This example computes the cross-correlation at lags 0,1 and 2. If the cross-correlation at 0-lag only were desired, then it would be more efficient to use escorc. FYI: The linear correlation between the station based SOI (previous example) and the SOI derived from the 20th Century Reanalysis for the 1950-2010 period is 0.96. This example computes the cross-correlation at lags 0,1 and 2. If the cross-correlation at 0-lag only were desired, then it would be more efficient to use : Read gridded sea level pressure from the 20th Century Reanalysis, use proxy grid points near Tahiti and Darwin to construct an SOI time series spanning 1950-2010, perform lag-0 correlations between the SOI and SLP, SOI and temperature, and, SOI and preciptation. The later uses the GPCP data which spans 1979-2010. To more clearly delineate the main pattern structure correlations between, -0.1 and +0.1 were set to _FillValue. FYI: The linear correlation between the station based SOI (previous example) and the SOI derived from the 20th Century Reanalysis for the 1950-2010 period is 0.96. Source.
