Atmospheric radiocarbon for the period 1950-2010 from Hua et al. (2013)

Description

Atmospheric radiocarbon for the period 1950-2010 reported by Hua et al. (2013) for 5 atmospheric zones.

Usage

data(Hua2013)

Format

A list containing 5 data frames, each representing an atmospheric zone. The zones are: NHZone1: northern hemisphere zone 1, NHZone2: northern hemisphere zone 2, NHZone3: northern hemisphere zone 3, SHZone12: southern hemisphere zones 1 and 2, SHZone3: southern hemisphere zone 3. Each data frame contains a variable number of observations on the following 5 variables.

Year.AD

Year AD

mean.Delta14C

mean value of atmospheric radiocarbon reported as Delta14C

sd.Delta14C

standard deviation of atmospheric radiocarbon reported as Delta14C

mean.F14C

mean value of atmospheric radiocarbon reported as fraction modern F14C

sd.F14

standard deviation of atmospheric radiocarbon reported as fraction modern F14C

Details

This dataset corresponds to Table S3 from Hua et al. (2013). For additional details see the original publication.
