IntCal radiocarbon carbon calibration curves
Impact of Research
The most recent IntCal calibration curves (IntCal20, SHCal20, Marine20) were published in August 2020 and have already been cited over 300 times. They have been used to enhance understanding of the timing of events in archaeology and earth sciences as well as providing a proxy record for solar production for climate models. The curves are used by all major commercial 14C laboratories which generate approx. £40M annual revenue.
