Characterizing the photochemical sensitivity to emissions and local meteorology of 2 South American megacities : Bogotá, Santiago and the effect of local lockdowns

This dataset contains urban vehicle exhaust emission of NO2 and MP2.5 from on-road transportation in Santiago, Chile, for the period March-June 2020; and PM10 exhaust emissions at Bogota, Colombia, for March-April 2020. The data is presented as NetCDF4 files, in Gg/y per cell for each specie and at different hours, gridded with a spatial resolution of 0.01° x 0.01°. Santiago includes three periods: 7, 12 and 19 hours, and Bogota comprises the periods: 5, 12 and 21 hours.

本数据集收录了智利圣地亚哥市在2020年3月至6月期间，道路上交通工具排放的二氧化氮（NO2）和PM2.5颗粒物浓度，以及哥伦比亚波哥大市在2020年3月至4月期间的PM10颗粒物排放数据。数据以NetCDF4格式呈现，以每格网单元年排放量（Gg/y）为单位，针对每种污染物和不同时段进行网格化处理，空间分辨率为0.01° x 0.01°。圣地亚哥市数据分为7小时、12小时和19小时三个时段，而波哥大市数据则包括5小时、12小时和21小时三个时段。
