中国1km高分辨率高质量逐日近地表CO数据集(2019-2024年)

该数据集利用人工智能技术，考虑了空气污染的时空异质特性，使用人工智能从大数据(如地基观测、卫星遥感产品、大气再分析和模式模拟资料等)中生产得到全国无缝隙地面CO数据。主要范围为整个中国地区，时间分辨率为日，单位为mg/m3。This dataset adopts artificial intelligence technologies, taking into account the spatiotemporal heterogeneity of air pollution. It generates nationwide seamless near-surface CO concentration data by processing large-scale datasets including ground-based observations, satellite remote sensing products, atmospheric reanalysis data, and model simulation outputs. The dataset covers the entire Chinese mainland, with a daily temporal resolution, and the unit is mg/m³.
