Monitoring of water and energy fluxes is a requirement for assessment of climate and anthropogenic effects on natural and agricultural ecosystems [i]. These fluxes consist of the physical transfers between soil, vegetation and atmosphere. In order to describe these transfers, on local, regional or global scale, and the changes taking place in the compartments it is necessary to have measurement...

Producing daily actual evapotranspiration (ET a ) maps with high spatial resolution has always been challenge for remote sensing research. This study assessed the feasibility of producing ET (30 m) sugarcane farmlands Amir Kabir Sugarcane Agro-industry (Khuzestan, Iran) using three different scenarios. In first scenario, reflectance bands Landsat 8 were predicted from moderate imaging spectrora...

Are investigated climate change impacts on glacier melt discharge in the tropical Andes given its relevance to water resources. The means are the investigation of net radiation and potential glacier melt trends. For such purposes is assessed the investigation of the Surface and Energy Balance algorithm (SEBAL) performance, and is carried a practical application to establish the relevance of the...

The culture of açaí (Euterpe oleraceae M.), originating from floodplain areas, was planted on dry land in many properties Pará, Brazil, making necessary the use irrigation. To irrigate adequately with less waste, it is that studies aim at increasing efficiency water this sector, and one ways to do so estimate evapotranspiration (ET). objective study actual daily using Surface Energy Balance Alg...

estimation of evapo-transpiration is necessary in cases such as irrigation planning, determining of evaporation of the water bodies, water balance assessment, estimation of runoff and watershed management and ecological and meteorological studies. evapo-transpiration can be determined precisely using field measurements. however, these methods provide evapo-transpiration just for limited areas f...
