title: [Spatial-temporal distribution and variation of atmospheric SO2 concentration in Hangzhou].
abstract: The feasibility of diffusible sampler for monitoring SO2 in cantonal Hangzhou was studied, and its correlation equation with automatic monitoring was built. The distribution and variation of SO2 concentration in Hangzhou were analyzed and mapped. Position of SO2 concentration centre was changed along with different climate condition. SO2 concentration centre moved towards south in summer with higher diffusion capability of atmosphere and enlarged in winter with thicker inversion layer. Intension and frequency of acid rain were consistent with change tendency of SO2 concentration.
