Mars Analog Soil BUG Observations

This data set contains bidirectional reflectance distribution function (BRDF) measurements of 5 Mars soil analogs (AREF_235, AREF_236, AREF_237, AREF_238, and JSC_Mars1). The measurements were acquired by the Bloomsburg University Goniometer (BUG) at Mars Exploration Rover (MER) Panoramic Camera (Pancam) wavelengths (450-990 nm) using the Pancam flight spare filters. The data were provided by Michael Shepard, Bloomsburg University, and archived by the PDS Geosciences Node.
