Arctic Biosphere-Atmosphere Coupling across multiple Scales

(ABACUS)

Why is this SO important for understanding global change?

Carbon stocks

Permafrost

Hydrology

Km3 yr-1 discharge

Energy balance

Current snow (May)Projected snow (2080)

ENERGY

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

Field campaigns

A multiscale approach

Innovative approachesto quantifying C cycling
