Abstract:Based on the meteorological data from 38observation stations of year 1980~2009and the Chinese urban API (Air pollution Index) data of 2001~2009, the haze distributions over the Yangtze River Delta region for the period of 1980~2009 are characterized. The extinction coefficients for all observation sites were calculated with double correction.The corrected extinction coefficients varied seasonally from the peak in winter to the bottom in summer. Over the 30years, there was a significantly increasing trends in haze days. Horizontal visibility, haze days, dry coefficient and API of three urban stations of Nanjing, Hangzhou, Hefei were analyzed. visibility was negative correlated with API in the haze days, and the correlation coefficients gradually increased in higher relative humidity.
