After the successful launch of CryoSat-2 in April 2010,
the first direct validation campaign of the satellite is
planned for spring 2011. DTU Space has been involved
in ESA’s CryoSat Validation Experiment (CryoVEx) with
airborne activities since 2003. To validate the prelaunch
performance of the CryoSat radar altimeter (SIRAL), an
airborne version of the SIRAL altimeter (ASIRAS) has
been flown together with a laser scanner in 2006 and
2008. Of particular interest is to study the penetration
depth of the radar altimeter over both land- and sea ice.
This can be done by comparing the radar and laser measurements
with in situ observations.
Here, an overview of the prelaunch airborne campaigns is
given, together with results of the ASIRAS performance
over land- and sea ice. The observations, used in this
study, are obtained from the Greenland ice sheet and from
both multiyear and first year sea ice.
