Abstract

In this work two theoretical footprint models and experimental intra-field turbulent fluxes of latent, sensible heat and carbon dioxide are compared. Experimental data are obtained using a mobile eddy covariance station moving it from a discontinuity point, represented by the field edge, towards the centre of the field where a fixed eddy covariance station is placed. The experimental field is a bare soil at Landriano (PV) in the Po Valley, Italy. The experimental measurements show that latent and sensible heat fluxes have a hyperbolically trend across the field, while carbon dioxide flux is characterized by a linear trend. The maximum relative error between theoretical footprint models and turbulent scalar flux measurements is about 18%.
