Abstract

Ground-based, optical monitoring of the NO₂ column density and aerosol optical thickness is described. The instrument consists of a solar radiation spectrometer (SRS) and a conventional sunphotometer, both mounted on the same sun- tracker and operated automatically. From daytime measurements in Chiba, Japan during 1998 - 2000, variations of NO₂ and aerosol are analyzed. A correlation coefficient between NO₂ and aerosol is larger than 0.90 in winters. Because of the capability of simultaneous, real time measurement, this method is particularly suitable for air pollution studies in city areas.
