Improved DQ-1 spaceborne IPDA lidar XCO2 retrieval accuracy by an enhanced inversion and post-processing framework
Global climate change and the “Dual Carbon Strategy” have created an urgent demand for high- precision atmospheric carbon dioxide (CO₂) monitoring. In response, Atmospheric Carbon Dioxide Lidar (ACDL) onboard China’s Atmospheric Environment Monitoring Satellite (DQ-1) employs Integrated Path Differential Absorption (IP...
