2050年中国典型区域大气环境容量分区数据集

数据集包含基于NAQPMS空气质量模式模拟结果，计算得到的2050年全国大气自净容量、容载量和容量余量。数据集给出的容量数据目标地区为全国各个城市，目标PM2.5浓度为日均75μg/m3，时间分辨率为每天。大气自净容量、容载量和容量余量分别对应大气清除能力、PM2.5浓度累计能力和大气超载量。This dataset contains three metrics, namely atmospheric self-purification capacity, pollutant carrying capacity and capacity margin, for China in 2050, which are calculated based on the simulation results of the NAQPMS air quality model. The target regions covered by the capacity data in this dataset are all cities across China, with the target daily average PM2.5 concentration of 75 μg/m³ and a daily temporal resolution. Specifically, atmospheric self-purification capacity, pollutant carrying capacity and capacity margin respectively correspond to atmospheric removal capacity, cumulative carrying capacity for PM2.5 concentration and atmospheric overload.
