6European Geosciences Union, CR3.10 April 4, 2011 Tools and Services NSIDC provides a wide range of supporting services -Documentation -detailed user guide for each data set -User Services Office -personal service via or phone, with backup support from NSIDC programmers/scientists and instrument teams -Software for reading and interpreting data files -Data access portal (in work) -Web-accessible map-based interface to all available data -Planned comprehensive filtering by instrument/spatial/temporal parameters; easy access to data

7European Geosciences Union, CR3.10 April 4, 2011 IceBridge Data Access Portal First release June 2011 with access to flight lines and flight reports Frequent iterative releases for access to instrument data and value-added products Additional features will be user-driven

8European Geosciences Union, CR3.10 April 4, 2011 Value-Added Products: Goals -Process flight data to extract and calculate useful parameters for faster analysis -Update compiled gridded data sets (DEMs, bedrock elevation maps) rapidly -Facilitate the integration of new science algorithms into routine data distribution Two classes of Products: Along-Track Products – flightline tables of multiple sensor values and images, and multi-sensor derived values Gridded Products – post-campaign rapid updating of surface elevation DEMs, dH/dt grids, and bed elevation

9European Geosciences Union, CR3.10 April 4, 2011 Value-Added Products -Aligned (time and location) data sets, and pre-calculated parameters –All these data sets and derived parameters are co-located– Along-track product examples: Surface Properties Table Snow radar data image + Two layer picks (VAP) Snow thickness between layer picks (VAP) Subset of digital camera Subset of Laser altimeter Image histogram (VAP) Surface histogram (VAP)
