Tower and Aircraft Eddy Covariance Measurements of Water Vapor, Energy, and Carbon Dioxide Fluxes during SMACEX

Abstract

A network of eddy covariance (EC) and micrometeorological flux (METFLUX) stations over corn ( Zea mays L.) and soybean Glycine max (L.) Merr. canopies was established as part of the Soil Moisture––Atmosphere Coupling Experiment (SMACEX) in central Iowa during the summer of 2002 to measure fluxes of heat, water vapor, and carbon dioxide (CO 2 ) during the growing season. Additionally, EC measurements of water vapor and CO 2 fluxes from an aircraft platform complemented the tower-based measurements. Sensible heat, water vapor, and CO 2 fluxes showed the greatest spatial and temporal variability during the early crop growth stage. Differences in all of the energy balance components were detectable between corn and soybean as well as within similar crops throughout the study period. Tower network––averaged fluxes of sensible heat, water vapor, and CO 2 were observed to be in good agreement with area-averaged aircraft flux measurements.
