Estimating Land Surface Albedo from Satellite Data
Title: ESTIMATING LAND SURFACE ALBEDO FROM SATELLITE DATA Tao He, Doctor of Philosophy, 2012 Directed by: Dr. Shunlin Liang, Professor Department of Geographical Sciences Land surface albedo, defined as the ratio of the surface reflected incoming and outgoing solar radiation, is one of the key geophysical variables controlling the surface radiation budget. Surface shortwave albedo is widely use...
متن کاملEstimating Daily Land Surface Temperatures in Mountainous Environments by Reconstructed MODIS LST Data
Continuous monitoring of extreme environments, such as the European Alps, is hampered by the sparse and/or irregular distribution of meteorological stations, the difficulties in performing ground surveys and the complexity of interpolating existing station data. Remotely sensed Land Surface Temperature (LST) is therefore of major interest for a variety of environmental and ecological applicatio...
متن کاملImpact of MODIS BRDF and Albedo on Land Surface Models
Land surface albedo describes the fraction of incoming solar energy reflected at a given point and time, and hence determines the surface temperature and evapotranspiration. It is strongly dependent on the solar zenith angle and the three-dimensional structure of vegetation canopy (e.g., Yang et al. 2001; Schaaf et al. 2002). The land surface albedo in regional and global models can be specifie...
متن کاملEstimation of land surface albedo time series and trends based on MODIS data
The land surface albedo is among the most important parameters controlling the atmospheric radiation fluxes and the surface–atmosphere interactions. In the present study, surface albedo parameters and aerosol optical thickness (AOT) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor, onboard NASA’s Terra and Aqua satellites, were analyzed and processed for the estimation...
متن کاملRetrieval of Land Surface Reflectance and Albedo from Meris Data
An atmospheric correction algorithm for the retrieval of land surface reflectance from the Medium Resolution Imaging Spectrometer (MERIS) data has been implemented. The algorithm is designed to obtain the main atmospheric parameters needed in the correction from the image itself, leading to an optimal characterization of the atmospheric state, in temporal and spatial resolution terms. The first...
