Lunar Spectroscopy Data

This data set consists of reflectance spectra of small lunar areas measured in 120 spectral channels from 0.62 to 2.6 micrometers using the McCord circular-variable-filter (CVF) near-infrared photometer. The data were acquired using the 2.2 m telescope on Mauna Kea, Hawaii. The data were provided by the Keck/NASA Reflectance Experiment Laboratory (RELAB) at Brown University and archived by the PDS Geosciences Node.
