Emissivity DatabaseEntry ID: naalsed Abstract: The North
American Advanced Spaceborne Thermal Emission and Reflection
radiometer (ASTER) Land Surface Emissivity Database (NAALSED)
covers the continent with 3,327 1 degree (°) x 1° tiles of
100-meter (m) resolution data. The data are placed in geographic
coordinates (latitude, longitude) and distributed as
Hierarchical Data Format Version 5 (HDF5) files. Each NAALSED
product contains several ... layers of related data such as
Emissivity, Temperature, and a top of atmosphere Normalized
Difference Vegetation Index (NDVI). Additional supporting layers
include a regional version of the ASTER Global Digital Elevation
Model (GDEM) V001 resampled to 100-m, a land water map, pixel
geographic coordinates, and the number of observations used as
input. The NAALSED parameters are averaged for every clear-sky
pixel available in the ASTER mission record from 2000 through
2010. A New ASTER Cloud Mask Algorithm (N
