| 摘 要： | 本文使用北京地区不同时期（2009年1月和2013年1月）的地基气溶胶观测资料，估算了灰霾天气的人为气溶胶光学厚度，在此基础上结合气溶胶光学参数进行了对比分析。结果表明：（1）2013年1月人为气溶胶光学厚度（440 nm）较2009年1月有所增加，月平均值分别为0.88和0.44；（2）2013年1月灰霾污染中人为气溶胶占统治地位的天数比例是86.7%，高于2009年1月的62.5%；（3）2013年1月人为成分在气溶胶光学厚度（440 nm）中的贡献平均达88%，说明灰霾污染主要是由人为气溶胶造成的。

| Abstract: | In this study, we estimated the anthropogenic aerosol optical depth in haze using the ground-based aerosols observation in different periods in Beijing (January 2009 and 2013), then compared and analyzed them with retrieved aerosol optical properties. The results showed that: (1) the monthly averaged anthropogenic aerosol optical depth (440 nm) of January 2009 and 2013 were 0.88 and 0.44. (2) The proportion of the days when anthropogenic aerosol optical depth was dominant in January 2013 was 86.7%, more than that of January 2009 (62.5%). (3) The ratio of the total optical depth (440 nm) was about 88% in January 2013, indicating the crucial role of anthropogenic aerosol in haze pollution. |
