W. Brutsaert, LAND-SURFACE WATER-VAPOR AND SENSIBLE HEAT-FLUX - SPATIAL VARIABILITY, HOMOGENEITY, AND MEASUREMENT SCALES, Water resources research, 34(10), 1998, pp. 2433-2442
Available methods to determine the sensible and latent heat fluxes fro
m the Earth's land surfaces are still relatively imprecise; this is du
e primarily to the inherent irregularity of the turbulent transport me
chanisms and also to the pronounced variability of most natural land s
urfaces. While great progress has, been made in the study of turbulenc
e, until recently, surface variability has received relatively little
attention in this context. Some thoughts are provided on approaching t
his issue by focusing on the stochastic structure of the land surface
within the framework of homogeneous, i.e., stationary, random function
s. In addition, suggestions are made regarding the likely applicabilit
y of classical concepts by relating the relevant scales of surface var
iability structure to those characterizing turbulent transport in the
atmospheric boundary layer.
