100 Cities Project
The 100 Cities Project uses satellite remote sensing data collected over cities worldwide to
monitor socioeconomic and biogeographic variables. ASTER is the primary source of data for this
NASA funded project housed at the Center for Environmental Science Applications (CESA) at
Arizona State University (ASU).

ASTER Global Emissivity Database (ASTER GED, previously NAALSED)
The ASTER Global Emissivity Database (ASTER GED) is a mean, gridded, Land Surface Temperature and Emissivity (LST&E) climatology dataset calculated using all clear-sky pixels for a given location from all ASTER scenes acquired from 2000-2008. Initially released as a seasonal North American ASTER Land Surface Emissivity Database (NAALSED) v3, ASTER-GED is calculated as a mean of all available data over regions of Africa, Australia, and Eurasia. Remaining areas of the globe including South America and an updated North America will be completed by end of 2014. The ASTER GED is output on 1 degree x 1 degree grids at 100-m, and 1-km resolution, and products include the mean emissivity and standard deviation for all 5 ASTER TIR bands, mean LST and standard deviation, a re-sampled ASTER GDEM, land-water mask, mean NDVI and standard deviation, latitude, longitude, and observation count. ASTER GED LST&E are retrieved using the ASTER-TES algorithm in combination with the Water Vapor Scaling (WVS) atmospheric correction method with MOD07 profiles and the MODTRAN 5.2 radiative transfer model.
