The central feature of the AmazonFACE program is a field experiment of unprecedented scope that will expose an old-growth Amazon forest to the CO2 concentration of the future. A Free-Air CO2 Enrichment (FACE) experimental facility will be established at the ZF2 research site is near Manaus, Brazil.  

We have laid out plots and conducted extensive site characterization, but we do not yet have sufficient funding to build the experimental infrastructure and start the experiment. Please see the project website for a full description of the project.
