The theoretical maximum amount of water vapor that can be convyed to the atmosphere by the combined processes of evaporation and transpiration by a surface covered by green vegetation with no lack of available water in the soil.
Water loss that will occur if at no time there is a deficiency of water in the soil for use of vegetation.
That amount of moisture that, if it were available, would be removed from a given land area by evaporation and transpiration.
The amount of water that could be evaporated or transpired if it were available.
Maximum quantity of water capable of being lost, as water vapor, by a continuous stretch of vegetation covering the whole ground and well supplied with water.
The maximum amount of soil evaporation and transpiration from a well-irrigated crop for a given set of environmental conditions.
the amount of water that would be lost from a portion of the Earth's surface through evaporation and transpiration over a given period of time if the water were available
The amount of water that evapotranspiration would remove from a specific site if an ample supply of water was available. See evapotranspiration.
maximum quantity of water capable of being evaporated in a given climate from a continuous stretch of vegetation (i.e., includes evaporation from the soil and transpiration from the vegetation of a specified region in a given time interval, expressed as depth)
Water loss which will occur if at no time there is a defiency of water in the soil for use by vegetation and for evaporation. Varies by season.
The amount of moisture which, if available, would be removed from a given land area by evapotranspiration. Expressed in units of water depth.
The rate of which water, if available, would be removed from the soil and plant surface expressed as the rate of latent heat transfer per square centimeter or depth of water. For comparative purposes potential evapotranspiration refers to a well-watered crop like alfalfa (lucerne) with 30 to 50 centimeters of top growth and about 100 millimeters of fetch under given climatic conditions unless otherwise defined.
Is a measure of the ability of the atmosphere to remove water from the surface through the processes of evaporation and transpiration assuming no limitation on water supply.
