• North American ASTER Land Surface Emissivity Database (NAALSED)
  NAALSED is a collection of 3,327 1 degree by 1 degree tiles compiled from all clear ASTER "leaf on" season (July, August, September) data collected over North America from 2000 to 2010. Each tile contains several layers of science data sets, including surface emissivity, temperature, and a top of atmosphere Normalized Difference Vegetation Index (NDVI). Each tile also contains supplemental layers, such as a regional version of the ASTER GDEM resampled to 100 meters, geographic coordinates, a land-water map, and the number of observations used as input. NAALSED tiles are available to registered users at no cost, and may be downloaded from NASA Reverb, LP DAAC Data Pool, and USGS Earth Explorer.
