研究目的
To examine the relationship between the Earth scene stray light and the signals in VIIRS’s calibrators to better understand stray light characteristics and to improve upon the current correction method.
研究成果
The analysis of calibration view data indicated that it can be used to improve Earth view stray light characterization and correction. The study demonstrated the potential of using calibration view data to track stray light onset angles, refine current stray light correction, and identify additional stray light features. Further refinement in characterization and correction is important for ensuring VIIRS DNB imagery quality for Soumi NPP and future missions.
研究不足
The study acknowledges uncertainties in stray light estimation due to imperfect dark surface selection and airglow approximation. The current method cannot resolve an additional stray light feature in the southern hemisphere during its springtime without modification.
