Parabola directional field radiometer for aiding in space sensor data interpretationsA unique field radiometer, called the Parabola, was developed to accurately measure the multidirectional incoming and outgoing spectral radiances for a variety of earth surface types; these range from rangeland vegetation to ice and snow. It is found that bidirectional reflectance characteristics are not constant for a given type of vegetation. There can be substantial changes in the anisotropic expression with changes in the solar zenith angle and vegetation conditions.
