X: Indicates principal contribution to the objectives. 
(X): Indicates limited applicability. 
(1): For large-scale circulation accurate orbit determination over short arcs is required. 
(2): For solar tides, measurements from other satellites in complementary orbits are 
required. 
(3): The altimeter and Active Microwave Instrumentation are mutually supportive in deriving 
the wind and wave fields.
