Figure 3

Spatiotemporal relation between annual, instrumental temperature and the PAGES Arctic 2k database. (a) Correlation coefficient between observed temperature at each grid cell and the revised Arctic 2k temperature reconstruction between AD 1880 and 2000. (b) Grid cells with significant (P<0.05; corrected for serial autocorrelation) correlations in (a) are shown in dark red. (c) Mean significant correlation coefficient at each grid cell for all records in the database AD 1880 and 2000. (d) Number of records with significant correlations (as in b) at each grid cell, this is equivalent to the number of records used at each grid cell to calculate the mean correlation coefficients in C. Location of records in database shown as light blue dots in C and D.
