A new inventory of air pollutant emissions in Asia for 2006 was developed to support the Intercontinental Chemical Transport Experiment-Phase B (INTEX-B) mission funded by NASA. The inventory includes emissions from all major anthropogenic sources, excluding biomass burning. Total Asian anthropogenic emissions in 2006 are estimated as 47.1 Tg SO₂, 36.7 Tg NOₓ, 298.2 Tg CO, 54.6 Tg NMVOC, 29.2 Tg PM₁₀, 22.2 Tg PM₂.₅, 2.97 Tg BC, and 6.57 Tg OC. China's emissions are emphasized as they dominate Asian pollutant outflow to the Pacific. China's 2006 emissions are estimated as 31.0 Tg SO₂, 20.8 Tg NOₓ, 166.9 Tg CO, 23.2 Tg NMVOC, 18.2 Tg PM₁₀, 13.3 Tg PM₂.₅, 1.8 Tg BC, and 3.2 Tg OC. Emissions for 2001 using the same methodology show an increase in all species from 2001–2006. Emissions are gridded at 30 min × 30 min resolution and available at the website (http://mic.greenresource.cn/intex-b2006). The INTEX-B inventory covers 22 Asian countries and regions, from Pakistan to Japan and Indonesia to Mongolia. The inventory includes eight major chemical species: SO₂, NOₓ, CO, NMVOC, PM₁₀, PM₂.₅, BC, and OC. Methane (CH₄) and ammonia (NH₃) were not updated as they have not changed much since 2000. NMVOC emissions are speciated into five categories corresponding to five chemical mechanisms. Only anthropogenic emissions are estimated, with biomass burning emissions included in the TRACE-P inventory but replaced by more accurate high-resolution inventories. The methodology used includes a detailed technology-based approach, dynamic methodology for rapid technology renewal, critical examination of energy statistics, and a new NMVOC speciation scheme. Emissions are calculated by country and by province for China, with seasonal variations considered for some species. Monthly emissions are developed using various methods, and spatial distributions are provided at 30 min × 30 min resolution. All data can be downloaded from the website. The inventory shows significant increases in emissions from 2001–2006, with SO₂, NOₓ, CO, VOC, PM₁₀, and PM₂.₅ increasing by 36%, 55A new inventory of air pollutant emissions in Asia for 2006 was developed to support the Intercontinental Chemical Transport Experiment-Phase B (INTEX-B) mission funded by NASA.
