Analysis of Ozone and Aerosol Data Measured at Dabie Mountain and Hefei Suburb Regions

Yuexi County, located in the Dabie Mountain area, is a typical mountain. The ozone analyzer EC9810, multi-channel optical particle counter OPC-06 and instrument of carbon black are used to measure the atmospheric parameters from May 22 to June 10, 2009. The ozone and aerosol size distribution and their daily variation are obtained. Those data are compared with the ones measured at Hefei. The comparison indicates: (1) ozone level in Hefei is significantly higher than that at Changpu Town in Yuexi County; (2) aerosol types are different between Hefei and Changpu; (3) aerosol absorption coefficient is significantly higher in Hefei than that in the mountain, and aerosol absorption wavelength index is smaller in Hefei than that in Changpu.
