Detailed observations of energetic, hydrological and chemical fluxes at the surface-atmosphere interface are necessary to understand and model coupling within the Arctic climate system. Global and regional models may represent Arctic state variables with relative accuracy, but it has been observed that they consistently fail to represent the observed magnitude and direction of energetic fluxes within the Arctic system. Some results of this failure are highly uncertain projections about the future state of the Arctic cryosphere and biosphere and high uncertainty about the fate of cryospheric carbon in the global atmosphere. To address these poorly constrained processes, coupling between the Arctic atmosphere, land surface and subsurface must be evaluated as an integrated system of energy, moisture and chemical exchange – each with unique observational challenges and process complexities in extreme Arctic environments.
