INTAC: a high-resolution INTegrated emission inventory of Air pollutants for China in 2017

Description

A 0.1° resolution air pollutant emission inventory for China in 2017 is constructed by harmonizing multisource emission datasets including seven up-to-date emission inventories at national and regional scale, and for key species and sources.  We develop an integrated modeling framework to normalize different datasets in terms of source categories, chemical species, and spatiotemporal resolutions by source mapping, species mapping, temporal disaggregation, spatial allocation and spatial-temporal coupling. This achieves the coupling of multi-scale, high-resolution emission inventories with the MEIC (Multi-resolution Emission Inventory for China), forming a high-resolution INTegrated emission inventory of Air pollutants for China (i.e., INTAC).

This inventory includes China's gridded air pollutant emissions for 2017 by species, sector, month.

  • Species: SO2, NOx, CO, NMVOC, NH3, PM10, PM2.5, BC, OC
  • Sectors: power, industry, residential, transportation, agriculture, solvent use, shipping, open biomass burning
  • Temporal information: 2017; monthly
  • Spatial information: 70E-150E, 10N-60N; 0.1°
