Retrieval of Surface Albedo Based on BRDF Model
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018Land 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, 1991Recent 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
2010Results 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 ...

Aircraft Measurements of Albedo and Absorption of Stratus Clouds, and Surface Albedos
Journal of Applied Meteorology, 1968Abstract 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, 1974Photoelectric 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 ...

Surface Roughness Effects on Soil Albedo
Soil Science Society of America Journal, 2000Knowledge of how surface roughness influences the reflectance of sunlight from cultivated soils is useful in various applications, such as estimating albedo values used as inputs to soil temperature models and erosion models. The albedos of two soils were studied for dry and wet surfaces with four different roughness conditions, changed from a ...

Quarterly Journal of the Royal Meteorological Society, 1984
AbstractA simple method for the calculation of the net shortwave flux at the surface for overcast situations is presented. Explicit account is taken of the effect of cloud optical thickness and multiple reflections between the surface and cloud base. Using simple two‐stream theory, a theoretical form for the flux is proposed, and then results from a ...

Determination of surface albedo from satellites
Advances in Space Research, 1985Abstract The dynamical features of the climate system result from the interaction of the atmosphere with the surface. The hope for improving climate prediction, on seasonal and interannual time scales, is based on the premise that slowly varying boundary conditions force well defined predictable patterns of general circulation.

Some observations from aircraft of surface albedo and the albedo and absorption of cloud
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1958The albedo of sea and land surfaces, and the albedo and absorption of persistent layers of cloud, for solar radiation, have been measured from an aircraft fitted with upward- and downward-facing pyranometers. The lowest, mean, and highest values measured, espressed as fractions of the incident radiation, are
