Regional warming from aerosol removal over the United States: Results from a transient 2010–2050 climate simulation
(Elsevier BV, 2012)
We use a general circulation model (NASA Goddard Institute for Space Studies GCM 3) to investigate the regional climate response to removal of aerosols over the United States. We perform a pair of transient 2010–2050 climate ...
Impact of 2000–2050 Climate Change on Fine Particulate Matter (PM2.5) Air Quality Inferred from a Multi-Model Analysis of Meteorological Modes
(European Geosciences Union, 2012)
Studies of the effect of climate change on fine particulate matter (PM2.5) air quality using general circulation models (GCMs) show inconsistent results including in the sign of the effect. This reflects uncertainty in the ...
Impacts of Changes in Land Use and Land Cover on Atmospheric Chemistry and Air Quality over the 21st Century
(European Geosciences Union, 2012)
The effects of future land use and land cover change on the chemical composition of the atmosphere and air quality are largely unknown. To investigate the potential effects associated with future changes in vegetation ...
Climatic Effects of 1950-2050 Changes in US Anthropogenic Aerosols - Part 2: Climate Response
(European Geosciences Union, 2012)
We investigate the climate response to changing US anthropogenic aerosol sources over the 1950–2050 period by using the NASA GISS general circulation model (GCM) and comparing to observed US temperature trends. Time-dependent ...
Climatic Effects of 1950-2050 Changes in US Anthropogenic Aerosols - Part 1: Aerosol Trends and Radiative Forcing
(European Geosciences Union, 2012)
We calculate decadal aerosol direct and indirect (warm cloud) radiative forcings from US anthropogenic sources over the 1950–2050 period. Past and future aerosol distributions are constructed using GEOS-Chem and historical ...
Tropospheric Bromine Chemistry: Implications for Present and Pre-Industrial Ozone and Mercury
(European Geosciences Union, 2012)
We present a new model for the global tropospheric chemistry of inorganic bromine (Bry) coupled to oxidant-aerosol chemistry in the GEOS-Chem chemical transport model (CTM). Sources of tropospheric Bry include debromination ...
Correlations between Fine Particulate Matter \((PM_{2.5})\) and Meteorological Variables in the United States: Implications for the Sensitivity of \(PM_{2.5}\) to Climate Change
(Elsevier, 2010)
We applied a multiple linear regression (MLR) model to study the correlations of total \(PM_{2.5}\) and its components with meteorological variables using an 11-year (1998–2008) observational record over the contiguous US. ...
Meteorological Modes of Variability for Fine Particulate Matter (PM2.5) Air Quality in the United States: Implications for PM2.5 Sensitivity to Climate Change
(European Geosciences Union, 2012)
We applied a multiple linear regression model to understand the relationships of PM2.5 with meteorological variables in the contiguous US and from there to infer the sensitivity of PM2.5 to climate change. We used 2004–2008 ...
Effects of 2000-2050 Global Change on Ozone Air Quality in the United States
(American Geophysical Union, 2008)
We investigate the effects on U.S. ozone air quality from 2000–2050 global changes in climate and anthropogenic emissions of ozone precursors by using a global chemical transport model (GEOS-Chem) driven by meteorological ...
Effect of Changes in Climate and Emissions on Future Sulfate-Nitrate-Ammonium Aerosol Levels in the United States
(American Geophysical Union, 2009)
Global simulations of sulfate, nitrate, and ammonium aerosols are performed for the present day and 2050 using the chemical transport model GEOS-Chem. Changes in climate and emissions projected by the IPCC A1B scenario are ...
