Validation of MISR land surface broadband albedo

open access: yesInternational Journal of Remote Sensing, 2008
Land 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

open access: yesClimatic Change, 2002
Land 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

The variation analysis of land surface albedo in Beijing in recent ten years

open access: yes2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The surface land albedo is an important parameter of the energy balance. It is very significant for the urban micro-climate and environment to research the variation and analysis of land surface albedo. In this paper, the variation of land surface albedo in Beijing in recent ten years, the correlation of the albedo and underlying surface type, the ...

An Improved Method For Retrieving Land Surface Albedo Over Rugged Terrain

open access: yesIEEE Geoscience and Remote Sensing Letters, 2014
Land 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 ...

Parameterization of land surface albedo

Chinese Optics Letters, 2014
Remote 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 ...

The retrieval of land surface albedo in rugged terrain

2012 Second International Workshop on Earth Observation and Remote Sensing Applications, 2012
Land surface albedo may be derived from the satellite data through the estimation of a bidirectional reflectance distribution function (BRDF) model and angular integration. However many BRDF models do not consider explicitly the topography. In rugged terrain, the topography influences the observed surface reflectance, and varies the distribution of ...

An Improved Land-Surface Albedo Algorithm With DEM in Rugged Terrain

IEEE Geoscience and Remote Sensing Letters, 2014
The 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.

VIIRS land surface albedo product: Algorithm development and validation

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Visible 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 ...
