L2 Surface Height Monitoring

IPF Baseline:

E D C B A

Phase:

Operational Commissioning

Cryosat L2 data provides the calculated Surface Height for each of its 3 retrackers (L2 field 37,38,39) w.r.t. the WGS84 ellipsoid for each 20Hz measurement record.

This tool provides:

• Mean L2 Surface Height for each retracker and Standard Deviation trends at specified global locations. Locations are chosen to characterise different surface types, environments and CryoSat modes. You can select the radius of the area sampled around each location.
• Global and polar plots of L2 Surface Height maps and histograms for each 30-day data take, SIRAL mode and retracker.

Local L2 Surface Height Trends

Mean L2 height and the standard deviation of height measurements from each retracker for each cycle are available for the following locations:

*note that the mode mask maps shown above are typical examples and not necessarily the latest version of the CryoSat mode mask. Locations have been chosen where the mode mask is currently stable.

Global and Polar Maps and Histograms of L2 Surface Height per 30-day Cycle

Global and Polar Maps and Histograms of the L2 Height variable for each retracker are available for each 30-day cycle. Height from individual SIRAL modes or all modes can be shown.
