Supplement to: Butzin, M et al. (2020): A short note on marine reservoir age simulations used in IntCal20. Radiocarbon, 1-7, https://doi.org/10.1017/RDC.2020.9

Beyond ~13.9 cal kBP, the IntCal19 radiocarbon calibration curve is based upon combining data across a range of different archives including corals and planktic foraminifera. In order to reliably incorporate such marine data into an atmospheric curve, we need to resolve these records into their constituent atmospheric signal and marine reservoir age. This dataset includes results of marine reservoir age simulations enabling this resolution, applying the LSG ocean general circulation model forced with various climatic background conditions and with atmospheric radiocarbon changes according to the Hulu Cave speleothem record. Simulation period is 54,000-10,700 cal BP, depth range is 0-50 m. Land values are flagged with -100. This dataset is an update of PANGAEA datasets doi:10.1594/PANGAEA.876733 and doi:10.1594/PANGAEA.775379.
