2019-2020年海上丝绸之路沿线1km Suomi/NPP VIIRS与Terra/Aqua MODIS港口城市PM2.5数据集

PM2.5是指近地表空气中空气动力学直径 ≤ 2.5 μm的颗粒物的总称，它由不同体积、形状、密度、表面积的粒子团混合而成。PM2.5对于人类健康、气候变化、生态环境等都有很重要的影响。该数据集由Suomi/NPP VIIRS与Terra/Aqua MODIS卫星遥感数据反演得到, 空间分辨率为1km，数据格式为tif。

PM2.5 refers to the collective term for particulate matter in near-surface air with an aerodynamic diameter ≤ 2.5 μm, which is composed of a mixture of particle clusters with varying volumes, shapes, densities and surface areas. PM2.5 exerts significant impacts on human health, climate change, ecological environment and other related fields. This dataset is retrieved from remote sensing data of Suomi/NPP VIIRS and Terra/Aqua MODIS satellites, with a spatial resolution of 1 km and a data format of .tif.
