Time series corresponding to the 2nd mode from the singular value decomposition
(SVD) analysis of the cross-covariance between five-year running means of marine sea level
pressures (SLP) and sea surface temperatures (SST), which was
interpreted as the Pacific Decadal Oscillation (PDO)
mode of climate variability [Kaplan et al., 2000, Figure 12, 2nd panel], are accessible here through the
clone of the Ingrid Data Library (click on the pattern below, to get to the corresponding Data Library page, where the figure download and further visualization options are available):
SLP & SST-based PDO time series from the SVD analysis of the SLP & SST cross-covariance |
These PDO time series in the text format are here.
Three leading time series of the SVD analysis (1856-1990) are also
accessible through the clone of the Ingrid Data Library:
SLP
time series and
SST
time series.
For more details about this SVD analysis and other time series obtained from it, go to this page.
