Description:
The goal of this study is to scale aircraft measured fluxes of sensible and latent heat to the North Slope of Alaska and
develop high resolution flux maps. For this purpose we analyzed an eddy-covariance data set obtained by the research
aircraft POLAR 5 as part of the AIRMETH-2012 campaign, and investigated the spatial patterning of energy fluxes.
Environmental response functions between flux observations and corresponding biophysical and meteorological drivers
were estimated using a combination of time-frequency decomposition, dispersion modeling and machine learning. The
extracted relationships are then used to scale observational data across heterogeneous Arctic landscapes, thus improving
the spatial coverage and representativeness of the energy fluxes. Maps of projected energy fluxes are used to asses
energy partitioning in northern ecosystems and to determine dominant energy exchange processes of permafrost area.
