EOS Data GatewayEOS Data Gateway
EDG provides:– Web based interface for data search and order– Access to data handling tools and services
from Earth science data archives
EDG interfaces with:– The nine data centers of the Distributed Active
Archive Center (DAAC) Alliance– Co-operating International Data Centers

Data Search, Access & OrderData Search, Access & Order
Multiple data search types:– By discipline view(e.g. Land) (New)– By physical parameter (e.g. Albedo)– By instrument or platform(e.g. MODIS, TERRA)– By spatial and/or temporal coverage– By data granule identifier and other product
specific attributes– By specialized instrument browse
