      Surface Moisture flux and latent heat flux. Evaporation, E, can be treated similarly. Again we want to use a variable that is conserved unless there are sources or sinks. In the case of water vapor, such a variable is the specific humidity, q. The eddy correlation method yields (10) The gradient flux form is (11) The bulk aerodynamic form is (12)

      Q* is the net radiation term, H is the sensible heat flux term, LE is the latent heat flux term and G is the soil heat flux term (Robinson and Henderson-Sellers 1999). Studies that involve measurements of the Earth’s energy budget can be complicated by several factors.

      Latent heat flux (W/m2). Figure 5. Sensible heat flux (W/m2). Finally, lets look at changes in ground temperature and canopy temperatures. We see results that are similar to the heat fluxes. Figure 6 shows the temperature of the ground, looking at it we can see that grasses have the highest temperatures, then shrubs, and crops have the lowest ...

      Additionally, the latent heat flux is also a function of humidity so that on a calm humid day the transfer of both sensible and latent heat fluxes will be less than it would be for windy and dry conditions. 10-11. On a clear still night over land, the surface temperature usually (increases, decreases) if a low cloud moves overhead. Explain.

      Bowen Ratio: the ratio of the sensible heat flux to the latent heat flux. Latent Heat Flux: the transfer of latent heat (heat released or absorbed by water) between the surface and the air, or vice versa. Net Radiation: the net difference in downwelling and upwelling solar plus terrestrial radiation.

      Soil latent heat flux was calculated from the differences between LE and LEc. These measurements were coupled with radiation measurements at the soil surface to partition the energy balance into soil and canopy components every hour throughout the daytime. Daily energy balance was strongly influenced by sensible heat flux transfer, and the ...
