Overview >

MIXv2 is a mosaic emission inventory for Asia for the years 2010-2017, which is an updated version of MIXv1. It is developed to support the Model Inter-Comparison Study for Asia Phase IV (MICS-Asia IV) project by a mosaic of up-to-date regional and national emission inventories, including REAS v3 for Asia (Asia Center for Air Pollution Research/National Institute for Environmental Studies), MEIC for China (Tsinghua University), high-resolution NH₃ and open biomass burning emission inventories for China (Peking University), an Indian power plant emission inventory (Argonne National Laboratory), national emission inventories for Japan (MOE-J and J-STREAM), the official Korean emission inventory from the Clean Air Policy Support System (CAPSS) for the Republic of Korea (provided by Konkuk University), and global emissions from GFED v4 for open biomass burning and EDGAR v6 for shipping.

MIXv2 provided anthropogenic and open biomass burning sources emission estimates for Asia for the years 2010-2017. The domain of MIXv2 covers 23 Asian countries and regions. Emissions are aggregated into seven sectors: power, industry, residential, transportation, agriculture, open_biomass and shipping. Ten chemical species are included, including both gaseous species and aerosol species: SO₂, NO_x, CO, NMVOC (non-methane volatile organic compounds), NH₃ (ammonia), PM₁₀ (particulate matter with diameter less than or equal to 10 μm), PM_2.5 (particulate matter with diameter less than or equal to 2.5 μm), BC (black carbon), OC (organic carbon) and CO₂. NMVOC emissions are speciated into model-ready inputs for three chemical mechanisms: CB05, SAPRC-99 and SAPRC-07. Monthly emissions are provided by sectors at a 0.1º× 0.1º resolution. Comparing with MIX v1, MIXv2 has a longer time coverage and has been updated until 2017. In addition, it has added emission from two sectors: Open_biomass and Shipping, and monthly emissions are provided by sectors at a higher resolution (0.25 degree for MIX v1). It has added SAPRC-07 chemical mechanism for NMVOC.
