Impact/Purpose:
The National Exposure Research Laboratory’s Atmospheric Modeling Division (AMAD) conducts research in support of EPA’s mission to protect human health and the environment. AMAD’s research program is engaged in developing and evaluating predictive atmospheric models on all spatial and temporal scales for forecasting the Nation’s air quality and for assessing changes in air quality and air pollutant exposures, as affected by changes in ecosystem management and regulatory decisions. AMAD is responsible for providing a sound scientific and technical basis for regulatory policies based on air quality models to improve ambient air quality. The models developed by AMAD are being used by EPA, NOAA, and the air pollution community in understanding and forecasting not only the magnitude of the air pollution problem, but also in developing emission control policies and regulations for air quality improvements.
Description:
This paper highlights the development of the emission inventories and emission processing for Europe (EU) and North America (NA) in the second phase of the Air Quality Model Evaluation International Initiative (AQMEII) project. The main purpose of the second phase of the AQMEII project is to understand the importance of coupled meteorological-chemical models in our understanding of the feedback of chemistry on the meteorology. A second purpose of the second phase of the AQMEII project is to explore the differences between EU and NA in a dynamic evaluation of two modeling years (2006 and 2010). For the EU domain, there was substantial decrease in CO (-19%), NH3 (-11%), and SO2 (-12%) emissions between phase 2 and phase 1 emissions for 2006. For the NA domain, there were decreases in CO (-10%), non-methane hydrocarbons (-5%), PM2.5 (-8%), PM10> (-18%), SO2 (-12%), with an increase of 4% in NOx. Between 2006 and 2009, considerable emission reductions were achieved for 17 EU countries, Norway and Switzerland as well as EU-Non-Member States, for all emissions classes aside from NH3, which increased. Non-EU countries showed little change in emissions levels, though this may be a result of poor data quality. Shipping emissions decreased for PM and SO2 due to Sulfur Emission Control Areas on the North Sea and the Baltic Sea, while increasing for other species. Between 2006 and 2010, estimated US NOx emissions decreased by 17%, SO2 by 29%, CO by 21%, PM2.5 by 12%, PM10 by 7%, NMHC by 4% and NH3 by 2%. Between 2006 and 2010, biogenic emissions in North America increased in the east and decreased in the west, due to regional temperature differences between the years. The European emissions of isoprene peaked earlier in 2006, but achieved higher levels in 2010.
