Paper Abstract

The Moon has been shown to be an extremely stable radiometric reference for calibration and long-term stability measurements of on-orbit sensors. The majority of previous work has been in the visible part of the spectrum, using ground-based lunar images. The SOLar-STellar Irradiance Comparison Experiment (SOLSTICE) on the SOlar Radiation and Climate Experiment (SORCE) can be used to extend the lunar spectral irradiance dataset to include the 115-300 nm range. SOLSTICE can directly measure both the solar and lunar spectra from orbit, using the same optics and detectors. An observing campaign to map out the dependence on phase angle began in mid 2006, and continues through the present. The geometry of SORCE's orbit is very favorable for lunar observations, and we have measurements of almost the entire 0-180 degree range of phases. In addition to Earth Observing Systems using the Moon for calibration, recent planetary missions have also made ultraviolet observations of the Moon during Earth flyby, and these SOLSTICE measurements can be useful in calibrating their absolute responsivity.
