New German global sea ice data set


The sea ice and snow pages at the Integrated Climate Data Centre (ICDC) at the University of Hamburg, Germany: These contain a number of unique data sets:

1) The Soil Moisture and Ocean Salinity (SMOS) sensor allows retrieval of the sea ice thickness as long as freezing conditions prevail. Data of the SMOS sea ice thickness are available for the daily Arctic at:

2) A variety of sea ice concentration algorithm data. The ARTIST sea ice concentration algorithm that is used to compute fine grid resolution daily ice concentrations at both hemispheres:

The near-real-time AMSR2 sea ice concentration that comes at a breath-taking grid resolution of 3.125 km, at

Because we are part of the ESA-CCI Sea Ice ECV project we host the first sub-set (more to come within the next month) of the sea ice prototype product under:

3) The fine spatial resolution AMSR-E data set of the Arctic lead area fraction:

4) SSM/I location of polynyas and thin ice areas for the winter Southern Ocean:

5) Finally, the melt pond cover fraction on Arctic sea ice for summers 2000-2011 derived from 8-day MODIS composites:

Please don’t hesitate to contact us in case you have difficulties to get, use, or interpret the data. We will be happy to assist you.

About Seelye Martin

Seelye Martin received his Ph.D. in engineering mechanics from Johns Hopkins University in 1967 then spent two years as a research associate in the Department of Meteorology at the Massachusetts Institute of Technology. In 1969 he took up a position in the School of Oceanography at the University of Washington where he is now an Emeritus Professor. Beginning in 1987, he taught courses on remote sensing of the oceans. Professor Martin has been involved with passive microwave, visible/infrared and radar ice research since 1979, and has served on a number of NASA and NOAA committees and panels involving remote sensing and high latitude processes. He has made many trips to the Arctic for research on sea ice properties and oceanography. From 2006-2008, he worked at NASA Headquarters as Program Manager for the Cryosphere, where he also served as program scientist for the ICESat-1 and ICESat-2 missions. After leaving Headquarters, from 2009 -2012, he worked in a variety of roles for the NASA high-latitude IceBridge remote sensing aircraft program. For this work, in 2012 he was awarded the NASA Exceptional Public Service Medal.
