      Figure 18: Heat Flux & Controller Discontinuities. First note that the data has negative heat flux values removed by setting them to 0. SODDIT does not return valid data if the outer surface of the ablator material rises above, then falls below the ablation temperature. Negative heat flux values make this occur very often, and had to be removed.

      units: kg m-3 J kg-1 K-1 m s-1 K = J m-2s-1. So . 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, suych a variable is the specific humidity, q. The eddy correlation method yields.

      This gives a latent heat flux . Thus according to (4.13) with the assumption that , one can write H = 200-40-122.5 = 37.7 W/m2. (b) The Bowen ratio was (c) The atmosphere was unstable because , which means that the sensible heat flux was upward, and . (d) The ground was warming because , that is the heat flux into the ground was positive.

      heat flux, q. q = - k dT/dz. Units of heat flux = Wm-2. which is equivalent to . Js-1m-2, and k is the thermal conductivity (Wm-1K-1). The average heat flow from the Earth gives a q of approximately 0.08Wm-2 (equivalent to 80mWm-2). But the flow is very uneven. Some areas, such as volcanoes and mid-ocean ridges have very high q ~400 mWm-2.
