Agricultural and Forest Meteorology, Vol. 288-289, 108014. DOI: 10.1016/j.agrformet.2020.108014 Maxwell, R.S., Belmecheri, S., Taylor, A.H., Davis, K.J., Guerrieri, R., Moore, D.J., Rayback, S.A.. 2021 in press. Global Change Biology, in press. Notes: New England Hemlock Transect, 10 sites along a 500+ km transect stretching from CT to ME. Data collected for Project "Estimating Forest Productivity Over Regional and Multi-Decadal Time Scales Using Carbon Isotopes in Tree Rings." While the larger project focused on carbon isotopes, here we present tree-ring width data associated with the project.
