is an effort to provide global scale fluxes of carbon, water and energy between terrestrial ecosystems and the atmosphere using  satellite observations.

Remote sensing methods are developed by combining leaf-level studies  with tower-flux measurements of whole-ecosystem fluxes in a diversity of biome types. These methods are then applied using satellite observations to map the metabolism and  physiological activity of ecosystems across the land surface. 

  • Ecophysiological measurements of photosynthesis, transpiration and respiration provide the information needed to develop process-based models that relate remote sensing observations to plant and soil fluxes. 
  • Satellites provide measurements of the timing and status of plant activity as well as weather conditions at the land surface needed as inputs to the remote sensing models. 
  • Micrometeorological towers from around the world provide measurements of whole ecosystem fluxes on a near-continuous basis needed to test the remote sensing methods.
