In contrast to the passive remote sensing of global CO 2 column concentrations (XCO ), active with a lidar enables continuous XCO measurements throughout entire atmosphere in daytime and nighttime. The could penetrate most cirrus is almost unaffected by aerosols. Atmospheric environment monitoring satellite (AEMS, also named DQ-1) aerosol carbon dioxide detection Lidar (ACDL) novel spaceborne that implements 1572 nm integrated path differential absorption (IPDA) method measure for first time. this study, special methods have been developed ACDL data processing retrieval. measurement products ACDL, including optical depth between online offline wavelengths, integral weighting function, , are presented. results over period from 1 st June 2022 30 th (first month ACDL) analyzed demonstrate capabilities system.
