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.
