基于多通道高朗伯特性的辐射测量技术研究
|
摘要
近年来大气气溶胶与日俱增,对全球气候和大气环境产生了巨大的负面影响,同时气溶胶的污染特性与臭氧层的破坏有密切关联,为对大气气溶胶、臭氧及太阳辐射剂量进行监测,本文提出一种新型大气探测辐射计的研制及测量方法,该方法研制的辐射计既可用于气候监测,又可用于农业监测。辐射计涵盖可见-红外谱段,同时拥有七个探测通道,它特有的三片式平面匀化器,可控制辐射剂量,保证双腔式探测器的高朗伯特性,经实验验证朗伯特性误差不超过2%。进行高精度辐射定标后,辐射计可获取精确的太阳辐射信号,进而反演出大气气溶胶光学厚度及臭氧浓度等参数,以此指导气候分析及农业生产。
In recent years,atmospheric aerosols have increased day by day,which has a huge negative impact on the global climate and atmospheric environment. At the same time,the pollution characteristics of aerosols are closely related to the destruction of the ozone layer. For the monitoring of atmospheric aerosols,ozone and solar radiation doses,a new manufacturing and measuring method of the atmospheric probing radiometer is proposed in this paper. The radiometer developed by this method can be used for both climate monitoring and agricultural monitoring. The radiometer covers the visible-infrared spectrum and has seven detection channels. Its unique three-piece planar diffuser controls the radiation dose and ensures high Lambertian properties of the dual-chamber detector. The experimental results show that the lambert error is no more than 2%. After high-precision radiometric calibration,the radiometer can obtain accurate solar radiation signals,and then reverse parameters such as optical thickness of atmospheric aerosol and ozone concentration to guide climate analysis and agricultural production.
