An Improved Land-Surface Albedo Algorithm With DEM in Rugged Terrain
IEEE Geoscience and Remote Sensing Letters, 2014The influence of topography on land-surface bidirectional reflectance and albedo should be considered in rugged terrain. However, land-surface albedo algorithms neglect topographic effects, leading to errors in estimating the albedo in rugged terrain.

Validation of MISR land surface broadband albedo
International Journal of Remote Sensing, 2008Land surface broadband albedo is a critical variable for many scientific applications. Due to the scarcity of spectral albedo measurements of the Earth's surface environments, it is useful to construct broadband albedo from spectral albedo data obtained by multi-angle satellite observations. The Multi-angle Imaging SpectroRadiometer (MISR) onboard NASA'

Land Cover, Rainfall and Land-Surface Albedo in West Africa
Climatic Change, 2002Land surface albedo is an important variable in General Circulation Models (GCMs). When land cover is modified through anthropogenic land use, changes in land-surface albedo may produce atmospheric subsidence and reduction of rainfall. In this study we examined albedo time series and their relationships with rainfall, land cover, and population in West

VIIRS land surface albedo product: Algorithm development and validation
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017Visible Infrared Imaging Radiometer Suite (VIIRS) land surface albedo (LSA) product is one of the routinely generated VIIRS environmental data records (EDR). A direct estimation approach based on radiative transfer simulation was developed to directly estimate instantaneous LSA value from VIIRS clear-sky top-of-atmosphere (TOA) reflectance ...

Global land‐surface albedo modelling
International Journal of Climatology, 1993AbstractThe climatic impact of changes in terrestrial albedo has been studied using numerous climate models, ranging from simple, one‐dimensional energy balance climate models to the most complex, three‐dimensional general circulation models of the atmosphere.

Comparison of MISR and MODIS land surface albedos: Methodology
Journal of Geophysical Research: Atmospheres, 2010The broadband white sky surface albedo (bihemispherical reflectance) products available from the Moderate Resolution Imaging Spectroradiometer (MODIS) are compared at regional and continental scales with similar products generated from the Multiangle Imaging Spectroradiometer (MISR) land surface bidirectional reflectance factor (BRF) parameters.

NOAA AVHRR land surface albedo algorithm development
International Journal of Remote Sensing, 1997Abstract The primary objective of this research is to develop a surface albedo model for the National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR). The primary test site is the Konza prairie, Kansas (U.S.A.), used by the International Satellite Land Surface Climatology Project (ISLSCP) in the First ...

Atmospheric and geometrical effects on land surface albedo
Journal of Geophysical Research: Atmospheres, 1999In spite of extensive experimental and theoretical studies of land surface albedo, there is a need of generalization and systematic quantification of its dependence on solar zenith angle and type of surface, and of atmospheric effects in these relationships.

Downscaling of Land Surface Albedo Method Based on Stratified Linear Regression
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018Due to limitation of observation angles and resolution of satellite sensor, the resolution of surface albedo products retrieved based on angle information is usually coarse, such as MODIS albedo products and GLASS albedo products. Downscaling method of stratified linear regression proposed in this study solved this problem.

An Improved Method For Retrieving Land Surface Albedo Over Rugged Terrain
IEEE Geoscience and Remote Sensing Letters, 2014Land surface albedo is a very important parameter, which can be derived from a bidirectional reflectance distribution function (BRDF) model with angular integration of BRDF in a particular distribution of downward solar irradiance. The Algorithm for MODIS Bidirectional Reflectance Anisotropic of Land Surface (AMBRALS) utilizes a kernel-driven BRDF ...
