  1. Sea ice science using Aqua AMSR‐E data: Retrieval of sea ice parameters and scientific accomplishments Thorsten Markus, Joey Comiso, Donald Cavalieri Cryospheric Sciences Branch NASA Goddard Space Flight Center Greenbelt, MD 20771

  2. AMSR-E Standard Sea Ice Products Except for the snow depth product, all products daily averages using (a) ascending orbits only, (b) descending orbits only, (c ) all orbits.

  3. Differences between NT2 and Bootstrap ice concentrations - Arctic Comiso and Parkinson, 2008

  4. Differences between NT2 and Bootstrap ice concentrations – Antarctic Parkinson and Comiso, 2008

  5. Comparison between AMSR-E and MODIS sea ice concentrations Cavalieri et al., 2010

  6. Comparison between AMSR-E and MODIS sea ice concentrations Cavalieri et al., 2010

  7. Comparison of thin ice areas in the Ross Sea Kwok et al, 2007

  8. Comparison of thin ice areas in the Ross Sea Kwok et al, 2007

  9. High resolution sea ice concentration product using 89 GHz Spreen et al., 2008

  10. For the small polynya, AMSR measures its variability even when its area is order of a single SSM/I pixel. This means that AMSR-E permits more accurate calculation of polynya heat losses, yielding the potential of improved estimates of Arctic polynyaproductivity. ScanSAR AMSR-E SSM/I Martin et al., 2004

  11. Retrieval of thin ice thickness in Sea of Okhotsk Nihashi et al, 2009

  12. Sea ice drift from AMSR-E data Meier and Dai, 2006; Kwok, 2008, Agnew et al., 2008 Agnew et al., 2008

  13. Merged MODIS/AMSR-Esea ice concentrations AMSR-E MODIS Merged MODIS Clouds SSM/I

  14. Determination of sea ice roughness using 6.9 GHz data Hong, 2009

  15. New mulityear ice mask for AMSR-E snow depth Snow depth product 10/2004 - 9/2005 Land Open ocean Multiyear ice Melt/freeze, Wx Summer melt

  16. AMSR-E snow depth forICESat ice thickness retrievals Zwally et al., 2008; Kurtz et al., 2009

  17. Summary • AMSR-E has proven to be a very stable instrument with excellent radiometric calibration and stability, and geolocation • The sea ice products are widely used • operational use of sea ice concentration products • development of new and improved sea ice concentrations (e.g higher resolution product) • use of sea ice concentrations and TBs for process studies (e.g. polynyas, heat fluxes, primary production) • merging AMSR-E with MODIS • and more • Hopefully AMSR-E will last until GCOM-W AMSR2 data will become available so that we can continue the time series of AMSR-E quality sea ice products.
