Parameter generators for mass accumulation rates

pb210_mass_accumulation_constant(value = 0.15)

pb210_mass_accumulation_rlnorm(mean = 0.15, sd = 1)

Arguments

value, mean

An accumulation rate, in kg / m2 / year.
sd

For random (log)normal accumulation rates, the log standard deviation. The default is 1, which results in highly variable sedimentation rates. This is useful for testing pb210_crs().

Value

A function of a single parameter, age, which is a (decreasing) vector of ages.

Examples

age_compare <- tibble::tibble(
  ages = 150:0,
  constant = pb210_mass_accumulation_constant()(ages),
  rlnorm = pb210_mass_accumulation_rlnorm()(ages)
)
