| Zusammenfassung |
| A new inventory of air pollutant emissions in Asia in the year 2006 is
developed to support the Intercontinental Chemical Transport
Experiment-Phase B (INTEX-B) funded by the National Aeronautics and Space
Administration (NASA). Emissions are estimated for all major anthropogenic
sources, excluding biomass burning. We estimate total Asian anthropogenic
emissions in the year 2006 as follows: 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. We emphasize emissions from China because they dominate
the Asia pollutant outflow to the Pacific and the increase of emissions from
China since 2000 is of great concern. We have implemented a series of
improved methodologies to gain a better understanding of emissions from
China, including a detailed technology-based approach, a dynamic methodology
representing rapid technology renewal, critical examination of energy
statistics, and a new scheme of NMVOC speciation for model-ready emissions.
We estimate China's anthropogenic emissions in the year 2006 to be as
follows: 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. We have
also estimated 2001 emissions for China using the same methodology and found
that all species show an increasing trend during 2001–2006: 36% increase
for SO2, 55% for NOx, 18% for CO, 29% for VOC, 13% for
PM10, and 14% for PM2.5, BC, and OC. Emissions are gridded at a
resolution of 30 min×30 min and can be accessed at our web site
