Progress and Case Study of Satellite Remote Rensing Technology for Carbon Dioxide

As the primary cause of global warming, the increase in atmospheric carbon dioxide(CO2) concentration has attracted more and more attention worldwide. With the slogan of “peaking carbon” and “carbon neutrality” in China, the need for quantitative, real-time, and large-scale monitoring of CO2 concentration is becoming more urgent. As an all-weather, high-precision monitoring method for greenhouse gas emissions, satellite remote sensing has great potential in CO2 monitoring. After studying the development and performance of remote sensing satellites for CO2 monitoring, the conclusion drawn by this paper is that the monitoring accuracy of CO2 monitoring sensors is gradually improved with increasing attention to CO2 concentration detection in various countries and that because active remote sensing is not affected by aerosol and solar radiation, the current high-precision CO2 concentration detection has gradually changed from passive remote sensing to a combination of active and passive remote sensing. By reviewing the development process of CO2 monitoring remote sensing satellites and the research and application of CO2 satellite data, this paper finds out the gaps in the current research of CO2 remote sensing satellites. It inspires future scholars who want to carry out research in this field.
