Data Processing
The data used consisted of all ARGO profiles from the region 30S - 30N and 30E - 120E. The data was processed on a 10 days basis and the distribution of ARGO profiles were embedded on the contours to show the data sampling. The data sets obtained are passed through Real Time Quality control and the data are flagged accordingly as shown below.
0 No RTQC performed.
-
1 Good Data Set.
-
2 Probably Good Data Set.
-
3 Potentially Correctable Bad Data Set.
-
4 Bad Data Set.
The data sets flagged 1 and 2 are taken for griding and the rest are left out. The data griding was carried out as in:
"Kessler and McCreary, 1993: The Annual Wind-driven Rossby Wave in the Subthermocline Equatorial Pacific, Journal of Physical Oceanography 23, 1192 -1207"
Mixed Layer Depth: The MLD is defined as the depth at which the density is larger than the surface by 0.125 Kg m-3 [e.g., Levitus, 1982].
Heat Content: The Heat content calculation is based on:
HC = CpP | temp dz
Where
Cp = 4000.0 J/Kg .Deg is Specific Heat Capacity of water
P = 1024.5 Kg m-3
