<abstract>
<p>A comprehensive numerical modeling framework was developed to estimate the
effects of collective global changes upon ozone pollution in the US in
2050. The framework consists of the global climate and chemistry models, PCM
(Parallel Climate Model) and MOZART-2 (Model for Ozone and Related Chemical
Tracers v.2), coupled with regional meteorology and chemistry models, MM5
(Mesoscale Meteorological model) and CMAQ (Community Multi-scale Air Quality
model). The modeling system was applied for two 10-year simulations:
1990–1999 as a present-day base case and 2045–2054 as a future case. The
regional simulations employed 36-km grid cells covering the continental US
with boundary conditions taken from the global models. For the current
decade, the distributions of summer daily maxima 8-h (DM8H) ozone showed
good agreement with observed distributions throughout the US. The future
case simulation followed the Intergovernmental Panel on Climate Change
(IPCC) A2 scenario together with business-as-usual US emission projections
and projected alterations in land use, land cover (LULC) due to urban
expansion and changes in vegetation. For these projections, US
anthropogenic NO&lt;sub&gt;x&lt;/sub&gt; (NO + NO&lt;sub&gt;2&lt;/sub&gt;) and VOC (volatile organic carbon)
emissions increased by approximately 8% and 50%, respectively, while
biogenic VOC emissions decreased, in spite of warmer temperatures, due to
decreases in forested lands and expansion of croplands, grasslands and urban
areas. A stochastic model for wildfire emissions was applied that projected
25% higher VOC emissions in the future. For the global and US emission
projection used here, regional ozone pollution becomes worse in the
2045&amp;ndash;2054 period for all months. Annually, the mean DM8H ozone was projected
to increase by 9.6 ppbv (22%). The changes were higher in the spring and
winter (25%) and smaller in the summer (17%). The area affected by
elevated ozone within the US continent was projected to increase; areas
with levels exceeding the 75 ppbv ozone standard at least once a year
increased by 38%. In addition, the length of the ozone season was
projected to increase with more pollution episodes in the spring and fall.
For selected urban areas, the system projected a higher number of pollution
events per year and these events had more consecutive days when DM8H ozone
exceed 75 ppbv.</p>
