 REFLECTANCE
Dr. Glen Ritchie of the University of Georgia has used model
SPEC-PAR/NIR to take
reflectance measurements in cotton fields and estimate
defoliation. Chlorophyll gives plant leaves a
reflectance spectrum characteristically different from that
of soil.
Reflectance measurements
can be reported in µmol m-2 s-1, W m-2,
or as a relative value.
