A new inventory of air pollutant emissions in Asia in the year 2006 is developed to support the Intercon-tinental 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(More)
[1] An inventory of air pollutant emissions in Asia in the year 2000 is developed to support atmospheric modeling and analysis of observations taken during the TRACE-P experiment funded by the National Aeronautics and Space Administration (NASA) and the ACE-Asia experiment funded by the National Science Foundation (NSF) and the National Oceanic and(More)
A survey of biomass burning in Asia is developed to assist in the modeling of Asian and global air quality. A survey of national, regional, and international publications on biomass burning is conducted to yield consensus estimates of " typical " (i.e., non-year-specific) estimates of open burning (excluding biofuels). We conclude that 730 Tg of biomass are(More)
17 18 A comprehensive regional-scale chemical transport model, STEM-2K1, is employed to study dust 19 outflows and their influence on regional chemistry in the high dust ACE-ASIA period, from April 4 to 14, 20 2001. In this period, dust storms are initialized in the Taklamagan and Gobi deserts due to cold air 21 outbreaks, are transported eastward, and(More)
[1] Understanding the surface O 3 response over a ''receptor'' region to emission changes over a foreign ''source'' region is key to evaluating the potential gains from an international approach to abate ozone (O 3) pollution. We apply an ensemble of 21 global and hemispheric chemical transport models to estimate the spatial average surface O 3 response(More)
[1] Data obtained during the TRACE-P experiment is used to evaluate how well the CFORS/STEM-2K1 regional-scale chemical transport model is able to represent the aircraft observations. Thirty-one calculated trace gas and aerosol parameters are presented and compared to the in situ data. The regional model is shown to accurately predict many of the important(More)
[1] The Chemical Weather Forecast System (CFORS) is designed to aid in the design of field experiments and in the interpretation/postanalysis of observed data. The system integrates a regional chemical transport model with a multitracer, online system built within the Regional Atmospheric Modeling System (RAMS) mesoscale model. CFORS was deployed in(More)
[1] In this paper, aerosol composition and size distributions in east Asia are simulated using a comprehensive chemical transport model. Three-dimensional aerosol simulations for the TRACE-P and ACE-Asia periods are performed and used to help interpret actual observations. The regional chemical transport model, STEM-2K3, which includes the on-line(More)
[1] Vertical profiles of aerosol size, composition, and hygroscopic behavior from Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) Twin Otter and National Oceanic and Atmospheric Administration R/V Ronald H. Brown observations are used to construct a generic optical model of the Asian Pacific Regional Aerosol Characterization(More)
In the numerical simulation of atmospheric transport-chemistry processes, a major task is the integration of the stii systems of ordinary diierential equations describing the chemical transformations. It is therefore of interest to systematically search for stii solvers which can be identiied as close to optimal for atmospheric applications. In this paper(More)
