Water pollution on the Delta of Pearl River is increasingly serious and to command the fact of pollution is the key of the
control. A remote sensing model for water pollution base on single scattering is deduced in this paper. To avoid the
effect by turbidity of water, by analysis the characteristics of the energy composition of multiple scattering, a factor of
second scattering is deduced to build a double scattering model, and the practical arithmetic for the calculation of the
model is put forwarded and then used to the pollution remote sensing over the Pearl River Delta. The precision of the
result is validated by the synchronous measured data on water surface. The result of remote sensing showed that all of
the North River, East River and West River are polluted in Pearl River Delta, and the most serious pollution is take place
around Guang Zhou City and Dong Guan City.
The scattering and absorption of synthetic aerosol are the main represents of air pollution in remote sensing data. Synthetic aerosol is a referent of air pollution. In this paper, ground reflected spectrum is generalized as the composition of some basic components. Then reflectance model of every pixel is proposed with the variables of the ratios of ground surface basic components and the turbidity of synthetic aerosol. Using the model, turbidity of synthetic aerosol in the atmosphere can be calculated with multi-spectral remote sensing data. The model was applied in Shanghai district, and it was found that both of the area and extent of air pollution in the region are increasing quickly.
