NASA Distributed Active Archive Centers (DAACs)
The purpose of the NASA-funded system of distributed active archives is to provide consistent and stable scientific data stewardship for NASA Earth Observation System data. There are currently nine data centers in the system covering the range of Earth science and related data. More information about the DAACs, their data, and their activities may be found at the NASA DAAC Web site: http://nasadaacs.eos.nasa.gov/.

The DAAC system includes:

Alaska Satellite Facility (ASF) DAAC

Synthetic Aperture Radar (SAR), sea ice, polar processes, geophysics
