【摘要】 气候问题已经成为人类需要采取紧急措施共同面对的一大挑战，温室气体的全球测量对于监测气候状况、了解排放变化等至关重要。激光雷达技术发展日趋成熟，在全球温室气体探测领域展现出巨大潜力。本文首先介绍了主动遥感在温室气体探测方面的优势，随后对当前国内外主要的星载温室气体探测激光雷达ASCENDS、A-SCOPE、MERLIN以及相关的方案进行了总结。最后介绍了国际上首个可以昼夜工作的星载激光雷达温室气体测量系统ACDL及其数据结果，并对未来的星载激光雷达在温室气体测量领域的发展进行了展望。更多还原

【Abstract】 Climate change has become a major challenge which requires urgent action from humanity to address collectively. Global measurement of greenhouse gases is crucial for monitoring climate conditions and understanding emission changes. Lidar technology is getting mature and shows great potential in the field of global greenhouse gas detection. This article introduces the advantages of active remote sensing in greenhouse gas detection, and then summarizes the current major spaceborne greenhouse gas detection lidar programs, including ASCENDS, A-SCOPE, MERLIN, and related programs. After that, the data results of the first international spaceborne lidar system, ACDL were presented. ACDL is capable of working day and night to measure greenhouse gases concentration. Finally, an outlook on the future development of spaceborne lidar system for greenhouse gas measurements was provided.更多还原
