Level-1A ECHO_SAR_Ku Product: Instrument Status

Level-1A ECHO_SAR_Ku Product: Instrument Status
PARAMETER SAR mode identifier
NETCDF NAME SAR_mode_l1a_echo_sar_ku
DESCRIPTION The SAR mode identifier is a flag that indicates the tracking mode of the SRAL instrument:
  1. Closed-loop mode: autonomous position of the range window using the median algorithms
  2. Open-loop mode: range window position based on a-priori knowledge of terrain altitude derived from a Digital Elevation Model (DEM)
UNITS (0b): Closed loop
(1b): Open loop
