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.

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 ...

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.

Spatio-temporal characteristics of meteorological drought based on the MCI of Penman–Monteith

Natural Hazards, 2023
Abstract The severity of global climate change is increasing, resulting in more frequent occurrences of drought disasters. Accurate evaluation of Spatio-temporal changes in drought using drought indices is of significant practical importance. This study employed the MCI based on Penman-Monteith, in combination with Kriging spatial interpolation,

The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, EarlyView.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...
