Comparison of methods for estimating reference evapotranspiration (ETo) for Rahuri region

Journal of Agrometeorology, 2015
Penman Monteith (FAO56-PMM), Modified Penman FAO-24 (MPM), Hargreaves-Samani (HSM), FAO-24 Pan Evaporation (FPEM), Blaney-Criddle (BCM) and FAO Radiation (FRM) methods were used for estimation of ETo for Rahuri region.

Reference crop evapotranspiration derived from geo-stationary satellite imagery: a case study for the Fogera flood plain, NW-Ethiopia and the Jordan Valley, Jordan [PDF]

First results are shown of a project aiming to estimate daily values of reference crop evapotranspiration ET0 from geo-stationary satellite imagery. In particular, for Woreta, a site in the Ethiopian highland at an elevation of about 1800 m, we tested a ...

The coordination of dehydration tolerance and avoidance in oaks is mediated by leaf habit across a precipitation gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests worldwide are increasingly impacted by drought due to climate change, prompting plants to adapt through dehydration tolerance (DT) and avoidance (DA), two distinct physiological strategies.

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,

Clearing the Air: How Fine Particulate Matter Regulations Reshape Farmland Values in U.S. Corn and Soybean Regions

Journal of Agricultural Economics, EarlyView.
ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

Correlación entre la evaporación en tina y la evaporación calculada en cinco estaciones climatológicas Correlation between pan evaporation and the evapotranspiration calculated from five climatological stations in Venezuela

Bioagro, 2005
Con la finalidad de conseguir fórmulas de evapotranspiración más adaptadas a diferentes zonas de Venezuela, se utilizaron las ecuaciones de Penman-Monteith, Hargreaves, García-López, Thornthwaite y Blaney-Criddle, para correlacionar la ETo con la ...

Accuracy of Potential Evapotranspiration Models in Different Time Scales [PDF]

Revista Brasileira de Meteorologia
Know the precision of potential evapotranspiration models in different agronomic and climatic conditions is useful for irrigated agriculture. Therefore, we aimed to compare 18 methods of estimation of ETP with the Penman-Monteith (FAO-56) method, at ...

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.
