Spectrum type

Experiment type: laboratory measurement
Type: reflectance factor
Comments: In the reduced data set, absolute uncertainty on the calibrated reflectance factor is ±0.1, and the spatial variability of the reflectance across the field of view is of the order of 10%. Thus, the SCITEAS imaging system does not provide a very accurate measurement of the absolute reflectance, but it provides a spectrum resolved in wavelength from 0.4 to 2.4 μm.

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: biconical
Observation mode: fixed angles
Emergence angle: 13.0°
Azimuth angle: 0.0°

Comments: The light beam emitted from the extremity of the fibre bundle positionned about 300 mm above the sample surface has a divergence half-angle of 12.7°. The light source incidence and azimuth angles are slightly variable from pixel to pixel.

Spatial parameters

Observation mode: roi averaged
Comments: Note to the provider: Complete the "image" observation_mode when fully implemented in SSHADE. Because SCITEAS data are hyperspectral images.
