| Outline of Final Research Achievements |
A new method to measure local heat exchange (flux) in the plant canopy was developed to understand the heat dynamic in the canopy, which affects crop damage by high temperatures. Surface renewal analysis was applied to a rice, maize and soybean canopies to obtain spatial variation in sensible heat flux from the measurements of air temperature. The results suggest that i) not all turbulent structures penetrate deeply into canopies, and ii) a duration between the ejection of turbulent structures and commencement of next structures is longer at lower layer in the canopies. Based on above surface renewal analysis, we developed a simple equipment to measure the profile of heat flux density in the plant canopy.
