climatology_threshold_exceedence: Get climatological prediction for exceedence probabilities.

In SeaVal: Validation of Seasonal Weather Forecasts

Get climatological prediction for exceedence probabilities.

Description

The climatological prediction for exceedence probabilities is the fraction of observed years where the observation exceeded the threshold. It's calculated from leave-one-year-out climatology.

Usage

climatology_threshold_exceedence(
  obs_dt,
  o = "prec",
  by = setdiff(dimvars(obs_dt), "year"),
  thresholds = c(200, 300, 350, 400)
)

Arguments

obs_dt	Data table containing observations.
o	column name of the observation. Mostly observed precipitation in mm.
by	By which columns should be grouped?
thresholds	vector of thresholds for which the exceedence probabilities should be derived.

Value

Data table with the climatological probabilities of exceedence for the provided thresholds.

Examples

dt = climatology_threshold_exceedence(chirps_monthly)
