  1. Managing IceBridgeAirborne Mission Data at theNational Snow and Ice Data Center M. Kaminski, M. Brodzik, J. Deems, T. Scambos National Snow and Ice Data Center, University of Colorado Boulder, Colorado USA 80309 April 4, 2011 marilynk@nsidc.org

  2. NSIDC’s IceBridge Data Management Project goals: Ensure preservation of data Increase and broaden usage of data Project tasks: Provide access to related data that is safely archived elsewhere Data brokering Data archive - ongoing flight campaign data - pre-IceBridge data Also archive flight reports; Level 0 data; ancillary data; broad scope of pre-IceBridge data Portal with map-based access using geometry of flight lines; data readers, documentation, … Tools & services Value-added products Compiled data sets for streamlined analysis

  3. IceBridge Data Providers Global Hawk UAF ICECAP P-3 DC-8 POS/AV POS/AV HiCARS PARIS Acc Radar Snow Radar BGM-3 NSERC CAMBOT Ku-Band Radar Lidar Scanner WISE Air Grav LVIS platform DMS GEOMET ATM Lidar Profiler IST IST IST IST IST IST IST IST IST IST Sigma Space instrument MCoRDS POS/AV team

  4. NSIDC IceBridge Data Web Site nsidc.org/data/icebridge

  5. Data Availability No data restrictions or period of exclusivity New data announced through news page, RSS feed, user notices Currently data is downloadable from ftp site Organized by instrument and campaign; no spatial filter

  6. 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 email 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

  7. 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

  8. 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

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