Curriculum Vitae:

John Worden

My research interests include remote sensing of tropospheric trace gases and their use for investigating the global carbon and water cycles, atmospheric chemistry and their interactions.

Current Responsibilities:

  • Member of the Aura TES Science Team (TES Principal Investigator Emeritus)
  • Member of the OCO-2 Validation Team
  • Member GEOCAPE Working Group
  • TEMPO Mission Standing Review Board Science Lead

  • Ph.D. in Physics, University of Colorado (1996)
  • B.S. in Physics, University of California at Santa Cruz (1990)

Research Interests
  • Remote sensing of tropospheric composition (Ozone, HDO/H2O, CH4, CO2, CO, PAN, OCS).
  • Processes controlling tropical convection
  • Role of anthropogenic emissions, land-use changes, and natural forcings on the global carbon and water cycles.
  • Dynamics and Chemistry of the North American and Asian Monsoons.


The Hyperspectral Thermal Emission Spectrometer

OCO-2 - Orbiting Carbon Observatory Icon OCO-2 - Orbiting Carbon Observatory
The Orbiting Carbon Observatory-2 (OCO-2) is a mission designed to make precise, time-dependent global measurements of atmospheric carbon dioxide (CO2) from an Earth orbiting satellite.

TES (Tropospheric Emission Spectrometer) is one of four science instruments aboard NASA's Aura satellite, which was launched from Vandenberg Air Force Base, California on July 15, 2004.
