WATERCARBON
This consortium will improve understanding of the controls on carbon, water and energy exchange between arctic terrestrial
ecosystems and the atmosphere
CARBON-ecosystem processing
of carbon
WATER-interactions of
topography, hydrology and vegetation
ENERGY-Seasonality of land-atmosphere coupling
Models-upscaling
-process integration
