Science Questions:

Carbon Dynamics:

        CD-Q3 - What are the relative contributions of fluxes from natural and disturbed ecosystems to the net Amazônia-wide flux?
        CD-Q3b - How does selective logging change the storage and cycling of carbon in forests?

Trace Gas and Aerosol Flux:

        TG-Q1 - How are fluxes of trace gases and aerosols between ecosystems (both upland and wetland) and the atmosphere of Amazônia affected by land cover and land use change?
        TG-Q2 - What is the (climatically driven) seasonal and inter-annual variability of trace gas and aerosol fluxes between the atmosphere and different land use and land cover types?
        TG-Q3 - Are losses and gains of carbon from Amazônian ecosystems in forms other than carbon dioxide (e.g. carbon monoxide, methane, volatile organic carbon, organic aerosol) of sufficient magnitude to influence ecosystem carbon balance?
