| Description: The phase_angle element provides a measure of the relationship between the instrument viewing position and incident illumination (such as solar light). Specifically, it is the angle, measured at the intercept point, between a vector in the direction of an incoming photon from the illumination source and a vector in the direction of an outgoing photon to the observing instrument. If illumination is from behind the instrument, phase_angle will be small. | |||
