- Observation PAR transmittance fell to about 0.1 after leaf emergence.
- Observation Canopy optical properties changed little until senescence.
- Association Cloud cover showed no evidence of influencing mean canopy transmittance.
- Observation Transient sunflecks introduced great variability.
- Observation Woodland red to far-red fluence rate ratio temporarily increased in late summer.
- Association Leaf transmittance changes correlated with canopy changes and pigment content.
