Emissivity and Reflectance of Model Sea Surface for the Use of AVHRR Data of NOAA Satellites

Abstract

   The ocean surface is simulated by many facets whose slopes are according to the isotropic and anisotropic Gaussian distribution with respect to surface wind. The slope of the facets depends upon the ocean surface wind (Cox and Munk, 1955). The reflection characteristics of the surface are expressed by the incident and emergent directions of radiation. The discussions are applied to the investigations of the ocean surface characteristics as well as to the atmospheric aerosols by the use of the AVHRR data on board the NOAA-6 satellites (visible, 3.7μm and 11μm window regions).
   The reflectance (or emissivity) of the model surface in the case of the isotropic Gaussian distribution of slopes are tabulated as a function of surface wind.
