摘要

Measurements of directional brightness surface temperature were performed over vineyards using an airborne thermal infrared camera. These measurements reveal differences of up to 15 $^{ circ}hbox{C}$ according to the viewing direction and are critically impacted by vine row orientation. The contribution of each element of the canopy (sunlit/shaded soil and vegetation) to the directional anisotropy is illustrated using a simple 3-D model and the POV-Ray ray-tracing tool.
