Item Airborne Lunar Spectral Irradiance (air-LUSI) Missioni Capability Demonstration(Calcon, 2020-09-21) Turpie, Kevin; Brown, Steve; Woodward, John; Gadsden, Andrew; Stone, Tom; Grantham, Steve; Maxwell, Stephen; Larason, Tom; Newton, Andrew; Rice, JoeThe Moon is a very useful calibration target for Earth-observing sensors in orbit because its surface is radiometrically stable and it has a radiant flux comparable to Earth scenes. To predict the lunar irradiance given an illumination and viewing geometry, the United States Geological Survey (USGS) has developed the Robotic Lunar Observatory (ROLO) Model of exo-atmospheric lunar spectral irradiance. The USGS ROLO model represents the current most precise knowledge of lunar spectral irradiance and is used frequently as a relative calibration standard by space-borne Earth-observing sensors. However, instrument calibration teams have expressed the need for an absolute lunar reference with higher accuracy.
