Annual ring widths in the arctic-alpine dwarf-shrub species Betula Nana — Dataset from long-term alpine ecosystem research in Central Norway (LTAER-NO)

Abstract

Here we present a Data Paper with microscopically measured data on ring widths of the arctic-alpine dwarf shrub species Betula nana L. from Central Norway. We intend to continuously update the dataset in the future with further ring width measurements of this widespread shrub species.
