EARLY RESULTS FROM TES

Daniel J. Jacob, Professor of Atmospheric ChemistryHarvard University

TES Principal Investigator: Reinhard Beer, NASA/JPL

TES is providing the first global data on tropospheric ozone including vertical profiles and gases that track ozone production

These data enable a better understanding of the sources controlling ozone and the global impact of human activity
