| 利用2004年秋冬季全国联网资料,给出中国19个典型区域大气气溶胶的光学厚度(AODλ=500nm)、Angstrom混浊系数(β)和Angstrom波长指数(α).结果表明,在青藏高原,海北、拉萨,AOD平均分别为0.09、0.12,β平均分别为0.05、0.13,α平均分别为1.09、0.06.东北地区,海伦、三江,AOD平均分别为0.14、0.15,β平均分别为0.04、0.06,α平均分别为2 |
| 英文摘要 |
| 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. |
