Recently developed analysis methods have enabled high-resolution mapping and emissions estimates from localized sources using data from the current generation of space-based air quality sensors. In this work, measurements from the SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY), GOME2 (Global Ozone Monitoring Experiment 2), and OMI (Ozone Monitoring Instrument) satellite instruments have been used to estimate emissions of NOx and SO2 from localized, near-point sources including urban areas, industrial locations (power plants, smelters, oil-related facilities), and volcanoes. Methods, error analyses, and results from several case studies, including the Canadian oil sands, will be presented. The benefits of the higher spatial resolution offered from the next generation of instruments, including TROPOMI, will be discussed
