资源简介:
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,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NO2数据。主要范围为整个中国地区,时间分辨率为年,单位为µg/m3。
This dataset employs artificial intelligence (AI) techniques, takes into account the spatiotemporal heterogeneity of air pollution, and generates spatially seamless ground-level NO₂ concentration data across mainland China. It is derived from multi-source big data including ground-based observations, satellite remote sensing products, atmospheric reanalysis data, model simulation outputs and other relevant datasets. The dataset covers the entire Chinese mainland, with an annual temporal resolution and units of µg/m³.
