On the Brutsaert temperature roughness length model for sensible heat flux estimation
The scalar roughness length for temperature, z0h, is necessary to estimate the sensible flux from atmospheric surface layer similarity theory in conjunction with skin temperature measurements. A theoretical relationship for z0h as a function of the roughness Reynolds number z01 which was developed by Brutsaert [1975] for rough-bluff surfaces is often used to link infrared skin temperature measu...
متن کاملThe Sea Spray Contribution to Sensible Heat Flux
Direct numerical simulations (DNS) of turbulent Couette flow are combined with Lagrangian point-particle tracking to investigate the effects of a dispersed phase on bulk passive heat transport when the two phases can exchange bothmomentumand sensible heat. The idealized setup allows a fixed number of particles, without the influence of gravity, to be transported by carrier-phase motions across ...
متن کاملEstimation of surface sensible heat flux using dual angle observations of radiative surface temperature
In this study, dual angle observations of radiative surface temperature have been used in conjunction with a two-layer model to derive sensible heat flux over a sparsely vegetated surface. Data collected during the semi-arid-land-surface-atmosphere program (SALSA) over a semi-arid grassland in Mexico were used to assess the performance of the approach. The results showed that this approach led ...
متن کاملSurface renewal method for estimating sensible heat flux
For short canopies, latent energy flux may be estimated using a shortened surface energy balance from measurements of sensible and soil heat flux and the net irradiance at the surface. The surface renewal (SR) method for estimating sensible heat, latent energy, and other scalar fluxes has the advantage over other micrometeorological methods since the method requires only measurement of the scal...
متن کاملScaling Flux Tower Observations of Sensible Heat Flux Using Weighted Area-to-Area Regression Kriging
Sensible heat flux (H) plays an important role in characterizations of land surface water and heat balance. There are various types of H measurement methods that depend on observation scale, from local-area-scale eddy covariance (EC) to regional-scale large aperture scintillometer (LAS) and remote sensing (RS) products. However, methods of converting one H scale to another to validate RS produc...
