NSIDC is in a unique position to partner with the NOAA/NESDIS
National Geophysical Data Center (NGDC) for an optimal
LTA solution for NSIDC’s ECS data holdings

Background• NSIDC was chartered by NOAA/NESDIS in 1982 to serve as
a national resource for cryospheric data and information.• NOAA/NGDC and NSIDC completed a NOAA-NASA LTA
pilot project in May 2001. Project demonstrated (among other things) bandwidth capacity between NGDC and NSIDC, and ability to ingest MODIS data into NGDC archive and access system.
• The “NOAA at NSIDC” project (http://nsidc.org/noaa/) maintains an on-line database while archiving data at NGDC, which is also in Boulder. “NOAA at NSIDC” data are accessible through NOAA & NSIDC catalogues and portals, and are documented and archived to federal standards.

Proposal
“Archive at NSIDC, with off site backup at NGDC”
![Page 5: Long Term Archival of ECS Data Held at the National Snow and Ice Data Center](https://reader036.vdocuments.site/reader036/viewer/2022062311/5a4d1b4d7f8b9ab0599a637f/html5/thumbnails/5.jpg)
NSIDC-NGDC Services Relevant to Archive and Science Operations
• Ingest (with processing/reprocessing)• Product generation• Archive (off-site, including archive of FGDC-compliant
DIF metadata)• Access (discovery via NASA and NOAA portals,
visualization and delivery)• User support (User Services office)• Science (research community contributions, on-site
scientists)

NSIDC’s Unique Qualifications
• Discipline expertise• Established archival relationship with
NOAA• Both a NOAA affiliated data center as well
as a NASA-funded DAAC - we meet both NOAA and NASA requirements
• Well established user base

User Demand for LTA at NSIDC
• The GLAS science team has requested NSIDC to be the LTA for GLAS data
• NSIDC’s science advisory group (PODAG) has endorsed NSIDC to archive its DAAC data holdings for the long term
• The NRC Committee chaired by John Walsh in their report “Enhancing NASA's Contribution to Polar Science” states that NSIDC (and ASF) are "natural vehicles for long-term archival” and recommends that “long term archival be a DAAC function”.

“Many of the pieces are already in place for successful LTA of ICESat and other NSIDC DAAC products at
NSIDC/NGDC”
