"FLUXNET is a global network of micrometeorological flux measurement sites that measure the exchanges of carbon dioxide, water vapor, and energy between the biosphere and atmosphere. At present over 140 sites are operating on a long-term and continuous basis. Vegetation under study includes...

Global, spatially and temporally explicit estimates of carbon and water fluxes derived from empirical up-scaling eddy covariance measurements would constitute a new and possibly powerful data stream to study the variability of the global terrestrial carbon and water cycle. Jung et al (2009)

The Gravity Recovery and Climate Experiment (GRACE) refers to a pair of NASA satellites that has flown in low-Earth orbit since 2002. The satellites use a precise microwave ranging system to measure the distance between themselves due to gravitational acceleration. Onboard GPS instruments determine...
