Both the tree-ring and instrumental data were prewhitened using autoregressive modeling, with instrumental persistence added back in to the reconstruction. Series significantly correlated (> 0.05 level) with the instrumental record were used to reconstruct Niño-3 SSTs. A nested procedure (in which the number of chronologies declines back in time) was used to develop the longest possible reconstruction, with iterative nests beginning in 1408, 1507, 1608 and 1709. The final reconstruction was developed by averaging early and late calibration reconstructions within each nest, and splicing these series together after their variance and mean had been adjusted to that of the 1709-1978 nest. All chronologies were compiled from indices of tree growth (primarily ring width) detrended to remove biological trends (Cook 1985). ABSTRACT SUPPLIED BY ORIGINATOR: The instrumental record is too brief for evaluation of the El Niño-Southern Oscillation (ENSO) system and its long-term response to climate forcing. To supplement these data, we use a new reconstruction of December-February Niño-3 sea surface temperatures based on subtropical North American tree-ring records to investigate aspects of ENSO variability over the past six centuries (AD 1408-1978). Spectral analyses reveal that the reconstruction best resolves variability within the "classical" ENSO band of 2-8 years. A low amplitude ENSO epoch in the 17th to 18th centuries broadly coincides with "Little Ice Age" conditions over much of the globe. The detailed behavior shows good agreement with shorter tree-ring reconstructions of ENSO over the past few centuries, but differs at times from other longer coral ENSO records and recent model simulations of past ENSO behavior. We discuss possible reasons for these discrepancies.
