L2 Freeboard Monitoring

IPF Baseline:

E D C B A

Phase:

Operational Commissioning

Cryosat L2 data includes a SAR mode computed Sea Ice Freeboard calculation for each 20Hz record.

This tool provides polar plots of sea ice freeboard (orbit view, gridded mean, median and maximum values, histograms) for each 30-day data take.

Notes:

• Freeboard is only available from Baseline-C onwards.
• Freeboard can be a small negative value where there is sufficient snow loading on thin ice.
• Freeboard is used in the calculation of sea ice thickness and volume. Near real time and seasonal thickness and volume data is now available from the CryoSat Operational Sea Ice Monitoring website courtesy of UCL/ESA and partner data providers.
• Plots on this page show freeboard parameter values where the freeboard_error flag is not set
