Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Nonlinearities of Penman and Penman-Monteith Equations across Multiple Timescales

, 2023
The nonlinear Penman and Penman-Monteith equations, widely used for estimating surface evapotranspiration at regional and global scales, were derived from turbulent transport of heat fluxes and thus apply to subhourly scale. However, these equations have been directly applied with hydrometeorological variables averaged at longer time intervals, leading

Modification of FAO Penman–Monteith equation for minor components of energy [PDF]

Hydrology Research, 2018
Abstract The conventional Food and Agriculture Organization of the United Nations (FAO) Penman–Monteith (P-M) equation requires knowledge of the available energy to estimate reference evapotranspiration (ETo); however, it is common to ignore the minor energy components (MECs).

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy

International Journal of Climatology, EarlyView.
This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...

Montpel: A Multi-Component Penman-Monteith Energy Balance Model

Agricultural and Forest Meteorology
Mechanistic modelling is gradually replacing empiricism in crop models, focusing on leaf-level physiological processes. This shift necessitates simulating crop surface temperature at infra-canopy sub-daily scales but many crop models still rely on empirical formulations for canopy temperature estimation, typically on a daily basis. We developed MONTPEL,

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

International Journal of Climatology, EarlyView.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...
