The surface called "surface" means the lower boundary of the atmosphere. "Upward" indicates a vector component which is positive when directed upward (negative downward). The surface latent heat flux is the exchange of heat between the surface and the air, here on account of transpiration. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. Transpiration is the conversion of fluid into vapor by plants.

Transpiration is the process by which water is carried from the roots of plants and evaporates from the stomata. Latent heat flux due to transpiration is the exchange of heat between plant surfaces and the air due to the evaporation and submlimation of transpired water.

Transpiration is the process by which water is carried from the roots of plants and evaporates from the stomata. Evaporation is the conversion of liquid or solid into vapor. (The conversion of solid alone into vapor is called "sublimation".) Latent heat flux due to transpiration is the exchange of heat between plant surfaces and air due to the evaporation and sublimation of transpired water.
