In climdex.pcic: PCIC Implementation of Climdex Routines

Description

This function computes the climdex index PRCPTOT.

Usage

climdex.prcptot(ci)

Arguments

ci	Object of type climdexInput.

Details

This function takes a climdexInput object as input and computes the climdex index PRCPTOT: the annual sum of precipitation in wet days (days where precipitation is at least 1mm).

Value

A vector containing an annual timeseries of precipitation in wet days.

Examples

library(PCICt)

## Create a climdexInput object from some data already loaded in and
## ready to go.

## Parse the dates into PCICt.
tmax.dates <- as.PCICt(do.call(paste, ec.1018935.tmax[,c("year",
"jday")]), format="%Y %j", cal="gregorian")
tmin.dates <- as.PCICt(do.call(paste, ec.1018935.tmin[,c("year",
"jday")]), format="%Y %j", cal="gregorian")
prec.dates <- as.PCICt(do.call(paste, ec.1018935.prec[,c("year",
"jday")]), format="%Y %j", cal="gregorian")

## Load the data in.
ci <- climdexInput.raw(ec.1018935.tmax$MAX_TEMP,
ec.1018935.tmin$MIN_TEMP, ec.1018935.prec$ONE_DAY_PRECIPITATION,
tmax.dates, tmin.dates, prec.dates, base.range=c(1971, 2000))

## Create an annual timeseries of the sum of precipitation in wet days.
prcptot <- climdex.prcptot(ci)
