- Measurements were made between 350nm and 2500nm with a spectral sampling of 1.4 nm @ 350-1 000 nm and 1.1 nm @ 1 001-2 500 nm. data were then automatically interpolated and resampled with a 1nm interval during export by the fieldspec software
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).
