New algorithm of correction on sun glint for satellite ocean color scanner MODIS is developed. It is
built on MODIS data only, without ancillary information on wind speed. The approach is based on a
retrieval of the nonselective factor associated with the surface slope distribution by using data from three
MODIS infrared bands including 1240 nm. This nonselective factor depends only on wind speed and
viewing geometry, whereas other parameters of ocean-atmosphere system are spectrally dependent. As
an example, the obtained results for the Caspian Sea and the Atlantic Ocean are demonstrated.
