#' Example monthly precipitation isoscape data
#'
#' Three months (July, August, September) of a d2H precipitation isoscape,
#' provided to demonstrate \code{\link{makeMultiMonthIsoscape}}.
#'
#' @format A data.frame with 43200 rows and 5 columns: \code{x} and \code{y}
#'   coordinates plus three monthly d2H layers \code{d2h_07}, \code{d2h_08},
#'   and \code{d2h_09}. Convert to a multi-layer SpatRaster with
#'   \code{rast(iso_monthly, type = "xyz")}.

#' Example monthly precipitation isoscape standard-error data
#'
#' Standard-error surfaces matching \code{\link{iso_monthly}}: three months
