Measurements and Analyses of Atmospheric Optical Properties over Tibetan Plateau

The data getting from a 10–channel solar photometer in Lhasa in June 1986 (during TIPEMX–1986) have been used to analyse the atmospheric optical properties over Tibetan Plateau. The results presented in this paper are as follows: The values of the total optical depth in Lhasa are only about half of those in Beijing, which indicates that atmospheric transparency over Plateau is good. The Chappuis bands of ozone can be used to retrieve the total ozone content of atmosphere in Plateau areas. The majority of aerosol size distributions over Lhasa can be best represented by the Junge distribution. The total moisture content of atmosphere not only relates to the circulation situation but depends on the moisture transportation.
