The NSIDC DAAC’s Role in Sustaining the IPY Data Legacy
Ronald L. S. Weaver, Marilyn Kaminski
NSIDC - CIRES
NASA’s Snow and Ice Distributed Active Archive Center at the National Snow and Ice Data Center (NSIDC DAAC) has been awarded a follow-on contract for the coming five years. The scope of this work is specific to NASA’s Earth Observing Priorities but meshes well with International Polar Year needs. We will discuss the intended tasks for the NSIDC DAAC in relation to the needs for IPY data management, pointing out challenges to either the DAAC specifically or to the IPY community generally.
The challenges to the NSIDC DAAC include better integration of our legacy data with our Earth Observing System (EOS) satellite mission data, and integration of our data and systems with the greater data management community and programs such as the IPY. We must continually improve the ways we describe and deliver our data to users, enhancing their ability to use it in innovative ways. Our approaches to meeting these objectives include:
Adapting our data systems to the ever-changing user needs and technology landscape. Major thrusts include deriving gains in programmer and software engineer efficiency through greater standardization of software development processes; increasing use of subsetting to deliver larger quantities of data with available network bandwidth; standardizing metadata within the NSIDC DAAC and between our data center collaborators; harmonizing formats and spatial/temporal coverages for data and data types to enable more powerful visualization, online analysis and data integration.
Implementing existing and new geophysical algorithms for cryospheric and polar processes including sea ice concentration and types, ice surface temperature, sea ice motion, ice sheet topography and ice volume change, surface albedo, snow extent, and snow water equivalent.
Acquiring new data streams and developing new data products (including new data types and improved formats) to meet NASA and EOS science objectives for the cryosphere and polar regions.
