中国1km分辨率逐日无缝气溶胶细粒子比FMF数据集(2000年-2020年)

该数据集为我国首套长时序高分辨率时空无缝气溶胶细粒子比FMF数据产品。时间分辨率为逐日，时间覆盖范围为2000~2020年；空间分辨率为1km，经度范围为71°E~139°E，纬度范围为15°N ~56°N。产品验证精度达0.80以上，可为揭示我国大气灰霾污染的长期变化规律及空间分异特征、大气污染健康风险估算与气溶胶辐射效应等研究提供重要的数据支持。

This dataset is China's first long-term time-series high-resolution spatiotemporally seamless fine mode fraction (FMF) data product of aerosols. It has a daily temporal resolution, with a temporal coverage spanning from 2000 to 2020, and a spatial resolution of 1 km, covering a longitudinal range of 71°E to 139°E and a latitudinal range of 15°N to 56°N. The validation accuracy of this product exceeds 0.80, providing essential data support for studies on revealing the long-term variation patterns and spatial differentiation characteristics of atmospheric haze pollution in China, as well as health risk assessment of air pollution and radiative effects of aerosols.
