I am currently working on a FLUXNET synthesis project titled: “Analysis of across-site variability of carbon-flux and -pool relations (e.g. turnover times) derived from chamber and eddy covariance based measurements, as affected by climate, vegetation, and other factors.” This is part of the QUASOM project in our group.
The goal of the study is to derive, as an overall ecosystem diagnostic, the relationships between carbon fluxes and pools across a number of ecosystems and possibly within different ecosystem compartments (e.g. litter, mineral soil). The results of the study would benefit those trying to create and improve models on soil carbon dynamics, by providing empirical constraints on the models. This synthesis would also add to our understanding of spatial variability of SOC dynamics and controls, helping to improve and/or direct future studies on soil carbon cycling.
If you are interested in participating in this project, please contact me. We are always looking for research sites where soil fluxes and carbon pools have been measured.
