International Journal of Climatology 28: 1-20 NOTES: This is a re-analysis of the Konini Forks collection, originally archived as ITRDB newz008. Several cores have been deleted from the original collection (KON561, KON562, KON563) and pre-1770 AD data have been deleted from other cores, due to poor correlations.
