中国二氧化碳浓度公里网格遥感数据集

中国二氧化碳（CO2）浓度公里网格遥感数据集为全国范围的2015-2021年的CO2浓度空间分布公里网格数据。该数据集可以从国家、省级行政区、市级行政区、城市群等不同尺度、全面揭示中国CO2浓度的时空分布特征，有利于全面了解同一行政单元内、不同行政单元间CO2浓度的区域变化及差异特征。同时数据集支持以重点区域的方式开展区域CO2浓度变化研究，能够为我国重点区域的大气环境质量管理和规划提供政策指导，为国家碳监测和碳减排提供科学数据基础。

The China Kilometer-scale Gridded Remote Sensing Dataset of Carbon Dioxide (CO2) Concentration provides kilometer-resolution gridded data on the spatial distribution of CO2 concentrations nationwide for the period 2015–2021. This dataset comprehensively reveals the spatiotemporal distribution characteristics of China’s CO2 concentrations at multiple scales, including national, provincial, municipal, and urban agglomeration levels, and facilitates a thorough understanding of regional variations and differences in CO2 concentrations both within individual administrative units and among different administrative units. Furthermore, the dataset supports research on regional CO2 concentration changes by focusing on key areas. It can provide policy guidance for atmospheric environmental quality management and planning of China’s key regions, and serve as a scientific data foundation for national carbon monitoring and carbon emission reduction.
