Microclimat, eau et production
It is generally known that the whole of climatic factors affects directly the principal biological functions and the processes influencing crop yield. However, the control of these factors remains very difficult. Research is carried out adapting different crops to the average daily climatic characteristics and to their seasonal evolution instead of modifying the crops genetically and physiologically. Since all times the control of the factor water, not from rainfall but from irrigation, gives possibilities to modify directly the characteristics of the microclimate in the plant canopy.

Flux heterogeneity and evapotranspiration partitioning in a sparse canopy: the fallow savanna
Abstract This paper focuses on in situ measurements obtained during the intensive observation period of the HAPEX-Sahel experiment. Micrometeorological measurements and trunk sap flow monitoring were combined to analyse transfer characteristics of a fallow savanna site within the East Central Supersite. Results show that the shrub canopy heterogeneity induces a large spatial variability of solar irradiance, soil heat flux and sensible and latent heat fluxes at the grassland level. This variability is induced by both a “shade effect” and a “wake effect”. Both shrubs and grassland provide sources of vapour, but the partitioning of evapotranspiration between these two components varies conside…

Soil evaporation monitoring : a possible synergism of microwave and infrared remote sensing
Abstract Microwave remote sensing allows the measurement of the water content (θs) at the soil surface within a layer of a few centimetres. When combined with climatic data, θs is a relevant quantity to estimate the evaporation of bare soils. The implementation of a simple daily evaporation (Ed) model on bare soils based on a knowledge of θs is analysed. In order to cover a wide range of soil, soil moisture and climatic conditions, the analysis was carried out on a set of data simulated by a mechanistic model of heat and water flows in the soil. Propagation error analysis on the inputs (θs, daily potential evaporation and wind velocity) of the simple model shows that an accuracy of ± 1.5 mm…
Interactions surface continentale/atmosphère : l'expérience HAPEX-Sahel
L'évolution saisonnière des termes du bilan radiatif, du bilan d'énergie et la production primaire d'une savane humide d'Afrique de l'Ouest (Lamto, Côte d'Ivoire) a été suivie dans le cadre du programme SAvanes à Long Terme (SALT). Ces données ont permis de développer un modèle de simulation des échanges surface/atmosphère en savane humide, basé sur les relations fonctionnelles existant entre la production et la phénologie de la savane d'une part, et les bilans d'énergie et hydrique de ce type de surface d'autre part. Ce modèle est issu du couplage de deux sous-modèles fonctionnant au pas de temps journalier et utilisant des variables climatiques standard en entrée : le modèle de bilan d'én…
