Effects of Implementing MODIS Land Cover and Albedo in MM5 at Two Contrasting U.S. Regions

MODIS Land Cover Product Algorithm Theoretical Basis Document (ATBD) Version 5.0 MODIS Land Cover and Land-Cover Change

This document details the structural definition, development process, and functional flow of the MODIS Land-Cover Product. The Land Cover and Land-Cover Change Parameters were proposed by the MODIS Land Team, with Team Member Alan Strahler leading the effort. The Land Cover Parameter is a 1-km product provided on a quarterly basis beginning about one year following the acquisition of a global d...

Linear unmixing of MODIS albedo composites to infer subpixel land cover type albedos

We use a linear unmixing approach to test how land use and forestry maps, in combination with the MODIS BRDF/albedo product, can be used to estimate land cover type albedos in boreal regions. Operational land use maps from three test areas in Finland and Canada were used to test the method. The resulting endmember albedo estimates had low standard errors of the mean and were realistic for the m...

Impact 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...

A comparative analysis of the Global Land Cover 2000 and MODIS land cover data sets

Accurate and up-to-date global land cover data sets are necessary for various global change research studies including climate change, biodiversity conservation, ecosystem assessment, and environmental modeling. In recent years, substantial advancement has been achieved in generating such data products. Yet, we are far from producing geospatially consistent high-quality data at an operational l...
