ERI: Calculates Components Of the ERI Index

In alasdairhunter/MagicWP7: Package for computing climate extremes from the CMIP data.

Description

Returns the temperature, precipitation and wind indexes required for the European Risk Index

Usage

ERI(proj, ref, index = "temp", period = 1, quantile = 0.9, threshold_upper = NULL, threshold_lower = 1, season_length = 365)

Arguments

proj	Vector of projected or forecasted temperatures
ref	Vector of temperatures from the references period
period	The width of the moving window for calculating the mean (heat index) or sum (flood index).
threshold_upper	The exceedance threshold above which values will be recorded.
threshold_lower	The exceedance threshold below which values will be recorded.
quantile	The quantile used to define the threshold from the reference data.

\tem

season_length The number of days in a year.

Value

$reference.index: the time series of the standardized reference index
$projection.index: the time series of the standardized projection index
$ref.index.sd: the sd of the non-standardized reference index
