to calculate the domestic and foreign contributions to air quality and related premature mortality. Total premature mortality was estimated to be 414 000 in Europe and
160 000 in the U.S., using multi-model mean pollutant concentrations. The number
of premature mortality cases calculated using concentration inputs from different air
quality models can vary by up to a factor of three. Results show that the domestic
emissions have the largest impacts on premature death, while foreign sources are a
minor contributor to adverse impacts of air pollution.
73.1 Introduction
According to the World Health Organization (WHO), air pollution is now the world’s
largest single environmental health risk. Chemistry and transport models (CTMs) are
useful tools to calculate the concentrations of health-related pollutants taking into
account the non-linearities in the chemistry and the complex interactions between
meteorology and chemistry. However, CTMs include different chemical and aerosol
schemes that introduce differences in the representation of the processes. These
uncertainties are introduced into the health impact estimates using output from these
different CTMs. Multi-model (MM) ensembles can be useful to minimize these
uncertainties introduced by the individual CTMs.
The AQMEII project attempts to bring together modellers from both sides of the
Atlantic Ocean to perform joint regional model experiments using common boundary conditions, and emissions with a specific focus on regional modelling domains
over Europe and North America [3]. AQMEII Phase 3 (AQMEII3) is devoted to
performing joint modelling experiments with HTAP2.
