Abstract

We describe a comparative approach to micrometeorological measurements of surface energy, water vapor, and trace gas fluxes, inwhich mobile eddy correlation towers are moved among sites every 9–14days, allowing both direct and indirect comparison of fluxes amongecosystem types. Structurally distinct ecosystems in Alaskan arctic tundra differed in the relationships between net radiation and surface energyfluxes, whereas structurally similar ecosystems showed constantrelationships, even when they experienced quite different climate.

An intercomparison of two towers simultaneously operated at the same location provided a reference for the systematic error of such comparisons.We suggest general criteria for comparing flux measurements made indifferent ecosystems.
