Abstract This study aimed to accurately estimate daily wheat evapotranspiration using two remote sensing algorithms, Surface Energy Balance System (SEBS) and Algorithm for Land (SEBAL), in central Khuzestan province during 2019–2020. The results of algorithms were compared with lysimeter (as a direct method), FAO-Penman–Monteith (FAO-PM), temperature-based methods (Hargreaves-Samani Blaney-Crid...

10 11 The major problem with high spatial resolution satellite images from Landsat 7 is that 12 imagery is not available very often (i.e. every 16 days or longer) and the coverage area is 13 relatively small (swath width 185km), while images of lower spatial resolution from MODIS are 14 available daily and one image covers a relatively large area (swath width 2,330km). This paper 15 considers t...

abstract evapotranspiration (et) determination is a key factor for irrigation scheduling, water balance, irrigation system design and management and crop yields simulation. therefore many scientists have tried to estimate evapotranspiration in different spatial and temporal scales. remote sensing is a one of new technique in estimation of et in regional scales. so, in this study it’s tried to e...

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...
