- Net radiation splits into latent, sensible and ground heat flux; for grass reference surfaces ground heat flux is about 10% of net radiation by day and 50% at night
- Heat conducts by Fourier's law with thermal diffusivity D = lambda/C, typically 0.2-0.8e-6 m2/s in mineral soils
- The daily temperature wave damps with depth: the amplitude falls by a factor e at d = sqrt(2D/omega), about 0.12 m (daily) and 2.2 m (annual) for D = 0.5e-6 m2/s, leaving under 5% of the surface daily swing below about 0.35 m
