国内外气溶胶观测网络发展进展及相关科学计划

ADVANCES IN AEROSOL OBSERVATION NETWORK AND CORRESPONDING SCIENCE PLAN

气溶胶是气候变化研究中的一个极大的不确定性因素,国内外在此方面开展了大量的观测和科学研究。本文首先对当前全球两大气溶胶观测网络,世界气象组织(WMO)的全球大气观测计划(GAW)和气溶胶自动观测网(AERONET)的组织、规模、设备、数据和气溶胶网络的规范作了介绍,并对近年来国际上的重大气溶胶科学计划的目标、实验方法、步骤作了介绍,说明观测网络的重要性。在此基础上对中国气溶胶观测网络的地位做了分析,并指出其在正在开展的中国气溶胶科学研究中的重要性。

Aerosol is one of the most uncertain factors in climate change study, and more observation and research worldwide pay much attention to its climate effect. There are two worldwide aerosol observation nets, one is WMO/GAW, and the other is AERONET. Some features about their organization, size, equipment, data, calibration and standards are introduced. Furthermore, some important aerosol scientific plans are introduced with their scientific objects, approach, measurements, and their dependence on aerosol observation net. In addition, the construction of China aerosol net （CAeroNet） is introduced and compared with other aerosol nets. Chinese Meteorological Administration builds CAeroNet, 20 observation sites over northern China, in order to monitor the dust storm and answer the climate effect of Asian aerosol. Through the ongoing Chinese aerosol science plans proposed by Chinese meteorological administration and national nature science foundation of China （NSFC）, CAeroNet will play an important role in Chinese aerosol science research.
