GLIMS Data Base at NSIDC: “GLIMS World Data Archive” Development Activities: host data base content advisory group develop functional requirements for data base (with GCC) design and implement data base (with GCC) design and implement web-based data submission and user query
GLIMS Data Base at NSIDC: “GLIMS World Data Archive” Operational Activities: archive glaciological data derived from the imagery by the regional centers provide web-based user services for GLIMS-derived data provide reports on data submission and user activity to GCC liaise with GCC re. image collection schedule report on scientific significance of data archive (with GCC, EDC and RCs)
GLIMS Data Base at NSIDC: “GLIMS World Data Archive” Assumptions: Terra ASTER operations successful ECS operations successful funding initiative successful
