Antarctic Ice Sheet CCI

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. Consequently these products will be produced by the CCI Antarctic Ice Sheet project over the next three years.

Antarctica_Ice_Sheet CCI+ has been officially kicked off!

The Antarctica Ice Sheet Climate Change Initiative Extension (CCI+) has officially started. 

The kick off meeting took place on 23rd May 2019 at ESTEC, The Netherlands. 

The consortium is sill the same, except for two partners that have left it: BAS and TUM.

A new Digital Elevation Model (DEM) is available for Antarctica

"Around 250 million measurements taken by ESA’s CryoSat over the last six years have been used to create a unique 3D view of Antarctica, offering a snapshot of the undulating surface of this vast ice sheet.

CryoSat’s radar altimeter detects tiny variations in the height of the ice across the entire continent, including on the steeper continental margins where the vast majority of ice losses occur. Read more »
