摘要：

Vertical profiles of atmospheric refractivity are indirectly measured at heights of up to 150 m above the ground using meteorological sensors located at 19 heights. The structure constant of the refractive index is calculated from data measured over a one-year period using its definition relation. Linear regression in heights is applied to a structure constant vertical dependence to obtain single and joint annual statistics of the near ground value of and of its vertical gradient in the lowest troposphere. Approximate probability models are given with being log-normal and the vertical gradient normally distributed.
