Data from satellite sensors such as the MODerate Resolution Imaging Spectroradiometer (MODIS) and ground based in-situ measurements have been analyzed to determine the transport and impact of pollutants to Class I areas. The combination of surface monitors from networks such as Interagency Monitoring for PROtected Visual Environments (IMPROVE) with time series and transport model analysis has been effective in determining sources of haze to Class I areas. We have demonstrated that MODIS can be used to monitor aerosol transport using spaceborne observations.1 In this study, we present an initial examination of transport of pollutants to a number of Class I sites. Products such as Aerosol Optical Depth (AOD), and ground based in-situ measurements such as Particulate Matter (PM) and visibility are examined. We expect that analysis of MODIS data will lead to significant advances in the ability to discern sources of aerosol to these sensitive areas. In the future, we aim to develop an integrated empirical/observational model that addresses air pollutant transport to protected ecosystems.
