SOLAR UVB‐ALBEDO OF VARIOUS SURFACES
Photochemistry and Photobiology, 1988Abstract— Measurements of the albedo of various surfaces in open grounds show significant differences for solar UVB radiation and total solar radiation (0.3–3μm). Above grassland, that albedo for solar UVB radiation is significantly smaller than that for total solar radiation (UVB: 1.3%, total: 20.7%); contrary to that, the albedo for UVB radiation is ...

Parameterization of land surface albedo
Chinese Optics Letters, 2014Remote measurements of Earth's surface from ground, airborne, and spaceborne instruments show that its albedo is highly variable and is sensitive to solar zenith angle (SZA) and atmospheric opacity. Using a validated radiative transfer calculating toolbox, DISORT and a bidirectional reflectance distribution function library, AMBRALS, a land surface ...

Albedo distribution on Io's surface
Icarus, 1979A visual albedo distribution model for all hemispheres of Io's surface has been synthesized from available earth-based and spacecraft image and photometric data. The resulting model indicates some interesting patterns and symmetries on Io's surface: the dark polar caps are shifted off Io's rotational axis and are elliptical rather than circular in ...

Annual Cycle of Surface Albedo
Monthly Weather Review, 1980Abstract Monthly mean surface albedo for the full spectra range of incoming solar radiation and average atmospheric properties is estimated for the period 1 April 1974–31 March 1975. It can be considered approximately representative of average conditions in the last decade.

Surface albedo from bidirectional reflectance
Remote Sensing of Environment, 1991The validity of integrating over discrete wavelength bands is examined to estimate total shortwave bidirectional reflectance of vegetated and bare soil surfaces. Methods for estimating albedo from multiple angle, discrete wavelength band radiometer measurements are studied.

Consideration of land use change-induced surface albedo effects in life-cycle analysis of biofuels
Energy and Environmental Science, 2016 Land use change (LUC)-induced surface albedo effects for expansive biofuel production need to be quantified for improved understanding of biofuel climate impacts. We addressed this emerging issue for expansive biofuel production in the United States (U.S.

Abstract We have shown in the past that the radiative-convective energy balance atmospheric model used at the General Motors Research Laboratories in our atmospheric physics research is extremely sensitive to the input value of surface albedo used. In response to this we developed a new global model of the surface albedo based on a detailed analysis of

Surface albedo of cometary nucleus
Advances in Space Research, 1989Abstract Direct images of the nucleus of comet Halley have revealed an extremely structured and dark surface. This low albedo arises from, at least, two plausible possibilities, i.e. (1) absorption of incident light by non-volatile crust of dark material, and (2) multiple reflection of incident light due to the roughness of the nucleus surface, with ...

Spectral albedo of natural surfaces
pure and applied geophysics, 1964The short description of the field distance installation for measuring spectral albedo as relation of semi-spherical fluxes of reflected and incoming radiation is made. Data on the measurements of spectral albedo in the wavelength range from 450 to 950 mμ for different natural surfaces are given.

Abstract An experimental study of the albedo of the sea surface for shortwave solar radiation has been carried out on a fixed platform. Fifteen-minute totals of upward and downward irradiances were recorded continuously for four months over a wide range of atmospheric and sea conditions.
