It is an area of permanent drought, where evapotranspiration exceeds precipitation for most of the year.
Since evapotranspiration losses are largely controlled by the meteorological conditions, seasonal evapotranspiration is nearly the same whether yields are high or low.
Thus, remote sensing may enable relatively inexpensive measurement of evapotranspiration over much greater geographical coverage than could be obtained by weather stations alone.
Such deforestation raises temperatures and decreases evapotranspiration at a local level, as well as potentially on a cumulative, regional scale.
High evapotranspiration rates in these climatic zones bring salts in the soil solution to the topsoil where the salts accumulate after water is evaporated.
This also demonstrates the influence of ground vegetation on the overall evapotranspiration process in a coffee plantation.
Actual rates of evapotranspiration fell below maximum values when the soil water deficit exceeded only 20 mm.
This was because they were under the same environmental conditions and so had the same percolation loss and evapotranspiration.
