Multivariate Climate Field Reconstructions Using Tree Rings for the Northeastern United States. Journal of Geophysical Research: Atmospheres, Vol. 125, Issue 1, DOI: 10.1029/2019JD031619 NOTES: These data were collected as part of northeastern United States network of Atlantic white cedar. They were used to generate a gridded temperature reconstruction for the region. Two or three cores per tree were extracted from each tree and labelled as "A", "B" or "C".
