About the Carbon Team

Carbon Group Working Areas:

  • Satellite-based greenhouse gas observations (primarily carbon dioxide and methane)
  • Carbon flux inverse modeling

 

Key Science Goals:

  • A better understanding of the present state of the earth’s carbon cycle, and the contribution of the biosphere to carbon cycling at regional scales.
  • Observing changes to the earth’s carbon cycle in the era of climate change.
  • Feasibility of monitoring anthropogenic emissions of greenhouse gases from satellites

 

Primary Projects:

  • Orbiting Carbon Observatory 2 and 3 (with NASA JPL)
  • GeoCarb (with NASA and the University of Oklahoma)
  • ACT-America field campaign (with NASA and Penn State)
  • Designing optimized space-based GHG observing systems (with NASA Goddard)
