Book Description
Evapotranspiration (ET) is a critical component of the water and energy balances, and the number of remote sensing-based ET products and estimation methods has increased in recent years. Various aspects of remote sensing of ET are reported in the 11 papers published in this book. The major research areas covered by this book include inter-comparison and performance evaluation of widely used one- and two-source energy balance models, a new dual-source model (Soil Plant Atmosphere and Remote Sensing Evapotranspiration, SPARSE), and a process-based model (ETMonitor); assessment of multi-source (e.g., remote sensing, reanalysis, and land surface model) ET products; development or improvement of data fusion frameworks to predict continuous daily ET at a high spatial resolution (field-scale or 30 m) by fusing the advanced spaceborne thermal emission reflectance radiometer (ASTER), the moderate resolution imaging spectroradiometer (MODIS), and Landsat data; and investigating uncertainties in ET estimates using an ET ensemble composed of several land surface models and diagnostic datasets. The effects of the differences between ET products on water resources and ecosystem management were also investigated. More accurate ET estimates and improved understanding of remotely sensed ET products are crucial for maximizing crop productivity while minimizing water losses and management costs.

Book Description
This edition of Evapotranspiration - Remote Sensing and Modeling contains 23 chapters related to the modeling and simulation of evapotranspiration (ET) and remote sensing-based energy balance determination of ET. These areas are at the forefront of technologies that quantify the highly spatial ET from the Earth's surface. The topics describe mechanics of ET simulation from partially vegetated surfaces and stomatal conductance behavior of natural and agricultural ecosystems. Estimation methods that use weather based methods, soil water balance, the Complementary Relationship, the Hargreaves and other temperature-radiation based methods, and Fuzzy-Probabilistic calculations are described. A critical review describes methods used in hydrological models. Applications describe ET patterns in alpine catchments, under water shortage, for irrigated systems, under climate change, and for grasslands and pastures. Remote sensing based approaches include Landsat and MODIS satellite-based energy balance, and the common process models SEBAL, METRIC and S-SEBS. Recommended guidelines for applying operational satellite-based energy balance models and for overcoming common challenges are made.

Book Description
The book is a thorough presentation of theoretical and applied aspects of the evaporation and evapotranspiration process supported by data from experimental studies. It is written in a way that the theoretical background of evaporation and evapotranspiration estimation is presented in a simplified manner, comprehensive to most technical readers. The book deals with details of meteorological parameters and monitoring sensors which are needed for estimating evaporation and evapotranspiration. Errors in meteorological parameter measurements are also presented. Estimation errors, strengths, weaknesses and applicability of a wide range of evaporation and evapotranspiration estimation methods are presented along with samples of application to a certain region. Application of newer simpler methods is presented. A new technology, remote sensing application to evaporation and evapotranspiration estimation, is presented. The latest interest in the subject, climate change and evapotranspiration is presented in the last chapter. This book will be beneficial to students, hydrologists, engineers, meteorologists, water managers and others.

Book Description
Evapotranspiration (ET) is an important part in surface energy and water balance. ET is the process where liquid water is converted into water vapor and thus removed from sources such as the soil surface, wet vegetation, pavement, water bodies, etc. Transpiration consists of the vaporization of liquid water within a plant and subsequent loss of water as vapor through leaf stomata. Remote sensing based energy balance models are presently most suited Surface Energy Balance Algorithm for Land (SEBAL), a remote sensing based ET model, was applied to Landsat TM imagery in Bankura district, a tropical region in West Bengal with heterogeneous surface conditions, for the estimation of actual ET. SEBAL model follows an energy balance approach of estimation of ET, when the net radiation, sensible heat flux and soil heat flux are known. Input for SEBAL model includes land surface parameters such as surface temperature, NDVI and albedo.

Book Description
The Near East and North Africa (NENA) Region has long faced water scarcity due to natural causes. Still, factors like population growth, food security policies, and socioeconomic development have worsened the situation in recent decades. Climate change and the food insecurity resulting from the war in Ukraine have further strained the already limited water resources in the region. To address these challenges, countries in the NENA Region seek ways to allocate scarce water resources effectively. They aim to improve water accounting, monitor water usage in strategic hydrological systems, and enhance water productivity and efficiency to save and redistribute water. One crucial aspect to consider in these efforts is water consumption, particularly in irrigated agriculture, which utilizes over 85 percent of renewable freshwater resources while remaining vital to the sustainability of the food sector and farming systems. Given the significant spatial scales involved, satellite remote sensing technology has become a valuable tool in determining evapotranspiration–water consumption. The Food and Agriculture Organization (FAO) Regional Initiative on Water Scarcity for the Near East and North Africa (WSI) has gathered top experts in evapotranspiration determination through satellite remote sensing to guide water stakeholders in the region. This initiative has also expanded to other FAO regions through the inter-Regional Technical Platform on Water Scarcity (iRTP-WS). To facilitate knowledge sharing, a series of twenty-five webinars were organized, fostering dialogue between experts and water actors. Additionally, this publication summarizes the outcomes of the webinars and provides further analysis and insights on satellite remote sensing determination of evapotranspiration. The publication aims to update the knowledge and enhance the capacity of water professionals, raise awareness of the strengths and limitations of remote sensing models and databases for evapotranspiration, and clarify operational aspects such as spatial and temporal resolutions and accuracy. Ultimately, it serves as a valuable reference for water actors and professionals working towards sustainable water resource management.
