Constructing maps of dry deposition pollution levels is vital for air quality management, and presents statistical problems typical of many environmental and spatial applications. Ideally, such maps would be based on a dense network of monitoring stations, but this does not exist. Instead, there are two main sources of information for dry deposition levels(More)
There is a growing interest in quantifying the health impacts of climate change. This paper examines the risks of future ozone levels on non-accidental mortality across 19 urban communities in Southeastern United States. We present a modeling framework that integrates data from climate model outputs, historical meteorology and ozone observations, and a(More)
Tropospheric ozone is one of the six criteria pollutants regulated by the United States Environmental Protection Agency under the Clean Air Act and has been linked with several adverse health effects, including mortality. Due to the strong dependence on weather conditions, ozone may be sensitive to climate change and there is great interest in studying the(More)
Particulate matter (PM) has been associated with mortality in several epidemiological studies. The US EPA currently regulates PM(10) and PM(2.5) (mass concentration of particles with diameter less than 10 microm and 2.5 microm, respectively), but it is not clear which size of particles are most responsible for adverse heath outcomes. A current hypothesis is(More)
BACKGROUND Epidemiologic literature suggests that exposure to air pollutants is associated with fetal development. OBJECTIVES We investigated maternal exposures to air pollutants during weeks 2-8 of pregnancy and their associations with congenital heart defects. METHODS Mothers from the National Birth Defects Prevention Study, a nine-state case-control(More)
Estimating the probability of extreme temperature events is difficult because of limited records across time and the need to extrapolate the distributions of these events, as opposed to just the mean, to locations where observations are not available. Another related issue is the need to characterize the uncertainty in the estimated probability of extreme(More)
Storm surge is the onshore rush of seawater associated with hurricane force winds and can lead to loss of property and loss of life. Currently storm surge estimates are created by numerical ocean models that use a deterministic formula for surface wind fields. A new multivariate spatial statistical framework is developed to improve the estimation of these(More)
