Indices (averages for different areas) of Sea Surface Temperature (SST) anomalies from the papers
These indices illustrate the Optimal Smoother (OS) analysis of MOHSST5 (version of GOSTA) dataset. The input data (the MOHSST5 version of the GOSTA dataset) from the U.K. Meteorological Office on which the analysis was based can be viewed e.g. here .
For each index we show three kinds of values: avGOSTA, straight average of the values available in the MOHSST5 dataset , avOS, the value corresponding to the OS analysis, and avOS_err, theoretical estimate for the rms error in the analyzed index.
Indices are defined as follows:
NAc North Atlantic (caption) NAc index [30N-50N, 60W-0W]. NAf North Atlantic (figure) NAf index [35N-70N, 75W-10W]. NAi North Atlantic (intended) NAi index [35N-60N, 60W-0W]. NP North Pacific NP index [30N-50N, 150E-120W]. NINO3 NINO3 index [5S-5N, 150W-90W]. NINO3.4 NINO3.4 index [5S-5N, 170W-120W]. WP Western Pacific (or Warm Pool) WP index [5S-5N, 120E-170E] EqNA Equatorial North Atlantic average EqNA [5N-20N,80W-15W]. GT Global equatorial mean [5S-5N]. GT30 Global tropical mean [30S-30N]. GL Global mean [30S-60N].
Names of the indices are consistent with those used in the papers, with the following exceptions:
ATTENTION: Up to January 18, 1997, NINO3.4 index mistakenly contained the values for NINO3. If you wanted to use specifically NINO3.4 prior to this date, you'd better redo you calculations (or re-download NINO3.4).
