Arctic Biosphere-Atmosphere Coupling across
multiple Scales (ABACUS)
Why is this SO important for understanding
global change?

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