Abstract
Results of ground-based remote sensing of atmospheric species conducted in Beijing from October 1989 to December 1990 for several periods of time on clear days are presented. Total columns of O3, NO2, NO3, and the slant column of O3 and NO2 were obtained by solar and skylight spectrophotometer (SSS) through direct sun/moon and zenith sky measurements, respectively. Results of aerosol measurements performed by SSS in Beijing are also reported. Beginning on October 25, 1990, total columns of O3, SO2, and UVB radiations were measured by Brewer spectrophotometer. It is found from the wintertime measurements that total O3 increases with time while UVB radiation decreases. There is a 14-d period for the variation of O3 amounts. The amount of SO2 increases during the hot season in Beijing.
