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?
