Retrieval of Spectral Reflectance of High Resolution

A white Barium Sulfate (BaSO4) panel is used for reflectance calibration and in situ irradiance measurements. The spatial resolution of the imagery is 25 cm; the radiometric resolution is 8-bit. The raw images are mosaicked and orthorectified and the model converts their digital numbers (DN) to reflectance values.

Pre-Mix White Reflectance Coating Edmund Optics

The Pre-Mix White Reflectance Coating is a water based barium sulfate coating formulated to yield paint with high diffuse reflectance of ultraviolet, visible, and near-infrared wavelengths. The pre-mix coating is available in 250ml and 500ml bottles and requires mixing at approximately a 10.50.3 ratio of pre-mix to pure ethanol to distilled water, prior to use.
