the ground on sunny days was examined using radiosonde and laser radar observations. Aerosol layer heights were determined by the normalized (aerosol) concentration gradient. Good correlation was found between the lowest-level stable layer and the lowest aerosol layer top (correlation coefficient=0.87) and also between the stable layer stability and the vertical gradient of the aerosol concentration at the aerosol layer top (correlation coefficient=0.78).
