northwest North American training set (Barley 2006)
Variable name changed from age14C to age during update from DKs csv files.
This dataset is from version 2 of the Arctic Holocene Transitions Database, and has been expanded to include an ensemble of chronologies, which are included in this file. This is described in McKay et al., 2018: doi:10.1029/2018GL079773
