Atmospheric aerosol optical depth (AODλ=500nm), Angstrom turbidity coefficient(β) and Angstrom wavelength exponent (α) are obtained using the CERN sun hazemeter network from Aug to Dec, 2004. The results are as follows: At the Tibetan Plateau, Haibei and Lhasa, the mean of AOD is 0.09, 0.12; the mean of β is 0.05, 0.13; the mean of α is 1.09, 0.06, respectively. At the Northeast of China, Hailun and Sanjiang, the mean of AOD is 0.14, 0.15; the mean of β is 0.04, 0.06; the mean of α is 2.32, 1.58, respectively. At the desert region of North China, e.g. Fukang, Shapotou and Eerduosi, the range of averaged AOD is from 0.17 to 0.32; the range of averaged β is from 0.09 to 0.19; the range of averaged α is from 0.68, to 1.28. At the forest areas, e.g. Changbai Mountain, Beijing forest and Xishuangbanna, the range of averaged AOD is from 0.19 to 0.42; the range of averaged β is from 0.12 to 0.19; the range of averaged α is from 1.11 to 1.25. At agriculture areas, e.g. Shenyang, Fengqiu , Taoyuan and Yanting, the range of averaged AOD is from 0.34 to 0.68; the range of averaged β is from 0.18 to 0.38; the range of averaged α is from 0.97 to 1.39. At the littoral areas and the lake of East China, e.g. Jiaozhou Bay, Shanghai City and Tai Lake, the range of averaged AOD is from 0.49 to 0.68; the range of averaged β is from 0.21 to 0.29; the range of averaged α is from 1.24 to 1.37. At the inland cities, Beijing City and Lanzhou City, the mean of AOD is 0.47, 0.81; the mean of β is 0.20, 0.45; the mean of α is 1.66, 0.89, respectively. The variations of aerosol properties at nineteen stations are explained in the paper.
