Field maple (Acer campestre)
Click on tabs below to view how radiative performance can vary within a tree species when the factors below change:
Solar Altitude
Horizontal Orientation
Vertical Orientations
Solar Altitude
“Tree crown transflectance increases as solar altitude rises”
Horizontal Orientation
“Tree crown transflectance is the highest on the sunlit side of trees, and lowest on the shade side”
Vertical Orientations
(1) Vertical orientation aligned with the solar azimuth angle
“The strongest tree crown transflection was found primarily towards the sky on the sunlit side of trees rather than towards the zenith”

(2) Vertical orientation aligned perpendicular to the solar azimuth angle
“The strongest tree crown transflection was found primarily towards the sky on the sunlit side of trees rather than towards the zenith”
