BUSCADOR RECOLECTA

The earlier formulation based on surface renewal (SR) analysis for estimating the sensible (or buoyant) heat flux (H) of a surface without requiring calibration involved canopy parameters to simultaneously estimate H and the friction velocity (u*). A SR-based formulation is derived that allows estimating u* and subsequently H that, at most, involves the zero-plane displacement. Regardless of the measurement height above the canopy and the stability case, u* and H estimates were closed to values measured using the eddy covariance method for either homogeneous or sparse (orchards) canopies. The proposed SR analysis can be potentially considered for gap filling in half-hourly eddy covariance series of u* and H and to estimate parameters useful for land surface modeling, such as the roughness length for momentum, the roughness lengths for momentum, and heat and the turbulent Prandtl number., The author gratefully acknowledges R.
