Manifestation of land surface albedo and temperature dynamics towards land cover.
2022Land surface albedo studies have always been dominated by the snow-covered area while snow-free area albedo effects induced by the land use and land covers are much less documented. The objective of this study is to investigate the significant differences of land surface albedo (LSA) and land surface temperature (LST) across the multiple types of land ...

Exploitation of surface albedo derived from the Meteosat data to characterize land surface changes
IGARSS 2001. Scanning the Present and Resolving the Future. Proceedings. IEEE 2001 International Geoscience and Remote Sensing Symposium (Cat. No.01CH37217), 2001An advanced algorithm to characterize land surface properties on the basis of Meteosat-5 data has been developed and applied to year 1996 observations. Surface albedo values decontaminated from atmospheric effects and computed for a fixed Sun location have been derived for every day of 1996.

Incorporating landscape heterogeneity in land surface albedo models
Journal of Geophysical Research: Atmospheres, 1993The importance of incorporating landscape heterogeneity into climate models has been recognized by a number of researchers. However, attempts to relax the assumption of uniform, homogeneous and complete vegetation cover have generally been limited to modeling each component of the landscape (e.g., trees, grasses, shrubs) as a homogeneous unit and then ...

Land Surface Processes and Climate—Surface Albedos and Energy Balance
1983Publisher Summary This chapter provides an overview of land surface processes and climate-surface albedos, and attempts to bridge the gap between disciplinary studies of atmospheric versus surface climate. The chapter describes physical processes involving the land surface that are of concern to scientists interested in modeling the global climate ...

An improved method for accurate calculation of albedos of inhomogeneous land surfaces
International Journal of Remote Sensing, 1994Abstract A model for computing the albedos and BRDF (bidirectional reflectance distribution function) of inhomogeneous land surfaces consisting of two different components has been developed. An empirical equation, based on the model results, for calculating albedos of inhomogeneous land surfaces and avoiding errors caused by shadowing effect was set ...

Temporal Analysis of Remotely Sensed Land Surface Shortwave Albedo
2016Satellite-derived surface albedo products have offered great opportunities in monitoring surface energy budget. However, existing satellite albedo products may have suffered from data gaps and/or inconsistency caused by cloud contamination, sensor difference, and retrieval algorithm failure, which will lead to the limitations in long-term time series ...

AbstractDaily mean albedo, a crucial variable of the earth radiation budget, is significantly affected by the diurnal variation of land surface albedo (DVLSA). The DVLSA typically exhibits asymmetry, thereby affecting the estimation of the daily mean albedo. However, the asymmetry in the DVLSA is generally ignored in daily mean albedo estimation.

The Albedo of Vegetated Land Surfaces: Systems Analysisand Mathematical Modeling
Theoretical and Applied Climatology, 1998The albedo of vegetated land surfaces (surface albedo) is a key factor in climate modeling and in mechanistic accounting of many ecological processes. This paper proposes a testable numerical equation for the analysis and projection of surface albedo. Conceptualized as the manifestation of a canopy elements-determined basic property after modifications

MODELING LAND-SURFACE ALBEDOS FROM VEGETATION CANOPY ARCHITECTURE
Physical Geography, 1991Over the past decade, the 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 more sophisticated, three-dimensional general circulation models of the atmosphere.
