Soil Heat Flux
Soil heat flux is sometimes ignored because its magnitude is often small relative to the other terms in the energy balance equation. The daily and yearly sums are normally near zero, but daily values can be significant when the soil is heating in the spring or cooling in the fall. Hourly values of the soil heat flux can be large under dry bare soil conditions. Omission of soil heat flux measurements from hourly energy budget analyses will introduce a phase error in the evaluation even though the 24-hour totals will remain unchanged.
