ACDL monthly L3 1-degree gridded XCO2 products(202206-202305,v1.0)

This dataset provides the global monthly mean XCO₂ product retrieved from the Aerosol and Carbon Dioxide Lidar (ACDL) onboard the DQ-1 satellite, covering the period from June 2022 to May 2023. Detailed retrieval methods and data descriptions can be found in Han et al. (https://doi.org/10.1016/j.rse.2025.114954). ACDL is the world’s first spaceborne lidar for active detection of carbon dioxide and aerosols, and it is also the first satellite payload capable of observing XCO₂ in nighttime and high-latitude regions. The product is divided into daytime and nighttime observations and presented as monthly 1° × 1° gridded data. Each grid cell value represents the monthly mean of all total column XCO₂ observations within that cell (unit: ppm).
