摘要
由于工业活动的影响，对流层气溶胶含量明显增加。他们通过直接吸收和反射太阳辐射以及改变其它辐射强迫因子（云、臭氧）的大小间接影响地气系统的能量收支。近年来研究表明：人类活动产生的气溶胶具有与ＣＯ２温室气体大小相当、符号相反的辐射强迫效应。他们在全球或区域范围内削弱温室气体的变暖趋势，对气候变化造成很大的影响。文章就人为气溶胶辐射强迫及气候效应近年来的研究状况做了介绍。
Since pre industrial times, the concentration of atmospheric aerosols increase obviously. Aerosols influence the energy budget of earth atmosphere system directly by absorbing and back scattering incoming solar radiation, and indirectly by changing the magnitude of other radiative forcing factors,such as cloud, ozone, et al. Recent studies present that anthropogenic aerosol radiative forcing is comparable but opposite in sign to the current greenhouse forcing caused by increase of CO 2 and then reduce the warming tendency by increased greenhouse gases in region and in globe, and play an important role in climate change.In this paper,we introduce the advance in the study of aerosol radiative forcing and its climate response.
