#' Atmospheric radiocarbon for the period 1950-2010 reported by Hua et al. (2013) for 5 atmospheric zones.
#' @usage data(Hua2013)
#' @format
#'   A \link{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.
#'   \describe{
#'     \item{\code{Year.AD}}{Year AD}
#'     \item{\code{mean.Delta14C}}{mean value of atmospheric radiocarbon reported as Delta14C}
#'     \item{\code{sd.Delta14C}}{standard deviation of atmospheric radiocarbon reported as Delta14C}
#'     \item{\code{mean.F14C}}{mean value of atmospheric radiocarbon reported as fraction modern F14C}
#'     \item{\code{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.
