This is a new version of Image:Atmospheric radiocarbon 1954-1993.svg. I have changed the title because I'm using additional data sources now.

[edit] Description

The figure shows the relative ¹⁴C / ¹²C ratio in the atmospheric CO₂ as a function of time in the second half of the 20th century.

The plot was generated with gnuplot from data of atmospheric radiocarbon in Wellington, New Zealand 1954AD to 1993AD and in Vermunt, Austria 1959AD to 1983AD. The SVG file from gnuplot has been improved manually.
