Abstract

The invention provides a method for measuring the height of an atmospheric boundary layer. An original algorithm based on a gravitational wave theory is adopted in the method, namely the gravitational wave gradient method is used for obtaining the height of the boundary layer and directly enabling aerosols which are distributed vertically under the effect of gravitational waves to be led to a theory of algorithms. The method is more suitable for obtaining the height of the real boundary layer of China high dust-haze pollution environment at present.

Description

technical field [0001] The invention relates to the technical field of atmospheric detection, in particular to a method for measuring the height of the atmospheric boundary layer, which can be widely used in weather forecasting, environmental protection, aviation safety and other related industries. Background technique [0002] In pollution incidents, the atmospheric boundary layer on which human beings rely is often the most polluted part of the atmosphere, and this phenomenon is more serious in cities and industrial areas. To predict the occurrence of air pollution events and understand the mechanism of air pollution events, it is necessary to study the physical and chemical processes in the atmospheric boundary layer, and the determination of the height of the atmospheric boundary layer occupies an important position in this process. [0003] Radiosonde observations are the traditional method for determining the height of the atmospheric boundary layer. However, the rou...
