Paper Abstract

A spectral model of downwelling and upwelling irradiance reflectance from and transmittance through a wind-ruffled sea surface is developed. Dependences for sea surface slope distribution based on Cox and Munk (1954) and the foam coverage of the sea surface based on Gordon and Jacobs (1977), both these distributions having been modified by the author, were used in modelling. Being direct functions of a dynamic factor, i.e. mean height of wind waves, they take the influence of environmental (hydrometeorological and geometrical) factors into account. Snell and Fresnel laws were applied to the light transmission through the surface. Spectral dependences of light refraction in the 350 - 18,000 nm range were taken into account. Polarization effects were neglected. On the basis of this model, a simplified polynomial method for calculating the real surface reflectance and transmittance of downwelling and upwelling irradiance is presented.
