From the ESA webpage:
The first map of sea-ice thickness from ESA’s CryoSat mission was revealed today at the Paris Air and Space Show. This new information is set to change our understanding of the complex relationship between ice and climate.
From an altitude of just over 700 km and reaching unprecedented latitudes of 88º, CryoSat has spent the last seven months delivering precise measurements to study changes in the thickness of Earth’s ice.
Check out their first map of sea ice thickness data (for Jan/Feb 2011) that they made to show what will eventually be the deal:
I want to get this out quickly, so I haven't checked yet to compare this image with the ice thickness models. But I will at some later point.
It's important to stress that however exciting all of this is, we're still some way off of 100% accurate data. Calibration will be an ongoing issue and as CryoSat-2 has now gone into its second year of data delivery and a substantial time series is being built up, its true value will start to emerge more and more.
I was really looking forward to watching the ESA webcast today, but unfortunately I slept through it because I had to work all night to make a deadline. The video of the presentation can be watched here. I highly recommend watching it. It has also been uploaded to Youtube:
