Landflux.org 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.
