The Antarctic_Ice Sheet_cci project aims to produce long term and reliable climate satellite data records required by the scientific user community. These datasets will improve understanding of present day change on the Antarctic Ice Sheet and provide data for models at a higher spatial and temporal resolution than is currently available, thereby improving estimates of future change.

In 2014 a community wide user survey was conducted to determine which Antarctic geophysical datasets are most useful for the user community, what the spatial and temporal resolution of the satellite Earth observation datasets should be, and where the priority regions of the Antarctic Ice Sheet are. The survey was very successful with over 113 responses, of which 55% had over 10 years of experience in their field of interest.
The respondents primarily had an Earth Observation background, however 6 responses were also received from ‘decision makers with interest in Cryosphere and its changes,’ indicating that Antarctic Ice Sheet products are required to help make informed policy decisions.
Mass balance, ice velocity, surface elevation change and grounding lines were determined to be the most important data products (see figure). Consequently these products will be produced by the CCI Antarctic Ice Sheet project over the next three years. Read more »
The ESA CCI (Climate Change Initiative) Antarctic Ice Sheet project has released Gravimetric Mass Balance products.
The Antarctic_Ice_Sheet_cci project (AIS_cci) is well represented at Living Planet.
The Yearly Review Meeting will take place April 13th and 14th at Estec.
This will be a combined Antarctica_Ice_Sheet_cci and Greenland_Ice_Sheet_cci meeting with the CRG team present.
For AIS_cci this will be the first official opportunity for assessment of the fresh release of Data Products.
The Progress Meeting no 3 was held in Oslo February 2 and 3, hosted by S[&]T AS.
The first set of Data Products for the parameters SEC, IV, GLL and GMB was selected during the meeting - for release in April 2016.
The AIS_cci project is on schedule. The coming release of Data Products is a major milestone for the project.
The release of the Data Products will be accompanied with a fresh Newsletter and proper announcements.
A new study released by NASA scientist Jay Zwally and colleagues in the Journal of Glaciology, receiving wide coverage in the media last month, reports an 82 Gigatons per year increase of land ice in Antarctica during the period 2003-2008. The study received much skepticism from other leading scientists in the field, as there are many indications that point at the contrary: ice loss, possibly irreversible. How does this new study fit in that picture, what are the consequences for expected sea level rise and are these numbers correct? Glaciologist and polar scientist Jan Wuite, working at Enveo in Innsbruck and involved in various international studies related to Antarctica explains. Read more »
The Antarctic_Ice_Sheet_cci (AIS_cci) project has passed milestone one. The documents from task one are approved and we are preparing for Progress Meeting two in Copenhagen. The meeting will take place together with the Greenland_Ice_Sheet_cci meeting. Read more »
The Antarctic_Ice_Sheet_cci project performs an open round robin experiment to compare and evaluate algorithms for the generation of Gravimetric Mass Balance (GMB) products. Since the experiment is carried out in close collaboration with the Greenland_Ice_Sheet_cci project it deals with both the Antarctic Ice Sheet and the Greenland Ice Sheet. Beside GRACE data synthetic datasets of global mass changes form the basis for the algorithm evaluation.
The Antarctic_Ice_Sheet_cci team is looking forward to receive your contribution by September 30th 2015 (extended deadline). All contributions will be analysed anonymously.
The Antarctic_Ice_Sheet_cci project has released Newsletter Issue 2 per April 2016 - timed for Living Planet and the 1st release of data products.
Antarctic_Ice_Sheet_cci has released Newsletter Issue 1 and ESA has edited and launched a Special Issue for the COP-21. There are only minor editorial differences between the two. Read more »
