星载二氧化碳探测研究进展

Progress of Spaceborne CO_(2) Measurement

二氧化碳(CO_(2))是大气中最典型的温室气体,大气中CO_(2)浓度持续增加是全球气温升高的主要原因。温度升高导致自然环境恶劣,各类自然灾害频发,极端天气数量增加,对人类生活环境造成巨大的影响,因此推动绿色低碳发展势在必行。准确监测CO_(2)的排放,了解CO_(2)源和汇的分布,是遏制大气CO_(2)浓度升高、减缓全球变暖的前提条件。因此,准确获取全球范围内高精度时空分辨率的CO_(2)观测数据十分必要。卫星遥感可以有效观测CO_(2)的全球分布,获取大范围高精度数据。本文旨在对目前用于大气CO_(2)探测的卫星载荷发展状况进行综述,包括基于被动遥感CO_(2)的卫星现状和数据产品、基于主动遥感CO_(2)的卫星的研制情况和目前的主要工作进展。

CO_(2) is the most typical greenhouse gas in the atmosphere.The continuous increase in the CO_(2) concentration in the atmosphere is the main reason for global warming.The increasing temperature has led to the deterioration of the natural environment,the frequent occurrences of various natural disasters,and the increase in the number of extreme weathers,which have a huge impact on the living environment of human beings.Therefore,it is imperative to promote green and low-carbon development.Accurately monitoring atmospheric CO_(2) emissions and understanding the distribution of carbon dioxide sources and sinks are essential prerequisites for curbing the increase in the CO_(2) concentration and climate change.Thus,it is necessary to accurately obtain the observational data of CO_(2) with high spatial and temporal resolution around the world.Satellite remote sensing can realize effective observation of the global distribution of CO_(2) and obtain large-scale high-precision data.This paper aims to summarize the current status of satellites mainly used for CO_(2) detection,including the status and data products of satellites based on passive remote sensing of CO_(2),as well as the development and current main work progress of satellites based on active remote sensing of CO_(2).
