The Cloud Absorption Radiometer (CAR) was flown aboard the University of Washington Convair CV-580 research aircraft during the SAFARI 2000 dry season campaign and obtained measurements of bidirectional reflectance-distribution function (BRDF) for a variety of natural surfaces and ecosystems in southern Africa. To measure the BRDF of the surface-atmosphere system, the University of Washington CV-580 banked at a roll angle of ~20° and flew circles about 3 km in diameter above the surface taking approximately two minutes. Multiple circular orbits were acquired over selected surfaces so that average BRDFs could be acquired smoothing out small-scale surface and atmospheric in-homogeneities. In this paper we present results of BRDFs taken over two EOS validation sites: Skukuza tower, South Africa (25.0°S, 31.5°E) and Mongu tower, Zambia (15.4°S, 23.3°E). Additional sites are discussed and include the Maun tower, Botswana (20.0°S, 23.5°E), Sua Pan, Botswana (20.6°S, 26.2°E), Etosha Pan, Namibia (19.0°S, 16.0°E) and marine stratocumulus clouds off the west coast of Namibia (19.0°S, 16.0°E). Results clearly show anisotropy in reflected solar ra-diation over the various surfaces types, savanna, salt pans and cloud. The great-est anisotropy is observed over marine stratus clouds, which exhibit strong for-ward scattering as well as important water cloud scattering features such as the rainbow and glory. The BRDF over savanna is characterized by a distinct back-scattering peak in the principal plane and shows directional and spectral varia-tions. Over the pans the BRDF is more enhanced in the backscattering plane than forward scattering plane and shows little directional variation.
