Cameron Lee,


This data set contains: 1) Tree-ring data (TRWdata_NHonly), 2) Fully-trained ensembles of artifical neural network models (ANNmodelsV07_TP-PCA-NHonly) based upon air masses (ANNmdlAM) and temperature and precipitation data (ANNmdlWX), 3) GWTC-2 air mass data (AMdata_NHonly), and 4) Monthly mean temperature (column 1), dewpoint (column 2 - un-used), and precipitation (column 3) data from TerraClimate (WXdata-NHonly) All of the above are saved in MatLab file format (.mat), and were used in the following research: Frequencies of multivariate air masses drive tree growth Cameron C.
