Corrected \({}^{14}C\) measurements from air samples collected at five Norwegian sites from 1962-1993.
Format
A data.frame
with 5 variables:
- site
Sampling station.
- start
Beginning date of the sampling period.
- end
Ending date of the sampling period.
- delta
Isotopic ratio \(\Delta^{14}C\) (per mil).
- sigma
Error on
delta
(per mil).
