Abstract:
Flux-variance approaches for latent and sensible heat flux using eddy covariance (EC) tower data from the Evapotranspiration and Agricultural Remote Sensing Experiment (BEAREX08) are evaluated for irrigated and non-irrigated cotton,a pasture grassland surface, a fallow wheat field and a 10 m EC tower influenced by both irrigated and non-irrigated sources. BEAREX08 was conducted at the Conservation Production Research Laboratory (CPRL) in Bushland , TX a region known for significant advection with strong winds. It is unknown how conditions of strong advection will affect flux-variance relationships developed from Monin-Obukhov similarity theory using turbulence data collected over extensive and homogeneous non-advective landscapes. A discussion of the effects of advection on these relationships and potential use of flux-variance methods in this type of environment will be presented
