acquisition strategies
Acquisition Strategies

OIB developed 3, basic acquisition strategies

February 2011

  • I. Establish once the bedrock topography grid and ice surface sampling epoch.
    • a) 5 km or less spaced flight lines parallel to elevation contours near coast and seaward of ice margin.
    • b) 10-20 km spaced flight lines parallel to elevation contours upstream.
    • c) Collect along center lines of most Greenland and Antarctic glaciers.
  • II. Extend coverage and repeat elevation measurements using high elevation lidar
    • a) Fill regions between low elevation flight lines
    • b) Repeat acquisitions in succeeding years for dh/dt
  • III. Use extended and base data to improve ICEsatslope errors, tie ICEsat and OIB to Cryosat, tie earlier data to ICEsat-2.

July 2012

  • Seasonal Strategy
  • 1) ICESat-2 continuity and a summer commissioning phase

January 2013

  • 1) OIB will fly a grid pattern the same glacier each season.
  • 2) OIB will fill coverage gaps so that regions are sampled at least once during OIB
  • 3) Remaining time devoted to acquisitions in support of ICESat and ICESat-2 science interpretation
  • 4) After 1-3 are complete, use remaining time to support other programs.

Re-evaluate the strategies as we approach ICESat-2

assessments
Assessments
  • Science team validated data quality through intercomparisons (e.g. cross-overs). Should there be a focus on experiments designed to refine error model predictions? http://bprc.osu.edu/rsl/IST/index_files/datacomparison.htm
  • Science team struggled with assessing impacts? How best to assess progress towards objectives and scientific contribution?
reporting
Reporting
  • Emphasize documenting impact of OIB on ICESat to ICESat-2 continuity. Will that reveal tweaks?
  • Should there be an annual OIB report on missions, progress towards objectives, and science accomplishments?
