SIRAL Acquisition Mode Monitoring

Source: L2 GDR-A (all acquisition modes) · Variable: flag_instr_mode_op_20_ku

Instrument measurement mode of each 20 Hz measurement, derived from the configuration bits in the L0 data: Low Resolution Mode (LRM), Synthetic Aperture Radar mode (SAR) and SAR Interferometric mode (SARin). The mode is selected on board from the CryoSat-2 geographical mode mask.
