The ECCO global ocean state estimate over the 10-year period 1992 - 2001 |
9 |
is obtained by fitting WOCE data sets to a general circulation model. Data |
10 |
included are most of the in situ and satellite observations available during |
11 |
WOCE itself, and continuing. These data include satellite altimetry, scatterometry |
12 |
and SST fields, in situ hydrographic sections, XBT, P-ALACE, ARGO and TAO |
13 |
profiles, surface drifter velocities and Levitus climatological hydrography. |
14 |
As with all statistical estimation problems, one must provide a priori |
15 |
error covariances for all data sets, and the values and structures used in |
16 |
the estimation procedures are described here. |
