L2 Backscatter (Sigma0) Monitoring

IPF Baseline:

Phase:

Cryosat L2 data includes a radar backscatter (sigma0) value for each retracker (field 40,41,42) for each 20Hz measurement record.

This tool provides global and polar plots of L2 Backscatter maps and histograms for each 30-day data take, SIRAL mode and retracker.
