The surface Albedo distribution of Pluto

Icarus, 1989
Two distinct configurations have been established for the surface albedo distribution of Pluto on the basis of a model fitting absolute photometry data obtained over the 1954-1986 period. The two sets of model parameters primarily differ in the equatorial spots; these generate the rotational lightcurve, while the polar caps yield the orbital lightcurve.

Spectral albedo of natural surfaces

pure and applied geophysics, 1964
The 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.

Surface albedo of cometary nucleus

Advances in Space Research, 1989
Abstract 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 ...

Aircraft Measurements of Albedo and Absorption of Stratus Clouds, and Surface Albedos

Journal of Applied Meteorology, 1968
Abstract Aircraft measurements of the albedo of stratus clouds were made, with the results suggesting, on occasion, that the liquid water content of the cloud has a stronger influence than the cloud thickness on the albedo. The mean cloud absorption was found to be 4% of the incident downward flux.

Albedo variations on the surface of mercury

Planetary and Space Science, 1974
Photoelectric photometric (slit) scans of Mercury have been obtained and combined with a man of the surface markings to yield relative normal albedoes over about one quarter of the planet's total surface at a wavelength of 0·45 microns. Maximum albedo ratios at a resolution of one fifth of the planetary diameter are not less than 2 to 1 and probably ...

Retrieval of Surface Albedo Based on BRDF Model

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Land Surface Albedo is an important surface parameter and is widely applied to the surface energy balance, mid-term and long-term weather forecast and atmospheric general circulation model. GF-4 satellite is the first geostationary orbit satellite which combines high spatial resolution and high temporal resolution in China.

Tropical Deforestation: Albedo and the Surface-Energy Balance

Climatic Change, 1991
Recent micrometeorological measurements for Amazonian rainforest are reviewed, emphasising those aspects of the radiation and heat balance which are likely to change with deforestation. The possible consequences of such deforestation are considered by examining the sensitivity of the surface energy balance to changes in those parameters which would be ...

Variability of Surface Temperature and Albedo

2010
Results from the analysis of the spatial and temporal variability of surface temperature, including that of liquid water at high latitudes, are presented using mainly NOAA/AVHRR data from 1981 to 2008. The average surface temperature of the region north of the Arctic Circle is shown to be increasing at 0.7°C/decade while that south of the Antarctic ...

Albedos of natural surfaces in Barbados

Quarterly Journal of the Royal Meteorological Society, 1967
AbstractIn Barbados, albedo values for bare soil surfaces varied according to colour, the moisture condition of the surface layer, the presence of limestone concretions and the roughness of the surface. The albedo of sugar cane increased with crop height until the leaves reached complete cover.

Diurnal asymmetry in surface albedo

Agricultural and Forest Meteorology, 1998
Observed surface albedos do not always exhibit the classical diurnal symmetry associated with the diurnal variation of zenith angle. Morning/afternoon albedo differences observed in even vegetated terrain are found to range on the daily average from 0.01 to 0.05 in magnitude in this study, and they have been found to be as high as 0.1 at a given solar ...
