The interband calibration is the transfer of the absolute calibration from one or two wavelengths to the other spectral bands. This is done by adjusting the spectral reflectances observed over some natural targets, which present spectrally flat reflectances in the solar spectrum, to the calibrated reflectance for the same target. Cloud and the ocean sunglint are such bodies. The two phenomena are very frequent in satellite imagery and are certainly good candidates for an operational procedure. This paper describes two approaches, which are applied to the PolDER “Polarization and Directionality of Earth's Reflectances” spectral bands using these targets.
