研究目的
To discuss the utility of and strategies for using the Moon to calibrate satellite remote sensing measurements.
研究成果
Further development of the Moon as a radiometric calibration standard will benefit future programs while adding value to present and past data sets containing lunar views. Specifically, an SI-traceable calibration of lunar spectral irradiance at reflected solar wavelengths with an uncertainty of 1 % and continuous spectral coverage, combined with a model such as the USGS model mentioned above, would meet the needs of many existing and planned programs, and is achievable with a series of ground- and space-based measurements.
研究不足
The Moon does not cover the full dynamic range of Earth scenes captured by satellite sensors. Reflected light from the Moon is slightly polarized. Solar variability will affect the most precise measurements, especially at short wavelengths. Usability depends on phase angle. Many missions need to calibrate more often than is either practical or possible to view the Moon.
