| 摘 要： | With the multichannel radiometer of visible and infrared band, ground-based observationsof the intensity of solar spectrum and the atmospheric optical thickness have been made andthe method of remote sensing atmospheric aerosol and water vapour content have been studied.With the radiometer(seven channels of 0.5--1.06μ), observations have been made for morethan one year in Beijing. The atmospheric water vapour content obtained from remote sensingis in accord with that from radiosonde data. In this paper, the characteristics of atmosphericaerosol and total water vapour content are discussed, and the influences of aerosol and thewater vapour on the atmospheric optical thickness and the relationship between them in thewater absorption region are also treated with.
