Orbiting closer to the poles than any other satellite and carrying the first radar altimeter of its kind, CryoSat is providing scientists with the data they need to gain a deeper understanding of the relationship between ice and climate change. As with any Earth observation mission, it is important to validate the readings acquired from space. This involves comparing the satellite data with measurements taken in situ, usually on the ground and from the air.
For CryoSat, that means sending teams to one of the harshest environments on Earth. Scientists embarking on this campaign to the Arctic are not only facing the physical challenges of working in a bitterly cold and hostile environment, but also a huge logistical undertaking….
