MODIS Derived 1.24 micron white-sky albedo on a global, 1-minute equal angle grid

Version 1 eng
  • Abstract
    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 Micrometer , 0.55 Micrometer, 0.67 Micrometer, 0.86 Micrometer, 1.24Micrometer, 2.1 Micrometer, 0.3-0.7 Micrometer, 0.3-5.0Micrometer, and 0.7-5.0Micrometer) 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.
