Application Progress of Remote Sensing Technology in the Realization of “Double Carbon” Goal

在全球努力实现碳中和目标的背景下中国也提出了“30-60”双碳目标。遥感技术有着地域范围广、追溯时期长的特点,因此,遥感可以快速、连续地获得全球碳源/汇空间分布和变化特性,可以在碳汇估算和管理、全球碳排放监测以及方面有着广阔的应用。文章首先综合阐述了陆地碳循环的模式,遥感技术在“双碳”目标实现中可以应用的领域、包括温室气体监测、碳排放源监测、陆地碳循环、遥感定量计算碳通量等。对关键概念进行了解释。然后,分析了遥感技术在遥感定量计算不同碳通量中使用到的方法和研究进展,同时提出了遥感监测碳排放和定量估算碳通量中可能存在的问题。

In the context of global efforts to achieve carbon neutrality, China has also proposed a "30-60" dual carbon target. Remote sensing technology has the characteristics of large scale coverage and a long time-series. Therefore, remote sensing can quickly and continuously obtain the characteristics of global spatial distribution and change, and has a broad application in the estimation and management of carbon sinks. In this paper, terrestrial carbon cycle is introduced and the key concepts are explained. Then, the methods and research progress of remote sensing technology used in remote sensing quantitative calculation of different carbon fluxes are analyzed. At the same time, the possible problems in remote sensing monitoring carbon emission and quantitative estimation of carbon flux are also put forward.
