• 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

data taken over 2 vegetation study areas and the Greenland Ice
Sheet
• Putting out datasets of “ATLAS-like” (ICESat-2’s instrument) for

segregate ground signal from background counts. See plots on
next page.
ICESat-2 Highlights

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.

Fast Dynamic Response of The Greenland Ice Sheet to
Climate Change From The Melt-acceleration Effect
Wei Li Wang, Jan. 2010
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
Small Business Participation
GSFC is getting small business credit for 87%
of the work being performed on GGSG.
People
SGT ICE (Integrity, Customers, Employees) has delivered
• High morale
• 100% employee retention
• Exceptional levels of Satisfaction
• A focus on our customers
• Badgeless Team
Safety
• Providing a safe working environment for its
employees has always been a priority for SGT.
• No reportable incidents this reporting period
• Program Manager is a permanent member of
SGT’s Corporate Safety Committee
• Deploying AED device for SGT HQ facility.
There are currently 4 GGSG employees trained
to use the AED in the HQ facility.
• Continuing our policy of requiring all new
employees to view the GSFC Occupation Safety
and Health video as part of their orientation.
• Sexual Harassment Prevention Training has
been provided to the SGT Team during 2010.
Management Summary
In our proposal to compete for the GGSG contract, we made the following
management promises:
• We would deliver a high level of technical participation at all staffing levels
• We would reward technical excellence through a robust bonus program
• 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
• We would operate as one company, not four by
– Flowing down all contract requirements to our teammates
– Use common policies and procedures
– Integrate teammates into GGSG program organization
• We would meet our Small Business subcontracting plan despite being a small
disadvantaged business ourselves, and provide an “Big Tent” to bring the talents of new,
small businesses to GSFC
