Our work in atmospheric composition has been critical in understanding ozone photochemistry and the ozone “hole.” Seminal experiments such as the Stratospheric Aerosol Measurement (SAM), the Stratospheric Aerosol and Gas Experiment (SAGE) and the Halogen Occultation Experiment (HALOE) have provided international scientists with information about the vertical structure of the ozone hole, the role of atmospheric dynamics, and assessments of its long-term changes. SAGE III on ISS, launched in February, will add to that data record from its Earth-observing perch on the International Space Station.
