Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation)...

Potential evapotranspiration (PET) or potential evaporation (PE) is the amount of water that would be evaporated and transpired by a specific crop, soil...

The Standardized Precipitation Evapotranspiration Index (SPEI) is a multiscalar drought index based on climatic data. It was developed by Vicente-Serrano...

equation approximates net evapotranspiration (ET) from meteorological data, as a replacement for direct measurement of evapotranspiration. The equation is widely...

osmosis creating root pressure. It is possible for there to be no evapotranspiration and therefore no pull of water towards the shoots and leaves. This...

each year. The potential evapotranspiration may be large but (in the absence of available water) the actual evapotranspiration may be close to zero. Semi-deserts...

though together they are specifically referred to as evapotranspiration. Total annual evapotranspiration amounts to approximately 505,000 km3 (121,000 cu mi)...

automatic watering. Shade houses provide shading to limit water loss by evapotranspiration. Commercial horticulture is required to support a rapidly growing...

is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of...

balance to estimate aspects of the hydrological cycle. SEBAL maps evapotranspiration, biomass growth, water deficit and soil moisture. Its main creator...

by farmers and growers to measure evapotranspiration (ET) rates of crops at any field location. Evapotranspiration is a measure of all of the water that...

approach to modeling evapotranspiration using an energy balance and the latent heat flux to find evapotranspiration rates. Evapotranspiration (ET) is a part...

logarithmic) biotemperature (mean annual, logarithmic) potential evapotranspiration ratio (PET) to mean total annual precipitation. Further indicators...

estimating reference crop evapotranspiration. The Blaney–Criddle equation is a relatively simplistic method for calculating evapotranspiration. When sufficient...

classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature and precipitation information and is used in...

Isotope measurements indicate transpiration is the larger component of evapotranspiration. Recent evidence from a global study of water stable isotopes shows...

on temperature, both average rainfall and rainfall extremes, and evapotranspiration may affect landslide distribution, frequency and intensity (62). However...

precipitation evapotranspiration {\displaystyle P/E{\text{ ratio}}={\frac {\text{total monthly precipitation}}{\text{evapotranspiration}}}} Similarly...

METRIC, a model that uses Landsat satellite data to compute and map evapotranspiration (ET) in climatology/meteorology The word metric is often used to mean...

addition to the precipitation level, its combination with potential evapotranspiration defines a steppe climate. Steppe can be classified by climate: Temperate...

precipitation usually decreases in both the winter and summer due to higher evapotranspiration. Toward the polar latitudes, total moisture usually increases; for...

of water between reservoirs tends towards upwards movement through evapotranspiration and downward movement through gravity. The diagram also shows how...
