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

2012 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 ...

Method for calculating land surface broadband albedo

Aerospace Engineering and Technology
A method for calculating the broadband albedo of the Earth’s surface is proposed, which is used on the basis of two narrowband albedos calculated using signals from two AVHRR channels. It has been established that the Liang formula used to calculate the broadband albedo does not allow for the presence of an arbitrary functional relationship between the

Direct Estimation of Land Surface Albedo From Simultaneous MISR Data

IEEE Transactions on Geoscience and Remote Sensing, 2017
The availability of multiangular information from the NASA Multi-angle Imaging SpectroRadiometer (MISR) instrument provides an excellent opportunity for the characterization of surface anisotropy, which can be used for improving surface albedo estimation. However, the MISR data have been reported with large uncertainties and data gaps due to inaccurate

Can flowers affect land surface albedo and soil microclimates?

International Journal of Biometeorology, 2021
The phenology of vegetation, namely leaf-out and senescence, can influence the Earth's climate over regional spatial scales and long time periods (e.g., over 30 years or more), in addition to microclimates over local spatial scales and shorter time periods (weeks to months). However, the effects of flowers on climate and microclimate are unknown.

Land surface albedo from Meteosat Second Generation (MSG) observations

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
In the framework of the EUMETSAT Satellite Application Facility for land surface analysis (Land-SAF) we develop a surface albedo product which is generated from observations provided by the SEVIRI instrument on board of the geostationary MSG satellite.

Validation of Global Land Surface Satellite Phase-2 Surface Broadband Albedo Product

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Surface broadband albedo is a critical parameter in surface radiation budget (SRB), which controls the input, separation, and allocation of the Earth's surface energy. Recently, a Global LAnd Surface Satellite (GLASS) phase-2 surface broadband albedo product has been generated from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the ...

Manifestation of land surface albedo and temperature dynamics towards land cover.

2022
Land 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), 2001
An 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, 1993
The 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

1983
Publisher 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 ...
