Assessment of downscaling methods for estimating evapotranspiration by combining MODIS and Landsat 8 images [PDF]

open access: yesفناوری‌های پیشرفته در بهره‌وری آب, 2022
Evapotranspiration (ET) is one of the most important parameters in agricultural water management which has spatial and temporal variations. Remote sensing-based algorithms of ET estimation have been applied in several studies.

Analysis of Climatic Factors Affecting Actual Evapotranspiration through Weighted Regression Model. Case study: Eastern Towns of Uremia Lake [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2021
Introduction For the first time, Faddingham presented a geographic weight regression model. He tried to study the aspects of space heterogeneity. After that, Bronson examined the relationship between housing prices and areas.

Using SEBAL to Investigate How Variations in Climate Impact on Crop Evapotranspiration [PDF]

open access: yesJournal of Imaging, 2017
Water allocation to crops, and especially to the most water intensive ones, has always been of great importance in agricultural processes. Deficit or excessive irrigation could create either crop health-related problems or water over-consumption, respectively.

Estimate of evapotranspiration in eastern Amazonia using SEBAL

open access: yesRevista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences, 2013
Neste estudo, foram analisadas as estimativas de fluxos de calor latente e sensível através do Acqua/MODIS para a Floresta Nacional de Caxiuanã, Melgaço-Pa. Para tal, utilizaram-se dados de imagens orbitais combinados aos dados observacionais do Projeto LBA (Experimento de Grande Escala da Biosfera-Atmosfera na Amazônia), coletados em 2008 na torre ...

A MODIS-Based Energy Balance to Estimate Evapotranspiration for Clear-Sky Days in Brazilian Tropical Savannas

open access: yesRemote Sensing, 2012
Evapotranspiration (ET) plays an important role in global climate dynamics and in primary production of terrestrial ecosystems; it represents the mass and energy transfer from the land to atmosphere.
