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
