Figure 5

Scatter plots (a–c), time series (d), histograms and boxplots (e–h) of September–November SSTs from various SST products compared with Enggano coral SSTs for the time period of 1958–2008 (a–c) and 1930–2008 (d–h). Note the extreme cooling during the pIOD events of 2006, 1997, 1994, 1967, 1963 and 1961, which is underrepresented in HadISST1 and ERSST5 (b–d) and the highly skewed distribution of the Enggano SSTs compared to the moderately skewed (SODA2, HadISST1) and symmetric (ERSST5) distribution of historical products (e–h). Boxplots show median, interquartile range and maxima/minima (whiskers) of the datasets. All time series have been centred to their mean.
