Depletion maneuvers are inclination maneuvers (back and forth) and are placed over land as much as possible. Sea surface height measurements from telemetry during the maneuvers is expected to be degraded. In addition, products could be impacted 30 minutes before each maneuver and up to 2 hours following each maneuver. Wind and wave content in the products will not be impacted.
