全球温室气体卫星遥感观测



   温室气体卫星遥感观测技术已成为重要的大气浓度数据获取手段之一;其时间连续以及全球覆盖的观测技术有望改进全球大气单点观测(GAW)的局限性以及模型模拟的不确定性,以揭示温室气体浓度的时空变化规律以及全球和区域碳源与碳汇的分布。

   At present,we still do not clearly understand the spatial distribution of global greenhouse gases concentrations such as carborn dioxide(CO2)and methane(CH4),and their temporal variations because there are no large-scale global observing data available.The Greenhouse Gases Observing SATellite(GOSAT)is designed for monitoring the global distribution of CO2 and CH4 from orbit.We are using GOSAT data to investigate and assess the spatial and temporal variations of global and regional greenhouse gases,and carborn sink and source.
