Embodiment

[0104] Fig. 9 shows a measurement example of the atmospheric temperature distribution. It obtains an atmospheric temperature height distribution result by using the two Raman scattering signal intensities detected by channel 1 and channel 2, combined with the formula (2)-(6) algorithm.

[0105] Figure 10 shows an example of the distribution of relative humidity, which is detected by using a rotational Raman scattering signal of channel 1 (or channel 2) and a vibration Raman scattering signal of water vapor detected by channel 3, combined with formula (2), (15 )-(18) Calculate the water vapor density distribution, and then use the obtained atmospheric temperature (t) distribution, combined with formulas (19)-(21), to obtain an atmospheric relative humidity distribution.

Abstract

A method for determining parameter of atmospheric environment includes using laser radar determining system to receive backward scattering light of atmosphere, splitting received light to be various lights required by laser radar, carrying out analysis and treatment of data as per set program after photoelectric detection for realizing measurement on atmospheric environmental parameters such as temperature, steam density, airosol extinction coefficient, scattering coefficient, airosol optical thickness, visibility and depolarization ratio of non-spherical particle backward scattering light.

Description

technical field [0001] The invention belongs to the technical field of meteorological and environmental monitoring, and relates to a method for measuring meteorological and atmospheric environment parameters, in particular to a method for measuring the parameters by using an ultraviolet wavelength laser radar system for meteorological and atmospheric environment observation. Background technique [0002] In the field of atmospheric environment research, atmospheric temperature, water vapor density and atmospheric composition are important parameters for atmospheric research, such as: atmospheric temperature, water vapor density or relative humidity, and atmospheric aerosol extinction coefficient and scattering coefficient, aerosol optics Thickness and atmospheric visibility, depolarization ratio of backscattered light by non-spherical particles, etc. [0003] In the remote sensing detection of atmospheric parameters, atmospheric temperature, humidity and aerosol are three hi...
