L2 Surface Type Flag Monitoring

IPF Baseline:

Cryosat L2 data includes a surface type flag flag_prod_status_20_ku for each 20Hz measurement record. The bit values of this flag provides a classification of the surface type (Ocean, Land, Continental Ice, Enclosed Sea) at nadir for the corresponding measurement location. The classification originates from a model provided by the ESA Geophysical CFI library.

This page provides global and polar plots of the L2 surface type flag for each 30-day data take.
