TITLE: Aspen Aspen-1 Green-Top DESCRIPT
DOCUMENTATION_FORMAT: PLANT
SAMPLE_ID: Aspen-1
PLANT_TYPE: Deciduous Tree
PLANT: Quaking Aspen
LATIN_NAME: Populus tremuloides
COLLECTION_LOCALITY: Boulder, Colorado
ORIGINAL_DONOR:
SAMPLE_DESCRIPTION:
Reflectance measurements of the top surface of a green leaf from a quaking aspen (Populus tremuloides) tree. The single leaf was measured on a black (nearly 0% reflectance) background. The leaf was cut from a tree and stored in a plastic bag two hours prior to measurement. The spectrometer head (bare fiber optic) was held approximately 3 cm from the leaf surface and moved around the area of the leaf as spectra were recorded. This average reflectance was computed from 12 recorded spectra.
