Abstract
An investigation was carried out to determine the temporal variation in UV canopy transmittance during leaf-out and estimate the UV exposure of the herbaceous layer under the deciduous forest canopy. The spectral reflectance of bark and dead leaves were evaluated on air-dried samples using a Perkin Elmer Lambda 19 spectrophotometers. The canopy transmittance was empirically modeled as a function of time, cloud and solar zenith angle. The herbaceous vegetation exposure impact due to changes in climate indicate that the herbaceous layer vegetation will receive approximately 22% more biologically effective UVB with decreases in 20 DU in stratospheric ozone.
