  1. Polar Space Task GroupStatus Report EC-PORS-5 - 21 February 2014 Wellington, New Zealand

  2. Latest Results (other than Inf.11) • New Developments • Evolution in Satellite based Services • New and Forthcoming Sat. Missions • PSTG Requirement initiatives • Key Meetings in 2014 EC-PORS-5 25-28 Feb. 2014

  3. CryoSat: Sea Ice Thickness vs. Model PIOMAS Model CryoSat 2011 2012 2013

  4. Sea Ice Thickness vs. Model

  5. CryoSat sea ice thickness Data from CryoSatshow interannualvariability in Arctic sea ice volume, with autumn 2013 value 50% higher than in 2012 (though still amongst lowest in last 30 years. In October 2013, CryoSat measured approximately 9,000 cubic kilometers of sea ice compared to 6,000 cubic kilometers in October 2012. About 90% of increase in volume due to the retention of thick, multiyear ice around Northern Greenland and the Canadian Archipelago Sea ice dynamics monitoring fundamentalto mass balance understanding EC-PORS-5 25-28 Feb. 2014

  6. New: EUMETSAT Operational Antarctic Sea Ice Drift Products See: http://saf.met.no/p/ice/lr_ice_drift.html EC-PORS-5 25-28 Feb. 2014

  7. Satellite derived Ice Shelf Calving fluxes/basal melt rates Calving Flux – Green; Basal Mass loss - Orange • 0 = (Basal Mass Loss + Surf Mass Balance + Grounding Line Flux) - Calving Flux • Depoorter (2013) results using Satellite radar/laser altimetry + InSAR ice velocity map (for mass flux across grounding line) • Total Calving flux 1,321 +/-144 GT/yr • Basal mass loss -1,454 +/-174 GT/yr consistent with ocean model estimates • Half of ice shelf mass lost by basal melting before the ice reaches the calving front • Smaller calving fluxes than previously thought • Data Needs: Long term altimetry + ice sheet wide InSARmonitoring (for velocity) Depoorter et al (2013): Nature doi:10.1038/nature12567 (m yr–1) EC-PORS-5 25-28 Feb. 2014

  8. ESA-NASA Ice Sheet Mass Balance Intercomparison Exercise (IMBIE) • IMBIE combined satellite altimetry, interferometry, and gravimetry data from the same regions, time spans, and models to examine ice sheet balance. • Estimated mass change rates for four ice sheet regions (Greenland, East Antarctica, West Antarctica, and the Antarctic Peninsula) between 1992 and 2012. Image from Shepherd et al. 2012. • Interannual variability driven by Surface Mass Balance and ice stream velocity • Greenland is most dominant contributor to sea level EC-PORS-5 25-28 Feb. 2014

  9. NOAA NRT Sea Level Record http://ibis.grdl.noaa.gov/SAT/SeaLevelRise/LSA_SLR_maps.php http://ibis.grdl.noaa.gov/SAT/SeaLevelRise/LSA_SLR_timeseries.php • Global mean and regional rate of change in sea level monitored • Consequences of glacier/ice sheet mass input (eustatic) and steric effects monitored by altimeters EC-PORS-5 25-28 Feb. 2014

  25. Summary and Considerations for EC-PORS • EC-PORS requested to reflect on PSTG progress • Space Agencies can be tasked effectively as illustrated by ice sheet example of response to a consolidated set of user requirements • Similar sets of consolidated requirements are a prerequisite to effective planning and coordination of PSTG Agency commitments • EC-PORS Task Teams to reflect on how best to harmonise PSTG strategic priorities with GCW and GIPPS foci and activities • PSTG rep. simply cannot attend all GCW, WWRP meetings • For EC-PORS to consider how best to capture consolidated space observation needs of observing system initiatives such as SAON, SOOS, etc. • EC-PORS to consider providing any critical needs or strategic priority inputs to forthcoming PSTG4 meeting in Sept/Oct 2014
