Evapotranspiration Estimation with Remote Sensing and Various Surface Energy Balance Algorithms—A Review

摘要: Abstract: With the advent of new satellite technology, radiative energy exchanges between Sun, Earth, and space may now be quantified accurately. Nevertheless, much less is known about magnitude flows within climate system at Earth’s surface, which cannot directly measured by satellites. This review surveys basic theories, observational methods, different surface balance algorithms for estimating evapotranspiration (ET) from landscapes regions with remotely sensed temperatures, highlights uncertainties limitations associated those estimation methods. Although some these were built up specific land covers like irrigation areas only, methods developed other disciplines hydrology meteorology, are also reviewed, where continuous estimates in time needed. Temporal spatial scaling issues use thermal remote sensing discussed. A based approaches presented. The main physical bases assumptions Some results shown on a rice paddy Chiayi Plain Taiwan using data.
