Description:
The spectral and broadband reflectance of naturally occurring desert sand, black lava, gypsum sand, and snow cover is measured from a twin engine Cessna 402-series aircraft. The measurement system is computer controlled and electrically isolated from the aircraft. It consists of upward and downward looking hemispheric diffusers, filters, a rotating 90 degree mirror, a focusing lens, and a double monochromator/PMT or a UV enhanced photodiode. Measurements are made at several altitudes enabling the empirical determination of the backscatter and attenuation effects on the reflectance. These reflectance results along with those reported earlier for a pine forest, green farmland, the open ocean, and brown farmland are represented analytically.
