Estimativa da evapotranspiração de referência (ETo padrão FAO), para Minas Gerais, na ausência de alguns dados climáticos [PDF]

Engenharia Agrícola, 2015
A equação para determinar a evapotranspiração de referência (ETo), método de Penman-Monteith, parametrizada pela FAO (PM-FAO56), requer dados que, muitas vezes, não estão disponíveis na maioria das estações climatológicas.

Evaluation of FAO-56 Penman-Monteith Model with Limited Data and the Valiantzas Models for Estimating Grass-Reference Evapotranspiration in Sahelian Conditions

Journal of Irrigation and Drainage Engineering, 2016
AbstractAccurate determination of grass-reference evapotranspiration (ETo) is very important for agricultural, hydrological, and environmental studies, especially under increasing water scarcity and climate mitigation conditions. The FAO-56 Penman-Monteith (FAO-PM) model is renowned for being the most accurate model; however, it requires a full climate

Intensifying Drought Patterns and Agricultural Water Stress in Erbil Governorate, Iraq: A Spatiotemporal Climate Analysis

Global Challenges, Volume 10, Issue 1, January 2026.
ABSTRACT Drought is a prolonged lack of rainfall that causes water shortages for agricultural land by reducing soil moisture and limiting crop yields. This study assesses the impacts of drought in Erbil, Iraq, using 28 years of data from the southern, central, and northern regions.

Linking remote sensing with crop modeling for yield and nitrate leaching predictions in Minnesota

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Upscaling crop yield and nitrate‐N leaching loss from experimental sites to large areas under alternative crop rotations is crucial for assessing strategies and setting goals to protect groundwater quality at a regional scale. Nitrogen (N) rate field trials were used to calibrate the Environmental Policy Integrated Climate (EPIC) model for ...

Parameterization of Evapotranspiration Estimation for Two Typical East Asian Crops [PDF]

, 2017
Estimation of evapotranspiration plays an important role in understanding the water cycle on the earth, especially the water budget in agricultural ecosystems. The parameterization approach of the Penman-Monteith-Katerji-Perrier (PM-KP) model, accounting

Assessing the Impact of Land‐Use Types on Historical Dryness/Wetness Trends Over Global Land Areas

International Journal of Climatology, Volume 46, Issue 1, January 2026.
Land‐use change during 1901–2014 induced significant standardised precipitation evapotranspiration index (SPEI) wetting trends across midlatitude regions. Dryness and wetness responses are attributed to specific land‐use types using ridge regression.

Interpretable Temperature‐Based Deep Learning for Evapotranspiration: SHAP‐Based Feature Analysis in CNN‐GPU

Meteorological Applications, Volume 33, Issue 1, January/February 2026.
A comprehensive analysis of a computational model based on convolutional networks (CNN) using graphics processing units (GPU) was developed in the present study for reference evapotranspiration (ETo). The CNN‐GPU architecture demonstrates the high accuracy of the model by schematically showing the data flow from input to output, including convolutional
