The National Space Science Data Center (NSSDC) drafted a document, NSSDC Earth Science Data Transition Plan, in June 1992 to identify what data sets held at NSSDC need to be migrated to which Distributed Active Archive Center (DAAC). The appendices in that document, which list all the relevant digital Earth science data at NSSDC, were revised in June 1994.
Based on NSSDC's input, a modified list was prepared in January 1995 and recommended by Dr. Stephen Wharton, the Earth Observing System Data and Information System (EOSDIS) Project Scientist, to NASA Headquarter's Earth Science Data and Information System (ESDIS) for implementaion. All category 1 data, namely those identified as desirable by a DAAC, were given priorities for immediate transition from NSSDC to that DAAC.
In June 1995, at the request of two DAACs, ESDIS funded NSSDC to convert some existing media to the DAAC-desired media and to restore selected data that were older than 10 years. An overview of data transfer activities between NSSDC and each of the DAACs is provided below. To search for specific data sets, please see the Earth Science Data Already Transferred Out of NSSDC.
In July 1997, NSSDC signed a Memorandum of Understanding (MOU) with Mr. Greg Hunolt of ESDIS to transfer the ownership and responsibilities of all remaining Earth science data (both digital and analog) held by NSSDC. Storage arrangements will remain in effect until such time that ESDIS is ready to take physical possession of these data.
Data transfers between NSSDC and the various DAACs are as follows:
