In semi-arid and arid regions, crops face elevated atmospheric demands and endure prolonged periods of moderate to severe water scarcity. In this context, this study investigated the effectiveness of the photochemical reflectance index (PRI) and a normalized surface temperature index (Tnorm) for proxy detection of the water stress of winter wheat crops. Furthermore, the potential of PRI for characterizing

Coupled models of water and carbon cycles from leaf to global: A retrospective and a prospective Agric. For. Meteorol. (IF 5.6) Pub Date : 2024-09-13 Ying-Ping Wang, Lu Zhang, Xu Liang, Wenping Yuan
Our understanding of water and carbon cycles and their coupling has advanced significantly over the last six decades. In this review, we will examine the progress made since the 1960s and explore how key developments in the studies of water and carbon cycles on land have influenced the way we model these two cycles from leaf to global scales. We will particularly focus on the Penman-Monteith equation

MONTPEL: A multi-component Penman-Monteith energy balance model Agric. For. Meteorol. (IF 5.6) Pub Date : 2024-09-12 Rami Albasha, Loïc Manceau, Heidi Webber, Michaël Chelle, Bruce Kimball, Pierre Martre
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, a multi-component Penman-Monteith model that
