Overview >

The China High-Resolution Air Pollutant Integrated Inventory is a national 10-kilometer-resolution emission inventory of 2017 developed by the MEIC team and some scientific research institutions with the support of the National Natural Science Foundation of China and related projects. Based on the comparison, uncertainty analysis and comprehensive evaluation of existing emission inventories, the research team used the MEIC model to integrate all the advantageous parts and improve the methods and parameters of MEIC model. Through emission source mapping, chemical species mapping, spatial grid matching, and time scale unification, the research team the normalized emission source, species, and spatial-temporal resolution, realizing the coupling of multi-scale and high-resolution emission inventories with MEIC national emission inventory. The missing information of emission sources in MEIC inventory (open burning of biomass, etc.) has been well supplemented, and a set of China’s multi-scale and high-resolution air pollutant emission inventory has been formed.

The China High-Resolution Air Pollutant Integrated Inventory was coupled with the Yangtze River Delta (YRD) Air Pollutant Emission Inventory developed by Zhao Yu’s research group of Nanjing University, the GBA-EI developed by Zheng Junyu’s research group of Jinan University, the High-resolution Ammonia Emission Inventory in China (PKU-NH3) and the Open Biomass Burning Emission Inventory in China developed by Song Yu’s research group of Peking University, the BJUT-OBB (Open biomass burning) emission inventory developed by Ying Zhou’s research group of Beijing University of Technology, and Shipping Emission Inventory in East Asia developed by Liu Huan’s research group of Tsinghua University. The spatial resolution of the 2017 national emission inventory data product is 0.1 degrees (about 10 kilometers) and the temporal resolution is months, including nine major air pollutants such as SO2, NOx, CO, NMVOC, NH3, PM10, PM2.5, BC and OC. The spatial resolution of the 2017 national emission inventory data product is 0.1 degrees (about 10 kilometers) and the temporal resolution is months, including nine major air pollutants such as SO₂、NO_x、CO、NMVOC、NH₃、PM₁₀、PM_2.5、BC、OC.
