Data used to reconstruct carbon dynamics of Siikaneva, Kalevansuo and Lompolojänkkä.

<p>Peat core data from three Finnish peatlands used to reconstruct site-scale carbon exchange between the peatlands and the atmosphere. Basal peat radiocarbon ages; reconstructed peat area over time based on these basal ages; carbon accumulation data along multiple peat cores; additionally reconstructed peat type and methane emission rates.</p>
