Abstract :
Sun glint obscures the radiance originating from within the water, but it also mirrors the solar radiance after transmission through the atmosphere. The difference between a glint-contaminated pixel and a nearby nonglint pixel from a spectral image prior to atmospheric correction yields a direct estimate of the spectral transmission of solar radiance which can then be used both to confirm atmospheric models and to retrieve an estimate of remote sensing reflectance
