Optimizing radiation and temperature models to estimate reference plant evapotranspiration [PDF]

محیط زیست و مهندسی آب
To estimate potential evapotranspiration, many relationships based on the climatic conditions of different regions have been proposed by researchers, which need to be evaluated and calibrated before applying them to specific locations.

From Rare to Recurrent: Intensifying Hot–Dry Extremes Across Romania

International Journal of Climatology, EarlyView.
Romania has undergone a marked shift toward more frequent and spatially extensive compound hot–dry months since the 1990s, with persistent hotspots in the eastern Moldavian Plateau and the lower Danube–Bărăgan–Black Sea lowlands and comparatively buffered conditions at higher elevations.

Evapotranspiration Model-based Scheduling Strategy for Baby Pakchoi Irrigation in Greenhouse

HortScience, 2020
Water management is one of the most important operations in greenhouse baby leaf production. However, growers mainly irrigate the plants based on experience, which generally leads to yield loss, uneven quality, and low water-use efficiency.

The sensitivity of the PDSI to the Thornthwaite and Penman-Monteith parameterizations for potential evapotranspiration [PDF]

Journal of Geophysical Research, 2011
[1] Potential evapotranspiration (PET) is one of the inputs to the Palmer Drought Severity Index (PDSI). A common approach to calculating PDSI is to use the Thornthwaite method for estimating PET because of its readily available input data: monthly mean temperatures.

Determining the Optimal Water Storage Depth of Apple Orchards in the Chinese Loess Plateau: Balancing Soil Desiccation Mitigation, Plant Utilization, and Engineering Construction

Land Degradation &Development, EarlyView.
ABSTRACT Deep‐rooted plantations are central to dryland ecological restoration, yet their long‐term cultivation drives widespread deep soil desiccation, threatening ecosystem sustainability. While artificial water replenishment is a key deep soil desiccation mitigation strategy, the depth‐dependent positional effect of stored water on eco‐hydrological ...

Evapotranspiração de referência com base na radiação solar global estimada pelo método de Bristow-Campbell Reference evapotranspiration based on solar radiation estimated by the Bristow-Campbell model

Engenharia Agrícola, 2010
A quantidade de água a ser aplicada em sistemas de irrigação é normalmente calculada com base na evapotranspiração de referência (ETo) da região. Vários métodos podem ser empregados para o cálculo de ETo, sendo o de Hargreaves um dos mais adotados.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Evaluation of six empirical evapotranspiration equations - case study: Campos dos Goytacazes/RJ Avaliação de seis equações empíricas de evapotranspiração diária - estudo de caso: Campos dos Goytacazes/RJ

Revista Brasileira de Meteorologia, 2012
The evapotranspiration is a component of the water balance constituting a major challenge in its quantification. The complex physical processes involved in its effective determination on a large scale have spurred scientists to often make use of ...
