应用卫星遥感技术监测大气痕量气体的研究进展

大气污染是全球环境变化的焦点,传统的地面定点监测大气污染技术已经越来越不能满足科学研究和国家决策的需求,大尺度卫星遥感大气污染技术作为一种新兴的研究手段,可以得到大尺度、长时间序列的污染物时空分布特征和变化趋势,进而研究大气化学变化对全球气候和生物地球化学循环的影响。对卫星遥感大气痕量气体科学领域的发展和国际上使用的各类大气痕量气体传感器以及所取得的科研成果进行了全面的综述,结合中国地区的自身特点,提出我国利用卫星遥感技术研究大气成分的思路和未来开展科研工作的方向。

The Progress in Trace Gas Remote Sensing Study Based on the Satellite Monitoring

Atmospheric pollution has been the focus for the global environment change. The traditional ground-based monitoring of the atmospheric pollution can not satisfy the demand of science research and decision-making of government. The technology for trace gas remote sensing based on the satellite monitoring has played an important role in pollution monitoring, which can get the temporal and spatial variation of pollution in long-time series and the trend of the traoe gas change.So the study of global biogeochemical cycle and climate change can be done with these technologies and data. The instrument for trace gas monitoring on satellite and the data processing were reviewed. The prospects for trace gas remote sensing by our own satellite instruments and the trace gas research projects are also outlined.
