Angular parameters

Definition: incidence and emergence angles are positive with origin at nadir, and vary in same direction. Azimuth origin (increasing clockwise) is for i = e (opposition geometry).

Observation geometry: bidirectional
Observation mode: fixed angles
Incidence angle: 45.0°
Resolution illumination: 0.5°
Resolution observation: 25.0°
