Removing air/water interface effects from hyperspectral radiometry data

Close range hyperspectral remote sensing is an important tool for cal/val of satellite and airborne remote sensing data. However, automated systems on jetties, ships of opportunity, and buoys are nowadays more frequently used also as remote sensing measurements in their own right. One of the problems in interpreting the data collected during automated measurements is removing sun and sky glint from the reflectance spectra. Current methods for removal of the surface effects have not been very successful. We developed a method that uses reflectance measured in both ends of the spectrum (350-380 nm and 890-900 nm) to estimate the contribution of sun and sky glint in the measured signal and retrieve signal free from the water surface effects.
