CryoSat conquers ice on Arctic lakes

The rapidly changing climate in the Arctic is not only linked to melting glaciers and declining sea ice, but also to thinning ice on lakes. The presence of lake ice can be easily monitored by imaging sensors and standard satellite observations, but now adding to its list of achievements, CryoSat can be used to measure the thickness of lake ice – another indicator of climate change.

CryoSat, one of ESA's Earth Explorer satellites, carries the first radar altimeter of its kind. The instrument is traditionally used to determine the thickness of sea ice floating in oceans and to monitor changes in vast ice sheets on land, providing evidence of Earth's diminishing polar ice.
