Paper Abstract

The tropospheric SO2 in Pearl River delta region was firstly measured by airborne Multi Axis Differential Optical Absorption Spectroscopy in China on 10 December, 2008. The SO2 slant columns were derived with DOAS method in the wavelength from 310~ 325nm and the vertical columns were retrieved by radiative transfer model SCIATRAN. High values were observed near power plant regions with the vertical column density values higher than 8x1016molec./cm2 in the measurement. Combining with the meteorological data from local station the SO2 flux from the power plant was calculated, the emission flux of SO2 was about 2.59x1025molec./s. Over the city of Zhuhai, the observed SO2 vertical column density was 2.46x1016molec./cm2. This is in good agreement with ground-based MAX-DOAS of 2.62x1016molec./cm2 if the same aerosol parameter settings and a well mixed boundary layer of 1000 m is assumed.
