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,

Projected Evolution of Climatic Aridity in Spain: Robust Signals and Model Uncertainties

International Journal of Climatology, EarlyView.
This study examines the projected evolution of climatic aridity in Spain throughout the 21st century, using the UNEP Aridity Index and CMIP6 simulations under different emission scenarios and global warming levels. Despite model biases, results show a general increase in aridity across the country, particularly in southern regions and the Canary ...

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,

Spatiotemporal Droughts Propagation and Direct Driving Variables Under Climate Change Projections: A Case Study of Tunisia

International Journal of Climatology, EarlyView.
Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under

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
