Ground BRDF measurements were acquired by the Remote Sensing Science (RSS)-08 team to aid in the development of advanced spectral vegetation indices. The RSS-08 team measured reflectances at the double-scaffold towers in the Southern Study Area (SSA) Old Black Spruce (OBS) and Old Aspen (OA) sites during IFC-3 in 1994. The RSS-08 team also acquired stereo photography at the SSA-OA, SSA-OJP, and SSA-OBS sites during IFC-3.
