Relating Directional Infrared Canopy Temperatures To Plant Water Stress

Abstract

Plant water status is only one of many factors that affect canopy temperature, but it is one of the most important because of its direct effect on vegetation vitality and energy exchanges between the vegetated surface and the atmosphere. which is based on a detailed soil-plant-atmosphere model that predicts directional infrared temperature (IRT) along with carbon, water and energy budgets, provides a means of assessing the likelihood of successfully inverting models to obtain water stress predictions from remote thermal observations. Sensitivity testing.
