Evapotranspiration (ET) accounts for the flux of water evaporated at the Earth-atmosphere interface (soil + vegetation + water bodies) and transpired by vegetation through stomata in its leaves as a consequence of photosynthetic processes. Evapotranspiration plays a crucial role in the recycling of precipitation, in soil water availability and consequently on food production. Evapotranspiration is dependent mainly on the solar energy available to vaporize the water and in water content in the soil layers. Because of the dependence on solar energy, ET varies with latitude, season of year, time of day, and cloud cover.

Reference evapotranspiration (ETo) is the evapotranspiration rate from a clearly defined reference surface. The concept was introduced to allow the estimation of the evaporative demand of the atmosphere independently of crop type, crop development or management practices. ETo corresponds to the evapotranspiration from a hypothetical extensive well-watered field covered with 12 cm height green grass having an albedo of 0.23 would experience under the given down-welling short-wave radiation.

Sensible (H) and Latent heat flux (LE) account for the fluxes of energy associated to the exchange of heat by convection (for H) and to the exchange of water vapour (for LE) at the Earth-atmosphere interface (soil + vegetation + water bodies). Accurate measurements of surface heat fluxes at large spatial scales are central to understand land and atmosphere interactions in the context of global warming. They are of great importance in disciplines like weather forecasting, water management, agriculture, hydrology, ecology and global climate monitoring.
