| 摘 要： | 综合分析了国际上卫星遥感观测大气二氧化碳（CO2）含量的主要技术与方法,讨论了现有星载大气CO2探测器（传感器）的主要理论基础、反演方法,归纳了仪器的主要性能指标、观测方式和观测目标,分析了影响CO2遥感精度的主要因素。具体研究下列3类星载CO2探测器：① 技术相对成熟的、观测要素既包含CO2也包含其他微量气体的综合性星载被动探测仪器,例如大气红外垂直探测仪(AIRS)、大气制图扫描成像吸收光谱仪(SCIAMACHY)、超高光谱红外大气探测干涉仪(IASI)；② 针对大气中CO2混合比或者对流层下层CO2含量进行专门观测的星载被动探测器：极轨碳观测卫星(Orbiting Carbon Observatory,OCO)和温室气体观测卫星(Greenhouse gas Observing Satellite,GOSAT)搭载的被动红外探测器；③ ASCENDS和A|SCOPE等国际卫星计划正在研制中的星载主动激光雷达探测器。 进一步介绍了我国在高光谱仪器研制方面具备的研究基础。最后初步分析了星载CO2探测结果的验证、资料同化方法和未来的发展趋势。

| Abstract: | This paper summarize recent progresses in the technologies and methods of satellite|based instruments for atmospheric CO2 remote sensing, discuss the basic theory and retrieval method, and analyze the factors debasing the precision of CO2 measurement. Three kinds of instruments are discussed in detail:① Currently operating satellite instruments, which observe atmospheric CO2 and other components, such as Atmospheric Infrared Souner (AIRS), Scanning Imaging Absorption Spectrometer (SCIAMACHY) and Infrared Atmospheric Sounding Interferometer (IASI);② Specific instruments for detecting CO2 content in the lower troposphere, such as Orbiting Carbon Observatory (OCO) and Greenhouse gas Observing Satellite (GOSAT);③ Satellite projects focus on active instrument|laser lidar,such as Active Sensing of CO2 Emissions over Nights,Days,and Seasons (ASCENDS) and Advanced Space Carbon and Climate Observation of Planet Earth (A|SCOPE).In addition,we introduce technical basic in hyper spectral instrument in China.Validation,data assimilation and potential development of CO2 satellite remote sensing are discussed at the end of paper. |
