simple.precipitation.intensity.index: Simple Precipitation Intensity Index

In ECA-D/climind: ECAD Implementation of Climdex Routines

Simple Precipitation Intensity Index

Description

This function implements the ETCCDI Simple Precipitation Intensity Index.

Usage

simple.precipitation.intensity.index(daily.prec, date.factor)

Arguments

daily.prec	Data to compute index on.
date.factor	Date factor to split by.

Details

The simple precipitation intensity index is computed by taking the sum of precipitation in wet days (days with >1mm of precipitation), and dividing that by the number of wet days in the period. This gives the mean precipitation in wet days.

Value

The mean precipitation in wet days for each period (as defined by date.factor).

Examples

prec.dat <- c(0.1, 3.0, 4.3, 0.9, 1.3, 6.0, 0, 0, 4.0, 1)
phony.date.factor <- factor(rep(1:2, each=5))
sdii <- simple.precipitation.intensity.index(prec.dat, phony.date.factor)
