evaporative cooling

Cooling accomplished by evaporating water (usually as a fine spray) in air; as a result, the dry-bulb temperature decreases and the humidity increases; this principle is used in cooling towers and in the cooling of buildings in hot, arid climates.

It is more difficult to detect crop water status by remote sensing in humid climates than in semiarid climates because of limited canopy cooling by evaporation. On the same run that agricultural planes are used to spray pesticides, they can be used to obtain canopy heat signatures to assist in irrigation scheduling.
