Representativeness Of Eddy-Covariance Flux Footprints For Areas Surrounding Ameriflux Sites, Housen Chu, Timothy Arkebauer, Dave P. Billesbach, Hideki Kobayashi, Thomas J. Kolbe, Gregory Starr, Andrew Suyker, 63 Other Coauthors

Department of Agronomy and Horticulture: Faculty Publications

Large datasets of greenhouse gas and energy surface-atmosphere fluxes measured with the eddy-covariance technique (e.g., FLUXNET2015, AmeriFlux BASE) are widely used to benchmark models and remote-sensing products. This study addresses one of the major challenges facing model-data integration: To what spatial extent do flux measurements taken at individual eddy-covariance sites reflect model- or satellite-based grid cells? We evaluate flux footprints—the temporally dynamic source areas that contribute to measured fluxes—and the representativeness of these footprints for target areas (e.g., within 250–3000 m radii around flux towers) that are often used in flux-data synthesis and modeling studies. We examine the land-cover composition …
