The overall purpose of ESA’s CryoSat Validation Experiment (CryoVEx) 2011 was, for the first time, to directly validate the measurements from CryoSat‐2, through a coordinated major effort involving a large group of European, Canadian and US scientist.

One primary aim of the CryoVEx 2011 campaign was to provide data which could allow the optimal recommendation from the CVRT (CryoSat Validation and Retrieval Team), as to the optimal Level 1b and Level 2 retrieval algorithms, with which to reprocess the CryoSat‐2 data.


What was the outcome of CryoVEx 2011?

The CryoVEx 2011 campaign was a success. A total of about 100 flight hours, covering about 23,500 km, was flown with ASIRAS and ALS using DTU Space charted Twin-Otter.

The experiment demonstrated great collaboration and timing between a large group of European, Canadian and US scientists. The effort involved airborne activities coordinated with AWI Polar‐5 carrying an EM inducting sounder and ground teams on five different validation sites. A broad suite of data of the sea ice, Greenland ice sheet and the local ice caps Devon and Astfonna was collected giving a unique data set to optimise CryoSat‐2 Level 1b and Level 2 retrieval algorithms.
