Giant iceberg in the making

All eyes are on Antarctica's Larsen C ice shelf as a deep crack continues to cut across the ice, leaving a huge chunk clinging on. When it eventually gives way, one of the largest icebergs on record will be set adrift. Even before the inevitable happens, ESA's CryoSat mission can reveal some of the future berg's vital statistics.

Monitored by the Copernicus Sentinel-1 radar pair, the crack in the ice is now around 200 km long, leaving just 5 km between the end of the fissure and the ocean.

While we wait for Sentinel-1 to tell us when this 6600 sq km iceberg is spawned, CryoSat can reveal what the berg's measurements will be.

New CryoSat CUT ROEF file available

CryoSat CUT scientific users are informed that a new version of the CUT ROEF file is available for download.

From the CUT application, under the menu bar, users may select "Help > Check for ROEF updates" and then follow the instructions. Expert users are also informed that the new ground tracks have been uploaded to the Cal-Val FTP server.

CryoSat Antarctica DEM 1.2 now available online

The CryoSat Antarctica DEM described in this recent publication is now freely available for download. The file also contains the Product User Guide.

The DEM was created by CPOM and it is composed of approximately 250 million measurements taken by CryoSat between 2010 and 2016. It is now the most comprehensive picture of Antarctic ice elevation currently available and offers a wide range of applications - showing the surface of Antarctica in such detail means that it can be used for anything from planning fieldwork to modelling the ice sheet.

It also allows scientists to distinguish between changes in topography and ice motion when working with other satellite measurements, such as those used to calculate the balance between how much the ice sheet is gaining by accumulating snow and how much it is losing through melting and creating icebergs.

Users may freely use the DEM provided they give acknowledgement.

CryoSat SIRAL resumes routine operations

We are glad to inform all CryoSat users that the SIRAL anomaly announced on 02 June 2017 was successfully resolved.

The routine instrument planning resumed on 03 June 2017 at around 09:30 UTC with the first LRM segment. Analyses confirm that the instrument is performing nominally.

CryoSat SIRAL anomaly on 02 June 2017

CryoSat scientific users are informed that the SIRAL instrument is in stand-by mode from 03:54 UTC this morning due to an anomaly which is currently under investigation.

New CryoSat dataset with corrected mispointing angle for aberration of light available to users

A new dataset is now available to CryoSat users which contains Star Tracker mispointing angles corrected for the aberration of light. This dataset is particularly important for those users who are processing the data in Swath Mode. It essentially has no major impact on other applications.

It is noted that corrected values of the mispointing angles corrected for the aberration of light will be incorporated in the next release of the ice products called Baseline D, planned to be released next year.

Users can download the Technical Note, which describes this dataset. The yearly datasets can be downloaded from the these links: 2011, 2012, and 2013. Each dataset is approximately 500MB.

The missing years will be added to the current datasets once they have been processed and shall become available on the datasets page.

CryoSat reveals Antarctica in 3D

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.

Importantly, the satellite's orbit takes it to latitudes within 200 km of the north and south poles – closer than other Earth observation satellites.

To the Arctic for CryoSat and beyond

After the relative quiet of the long dark winter months, the Arctic will be a tad busier over the coming weeks as numerous researchers descend on this harsh, yet fragile environment. Their aim is not to disturb its beauty, but to join forces in an all-out effort to measure ice on land and sea.

Environmental changes in the Arctic are no longer only of interest to scientists.

The need to understand and respond to dwindling polar ice is being given increasing importance at global climate discussions and vital for adopting strategies to mitigate and to adapt to change.

CryoSat data access network maintenance on 08-09 March 2017

Cryosat-2 users are informed that a mandatory maintenance shall be performed on the network in Kiruna.

These works have been scheduled to take place between 08 March at 23:00 UTC and 09 March 06:00 UTC.

During that time users may prove difficulties in accessing Cryosat-2 data and NRT dissemination may suffer delays. We apologise for any inconvenience caused.

Browse, plot and download CryoSat products with VtCryoSat

VtCryoSat is a new ESA tool developed by VisioTerra (France) in order to easily browse and download CryoSat products through an interactive and graphical web interface. The tool is freely accessible and does not require any installation.

VtCryoSat uses a web browser to display profiles of CryoSat's geophysical parameters on a virtual globe, including numerous plot options, as well as the capabilities of exporting and downloading the corresponding products.

VtCryoSat requires few bandwidth and computational resources. It operates with all operating systems and mobile devices and works with the following browsers: Chrome, Firefox, Safari, Edge, Opera.

The VtCryoSat tool is available here.
