RISA New Look at the Discrete Ordinate Method for Radiative Transfer Calculations in Anisotropically Scattering Atmospheres. II: Intensity Computations
Publisher: American Meteorological Society
Abstract: The recently developed matrix method to solve the discrete ordinate approximation to the radiative transfer equation in plane parallel geometry (Stamnes and Swanson, 1981) is extended to compute the full azimuthal dependence ...
A New Look at the Discrete Ordinate Method for Radiative Transfer Calculations in Anisotropically Scattering Atmospheres
Publisher: American Meteorological Society
Abstract: The difficulties inherent in the conventional numerical implementation of the discrete ordinate method (following Chandrasekhar's prescription) for solving the radiative transfer equation are discussed. A matrix formulation ...
Radiative Energy Budget in the Cloudy and Hazy Arctic
Publisher: American Meteorological Society
Abstract: A radiation model is constructed that includes radiative interactions with atmospheric gases as well as parameterized treatments of scattering and absorption/emission by cloud droplets and haze particles. A unified treatment ...
Surface Albedo over the Arctic Ocean Derived from AVHRR and Its Validation with SHEBA Data
Publisher: American Meteorological Society
Abstract: A method is presented for retrieving the broadband albedo over the Arctic Ocean using advanced very high resolution radiometer (AVHRR) data obtained from NOAA polar-orbiting satellites. Visible and near-infrared albedos ...
A Critical Examination of Satellite Cloud Retrieval from AVHRR in the Arctic Using SHEBA Data
Publisher: American Meteorological Society
Abstract: This study examines the validity and limitations associated with retrieval of cloud optical depth τ and effective droplet size re in the Arctic from Advanced Very High Resolution Radiometer (AVHRR) channels 2 (0.725?1.10 ...
Light Reflection from Water Waves: Suitable Setup for a Polarimetric Investigation under Controlled Laboratory Conditions
Publisher: American Meteorological Society
Abstract: The reflection of sunlight from a wavy water surface, often referred to as sun glint, is a well-known phenomenon that presents challenges but also hitherto untapped opportunities in remote sensing based on satellite imagery. ...
Water Surface Topography Retrieved from Color Images
Publisher: American Meteorological Society
Abstract: ubmerged objects viewed through wavy water surfaces appear distorted by refraction. An imaging system exploiting this effect is implemented using a submerged planar light source designed so that color images reveal features ...
New Treatment of Strongly Anisotropic Scattering Phase Functions: The Delta-M+ Method
Publisher: American Meteorological Society
Abstract: AbstractThe treatment of strongly anisotropic scattering phase functions is still a challenge for accurate radiance computations. The new delta-M+ method resolves this problem by introducing a reliable, fast, accurate, and ...
