Product Description -------------------

              The Filled Land Surface Albedo Product is a global data
              set of spatially complete albedo maps. It was derived from
              the MODIS MOD43B3 Land product and includes both white-sky
              and Black Sky conditions. With each sky condition, there
              are 10 wavelengths (0.47 ??m, 0.55 ??m, 0.67 ??m, 0.86 ??m,
              1.24 ??m, 2.1 ??m, 0.3-0.7 ??m, 0.3-5.0 ??m, and 0.7-5.0 ??m)
              and 23 sixteen-day periods per year (001, 017,
              ... 353). There are two types of Filled Land Surface
              Albedo Products: 1-minute Map Products and coarser
              resolution Statistical Products.

              Map products contain spatially complete land surface albedo data and
              are generated at 1-minute resolution on an equal-angle grid. Quality
              Assurance (QA) features are built into each Map product at same
              1-minute resolution as the albedo data. Maps are stored in separate
              HDF files for each albedo type (white- and black-sky), wavelength, and
              16-day period.

              Research and Application
              The availability of global land surface characteristics and albedo
              data over a wide range of spectral bands and at high spatial
              resolution has dramatically improved with the launch of the MODIS
              instrument aboard NASA's Earth Observing System (EOS)
              spacecraft. However, lack of spatial and temporal coverage due to
              cloud and snow effects can preclude utilization of official products
              in production and research studies.

              The Filled Land Surface Albedo Product has been developed by employing
              phenological temporal curve fitting to statistically fill missing data
              in the official MOD43B3 product in order to provide spatially complete
              global maps.  Additionally, statistics of the complete albedo maps at
              various resolutions, an ecosystem classification, as well as a
              Normalized Difference Vegetation Index (NDVI) product computed from
              the complete albedo maps, are provided.

              Spectral land surface albedo is an important parameter for describing
              the radiative properties of the Earth while the ecosystem
              classification and NDVI products are important parameters in
              describing the productivity and characteristics of the land
              surfaces. These products reflect the consequences of natural and human
              interactions, such as anthropogenic, meteorological, and phenological
              effects on local and global climatological trends. Consequently, these
              products are integral parts in a variety of research areas, such as
              general circulation models (GCMs), energy balance studies, modeling of
              land use and land use change, as well as biophysical, oceanographic,
              and meteorological studies.
