国际新一代对地观测系统在气溶胶遥感方面的应用

The Development of Atmospheric Aerosol Investigation by Earth Observation System

大气气溶胶在很多生物地球化学循环中具有重要作用,但是由于它的来源广泛并且具有很大的时空变化,难以在全球范围内精确、实时确定气溶胶的性质、组成及时空分布,因而对大气气溶胶的研究依赖于监测手段的发展。对大气气溶胶实验观测的观测方法和测量仪器有很多,而对地观测卫星利用其特有的优势,可以实现对气溶胶的大范围、实时探测,促进了大气气溶胶这一边缘学科的研究发展。简要回顾了对地观测系统(E arth Observ ing System)的发展历程,然后介绍了对地观测卫星遥感气溶胶的发展及现状,对国际新一代对地观测系统在气溶胶遥感方面的应用现状做了详细的描述和总结。

Atmospheric aerosols impact the geochemistry,climate and environment.But it is difficult to study the distribution of the spectrum,the chemical composition and the circulation of atmospheric aerosols in detail,due to the indetermination of aerosol source and distribution in atmosphere.As a result,the investigation of the aerosol dependents on the development of monitoring manners.Many detection means and instruments were adopt on aerosols research,especially the application of satellites remote sensing.Taking advantage of their space location,satellites can obtain the global,real-time,precise imagery,which promote the evolution of aerosol learning.In the paper,the evolution of the earth observation system,and the application of EOS data and information on aerosol investigation was presented.At the end,it was evaluated that the present status and major achievements of international atmospheric aerosol research based on the EOS program.
