| 摘 要： | 基于被动差分光学吸收光谱(DOAS)算法,使用车载被动DOAS技术在测量污染源排放通量时,由于云的多次散射影响,导致污染源排放通量的计算误差.特别对于像NO2这样的整层分布气体,由于低层云的出现造成多次散射增强使得NO2浓度显著升高,造成在计算污染源排放通量时产生较大误差.针对此问题,提出在车载DOAS污染源排放通量监...

| Abstract: | A large calculation error of pollutant emission flux occurs due to the influence of multiple scattering when we utilize the mobile differential optical absorption spectroscopy(DOAS),which is based on the passive differential optical absorption spectroscopy,to measure the pollutant source.The concentration of NO2 that lies in the total layer increases significantly because of multi scattering in the lower atmospheric cloud.This results in large computing error of NO2 emission flux.To solve this problem,a new... |
