Thurston, and Richard T. Burnett Satellite instruments offer researchers powerful new perspectives and data sources for studying the environment. A new study used associations between fine particulate matter (PM2.5) and mortality from circulatory diseases as a test scenario to explore how exposure estimates derived from remote sensing alone compare with those produced by a combination of satellite- and ground-based data.1 The findings showed associations between PM2.5 and mortality regardless of the method used, but specific relative risk estimates varied widely, with hybrid models generally predicting t...
