Major Focus: Manifestations of Climate Change




     Collaboration on advancing unique GSFC capabilities
                      ICESat Mission Highlights
ICESat SIPS
   • Located at GSFC
   • One of the first EOS SIPS
   • Science processing under control of science
      investigators
   • Integrated into EOSDIS
   • Produces all Level 1 and 2 science products
   • Excellent history of adding value to data
      set – Release 31 accomplished
        Greenland Mass Balance Change
• Paper published in the Journal of Glaciology December 2010 is
  a culmination of years of work using repeat-track analysis from
  ICESat
                 ICESat Data Products
• Staff is implementing a large number of changes and additional
  parameters to the ICESat Data Products in anticipation of the
  final release processing.
• Staff is investigating remaining campaign level biases in the
  ICESat data – see next slide
ICESat Biases with respect to L3j campaign from
    Antarctic study region crossover analysis
ICESat 2 Mission Highlights

•   Staff is working with data from the Sigma Photon Counting Lidar
    data taken over 2 vegetation study areas and the Greenland Ice
    Sheet
•   Putting out datasets of “ATLAS-like” (ICESat-2’s instrument) for
    the Science Definition Team
•   Working on “Ground Finding” Algorithm which will automatically
    segregate ground signal from background counts. See plots on
    next page.
ICESat-2 Highlights
                       ICESat-2 SIPS
• Staff is developing the ICESat-2 Science Investigator-led
  Processing System
           – Consists of the ATLAS Science Algorithm Software
             (ATLAS) and the Scheduling and Data Management
             System (SDMS)

           – Software management plan and development
             schedule have been submitted to the project
• The ICESat-2 Ground Systems Engineer is a member of this
  task

             Systems Lead to put together all necessary plans,
             schedules, requirements and documentation.
MSL from MEASURES Reanalysis
           Estimated Stability of the 17-year Sea Surface Height Time Series




                                    MEASURES Data Set
Cycle-mean SSH differences between altimetric and tide-gauge sea levels evaluated at a 64-station
tide-gauge network, for TOPEX (cycles 1-364), Jason-1 (cycles 1-259), and OSTM/Jason-2 (cycles
1-44). Inter-mission bias adjustments derived from the Jason-1 and Jason-2 verification-phase
collinear SSH differences have been applied to form a “single mission” time series to estimate the
stability of the 17-year sea-surface height record. From Beckley et al, 2011, in draft. To be released
imminently on PODAAC.

Mass Flux Estimation: Temporal changes in gravity field are
determined in monthly (or shorter time) solutions which are
recovered w.r.t. a multi-year mean gravity field (e.g. GGM02C)
                   Δmass flux = Nmonth - N

        Fast Dynamic Response of The Greenland Ice Sheet to
         Climate Change From The Melt-acceleration Effect

 The observations have shown that
a seasonal variation in ice flow
                                        Elevation Change (dH/dt) (2003-2006)
velocity is strongly associated with
seasonal surface melt which causes      ICESat observation       Model result
increased basal sliding.                  (total change)         (dynamic change)

 A 3-dimensional time-dependent
ice flow model is developed and
applied to the Greenland ice sheet to
investigate the dynamic response to
climate change from the melt-
acceleration effect.

 The model incorporates a seasonal
basal sliding parameterization that
depends on estimates of the
meltwater penetration to the bed.

 The surface meltwater production
is estimated using satellite observed
surface temperatures during the time
period of 1982 -2006.                                        <

         Comments on Cost Performance
• Large influx of “Soft Money” and Tier One Project Funding
   – Efficient use of ICESat staff allowed both ICESat missions to
     be supported at significant cost savings (task 614-03,614-06,
     614-13)
   – DESDynI funds arrived with anticipated staffing increase.
     Obviously this will not happen. (task 698-06, 698-08, 698-09,
     698-14)
   These Tier One Tasks account for $868k of underrun

• Focus on meeting technical commitments and delivering
  maximum effort at least cost to Project Funding

•   We would significantly lower indirect costs
•   We would provide a single point-of-contact for NASA customers
•   We would integrate all subcontractor employees into a seamless team
•   We would provide comprehensive contract surveillance (and stand up robust surveillance
    system)
•   We would provide the Government with timely decision making, program autonomy to
    ensure a focus on GGSG performance, and rapidly address programmatic problems
•   We would infuse new personnel to meet conflicts for resources

    small businesses to GSFC
