探讨气候变化的新热点:大气气溶胶的气候效应

气溶胶的气候效应是近年来研究的热点问题。针对这一问题已开展过许多观测研究和模式研究。但是由于气溶胶问题的复杂性以及对气溶胶的观测历史短，至今尚缺少全球范围的气溶胶系统观测资料，所以目前气溶胶的辐射强迫仍是个很不确定的量。这直接影响对全球气候变化的预测。目前国内外正在加强这方面的研究工作，并且有了一些初步的结果。概述了近期国内外对气溶胶的气候效应的研究状况及结果，介绍了今后国际上将要在这一领域开展的研究工作。

THE HOT DISCUSSION ABOUT CLIMATE CHANGE:THE CLIMATE EFFECTS OF AEROSOLS

Atmospheric aerosols can affect climate by scattering and absorbing solar radiation. There have been a lot of observing and modeling researches about the issue. But understanding of their influence on climate change is beset with uncertainty, for the observation history of aerosol is short and until now there has been no systematically observing data about global aerosol. So far many efforts have been made for improving our know ledge. We introduce some of recent results from observing and modeling researches about aerosols and the further work which will be carried out or will be worth being carried out.
