摘要
为了深入了解国际上新一代CO2等温室气体的空间观测计划及进展情况,以日本和美国于2009年最新发射的温室气体测卫星"呼吸"号(GOSAT)、"轨道碳观测者"(OCO)为例,分析了观测计划的开展情况,对卫星上搭载的传感器设置做了分析,对新一代温室气体专用观测卫星与传统卫星上的传感器做了对比,得出了新一代的传感器在设置上的特点:波段设置在近红外太阳辐射以获得边界层的温室气体含量,具有高的光谱分辨率以保证观测精度,多种观测方式结合以获得最大的信息量。并提出了我国应对温室气体观测资料缺乏的对策,发展专用观测卫星或传感器,以提供我们自己的高精度的全球和区域温室气体观测数据。
Several instruments on the new-generation greenhouse gases observing satellites are discussed and reviewed,especially GOSAT（Greenhouse Gases Observing Satellite） and OCO（Orbiting Carbon Observatory）,which were launched by NASA and JAXA,in order to follow the advances in the field of greenhouse gases observation in the world.Taking GOSAT and OCO as examples,the configuration setting of the sensors onboarded is analyzed.By contrasting and analyzing the sensors onboarded in new generation satellites and traditional ones,some suggestions are given on the condition of lacking greenhouse gases observing data.
