Minimize Cycle 50-59


Ers2 Wind Scatterometer L2 - Cycles 50-59

The following table gives the number of orbits available per cycle and the number of explained and unexplained missing orbits. Explained missing orbits cannot be recovered because is effectively data lost due to platform/instrument anomalies, and acquisition errors. Unexplained missing orbits might be recovered during next reprocessing campaign and are mainly due to corruption occurred during the transcription processes of the raw telemetry data from tape units to hard disks.


  Unexplained Missing orbits
  Missing orbits(due to Instrument/Platform Unavailability,Ground Segment Station Unavailability, Orbit Control Manouvre, and Unplanned Orbits)
