Impact/Purpose:
The predictive surfaces are intended for use by statisticians and environmental scientists interested in the spatial distribution of pollution over daily time periods over 2001-2005. These surfaces could be used in modeling public health – air quality relationships, modeling ecosystem reactions to atmospheric inputs, and determining geographic areas with high pollution levels exceeding threshold levels. As new space-time models are developed, we will evaluate their use for providing improved predictions of air and deposition variables.
Description:
A space-time Bayesian fusion model (McMillan, Holland, Morara, and Feng, 2009) is used to provide daily, gridded predictive PM2.5 (daily average) and O3 (daily 8-hr maximum) surfaces for 2001-2005. The fusion model uses both air quality monitoring data from the National Air Monitoring Stations/State and Local Air Monitoring Stations (NAMS/SLAMS) and numerical output from the Models-3/Community Multiscale Air Quality (CMAQ). Predictive surfaces are provided over the entire CMAQ 12 km and 36 km spatial domains for each year.
