ABSTRACT Using satellite observations of aerosol optical depth (AOD) to estimate surface concentrations of fine particulate matter ([PM.sub.2.5]) is a well-established technique in the air quality community. In this study, the relationships between [PM.sub.2.5] concentrations measured at five monitor locations in the Baltimore, MD/Washington, DC region and AOD from Moderate Resolution Imaging Spectroradiometer (MODIS), Multi-Angle Imaging Spectroradiometer (MISR), and Geostationary Operational Environmental Satellite (GOES) were calculated for the summer of 2004 and all of 2005. Linear regression methods were used to determine the direct quantitative relationships between the satellite AOD values and [PM.sub.2.5] concentration measurements. Results show that correlations between AOD and surface [PM.sub.2.5] concentrations range...
