MIX is a new anthropogenic emission inventory for Asia for the years 2008 and 2010. It is developed to support the Model Inter-Comparison Study for Asia Phase III (MICS-Asia III) and the Task Force on Hemispheric Transport of Air Pollution (TF HTAP) projects by a mosaic of up-to-date regional and national emission inventories including REAS inventory version 2.1 for the whole of Asia (Kurokawa et al., 2013), the Multi-resolution Emission Inventory for China (MEIC) developed by Tsinghua University, a high-resolution NH3 emission inventory by Peking University (Huang et al., 2012), an Indian emission inventory developed by Argonne National Laboratory (ANL-India, Lu et al., 2011; Lu and Streets, 2012), and the official Korean emission inventory from the Clean Air Policy Support System (CAPSS) (Lee et al., 2011). The development of the MIX inventory was led by Tsinghua University (Qiang Zhang) with input from Asia Center for Air Pollution Research (Jun-ichi Kurokawa and Toshimasa Ohara), Konkuk University (Jung-Hun Woo), Argonne National Laboratory (Zifeng Lu and David Streets), and Peking University (Yu Song).
MIX provided emission estimates for Asia for the years 2008 and 2010. The domain of MIX covers 30 countries and regions, stretching from Kazakhstan in the west to Far East Russia in the east, and from Indonesia in the south to Siberia in the north. Emissions are aggregated into five sectors: power, industry, residential, transportation, and agriculture. Ten chemical species are included in the MIX inventory, including both gaseous species and aerosol species: SO2, NOx, CO, NMVOC (non-methane volatile organic compounds), NH3 (ammonia), PM10 (particulate matter with diameter less than or equal to 10 μm), PM2.5 (particulate matter with diameter less than or equal to 2.5 μm), BC (black carbon), OC (organic carbon) and CO2. Only emissions from anthropogenic sources are included in MIX. NMVOC emissions are speciated into model-ready inputs for two chemical mechanisms: CB05 and SAPRC-99. Monthly emissions are provided by sector at 0.25º x 0.25º resolution.

- The MIX emission inventory is restricted to non-commercial purposes. Any uses of MIX by business organizations are regarded as commercial purpose which needs prior authorization.
- Users are not permitted to distribute the MIX data to any third-party.
- User must ensure the data integrity and independence when using MIX. Without explicit and prior authorization, no organization or individual is allowed to integrate any forms of the MIX data into other emission products or models.
- Papers, reports or products using the MIX data should cite the related publications of MIX.
Data version >
- June 2015, the MIX inventory was updated to version 1.1. Emissions of Hong Kong and the Republic of Korea, and NH3 emissions in China were updated.
- March 2013, MIX inventory v.1.0 was developed and submitted to MICS-Asia and HTAP projects.
