Reference ellipsoid
|
T/P

|
Referencing time period
|
1993-1999 (7 years)
|
|
Domain
|
Global (80°S to 82°N)
– Oceanwide where altimetric data are available. EGM96 elsewhere and on
continents.
|
|
Spatial resolution
|
Regular grid with a 1/30° (2 minutes)
spacing (i.e. ~4 km)
|
|
Grid
|
10800 points in longitudes / 4861 points in latitude
|
|
MSS determination technique
|
Local least square
collocation method on a 6’ grid where altimetric data in a 200-km radius are
selected. Estimation on a 2’ grid based on SSH-EGM96 values (remove/restore
technique to recover the full signal). The inverse method uses local
isotropic covariance functions that witness the MSS wavelength content.
|
|
Estimation error level
|
YES (in m) – Negative
values are flagging coastal areas where the smoothed junction with the
continental EGM96 geoid is computed.
