New paper on CryoSat performance over the ocean

10 February 2017

A significant reference for oceanographic applications of CryoSat has been published in the Remote Sensing of Environment journal.

The study was conducted by the UK's National Oceanography Centre Southampton (NOCS) within the framework of the ESA CryoSat Ocean Data Scientific Quality Control and Validation project.

This extensive evaluation of CryoSat ocean products includes noise and along-track spectral analysis as well as validation performed against the Jason-2 mission and several in-situ observations. The obtained results clearly confirm the excellent performance of CryoSat over the ocean.

But how do you know that measurements from successive satellites, even though identical in build, are like for like?
