Deriving potential evapotranspiration from satellite-based reference evapotranspiration, Upper Tekeze Basin, Northern Ethiopia

Evapotranspiration from Northern Semiarid Grasslands

Proper grazing management reduces ET from grasslands by reducing transpiration losses and grazingManagement of forage production for livestock grazing on semiarid induced surface energy relationships that reduce evapograsslands depends on water availability. Evapotranspiration (ET) ration (Svejcar and Christiansen, 1987; Wraith et al., was measured using the Bowen ratio energy balance method on...

Spatiotemporal Variations of Reference Crop Evapotranspiration in Northern Xinjiang, China

To set up a reasonable crop irrigation system in the context of global climate change in Northern Xinjiang, China, reference crop evapotranspiration (ET0) was analyzed by means of spatiotemporal variations. The ET0 values from 1962 to 2010 were calculated by Penman-Monteith formula, based on meteorological data of 22 meteorological observation stations in the study area. The spatiotemporal vari...

Possibilities of Deriving Crop Evapotranspiration from Satellite Data with the Integration with Other Sources of Information

Assessing interannual variability of evapotranspiration at the catchment scale using satellite‐based evapotranspiration data sets

[1] The catchment water‐energy balance at the interannual scale remains a challenge for bridging the important gap in our knowledge of the hydrologic cycle. This study investigates interannual evapotranspiration (ET) variability and water‐energy balance at over 547 catchments across the contiguous United States in different climate zones. The investigation is based on ET data estimated from sat...

Monitoring Cotton Crop Evapotranspiration Based On Satellite Data

The water demand to meet seasonal and long-term water needs in Thessaly, central Greece, is related to historical semi-arid conditions in the region, which is the main agricultural area of the country. In this paper irrigation water requirements are assessed through the estimation and monitoring of crop evapotranspiration ETc for cotton fields in Thessaly. Remotely sensed data are used to delin...
