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)
Key Strengths:
- Global coverage at spatial resolution comparable to global climate models. Includes uncertainty estimates.
Key Limitations:
- Upscaling is still hampered by a variety of challenges such as limited ability to account for effects of disturbance and/or site history, and lagged environmental effects (Jung et al. 2011)
