摘　　要：欧空局2019年将“人为二氧化碳排放监测任务CO2M”列为哥白尼计划的Sentinel 7任务,并在前期方案设计的基础上,签订了载荷研制合同。该卫星的主要探测仪器有用于CO和NO探测的CO2I和NO2I组合光谱成像仪、多角度偏振仪MAP和三波段高空间分辨率云成像仪CLIM。基于公开文献,概述了该任务的需求以及主要光学有效载荷的性能指标需求、探测原理、结构设计和关键技术等。In 2019,the CO2 M mission has been selected by the ESA as Sentinel 7 in Copernicus programme,which will be measuring COconcentration in terms of column-averaged mole fraction(denoted as XCO).The payload comprises a suite of instruments addressing the various aspects of the challenging observation requirements.A push-broom imaging spectrometer will perform co-located measurements of top-of-atmosphere radiances in the near infrared(NIR)and short-wave infrared(SWIR)at high to moderate spectral resolution.A multi-angle polarimeter is co-located measurements of aerosols performed.Finally,measurements of a three-band cloud imager,co-registered with the COobservations,will provide the required cloud-flagging capacity at sub-sample level.This paper will review the results of the Phase A/B1 instrument studies,including technology pre-development activities,preliminary design of the CO2 M mission′s instruments,etc.
