The impact on the reflectance in VIS of a type of crude oil film floating on the water surface.
This paper reports the reflective features of a water surface covered with an oil film expressed by the dependence of the reflectance on the angle of light incidence and wavelength a nd film thickness with respect to downward and upward light fluxes. The sensitivity of the shape of these functions on the oil type appears especially strong in case of the upward light fluxes as opposed to downward fluxes.
