The complex waveform datastream from CryoSat’s altimeter requires a sophisticated processing scheme, in particular for exploiting the synthetic aperture and interferometry techniques over ocean and ice surfaces.
The main data product is the 'Level-2' product, sometimes called the Geophysical Data Record. This contains the surface elevation along the ground track together with all auxiliary data needed to fully exploit these measurements.
Other data products are also available for specialised users (such as radar scientists) which contain the radar echoes at various levels of processing.
