Description Usage Arguments Details Value References See Also Examples

View source: R/climdex.r

Description

This function computes the climdex index R99pTOT.

Usage

1

Arguments

ci

Object of type climdexInput.

Details

This function takes a climdexInput object as input and computes the climdex index R99pTOT: the annual sum of precipitation in days where daily precipitation exceeds the 99th percentile of daily precipitation in the base period.

Value

A vector containing an annual timeseries of precipitation exceeding the threshold.

## 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",

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 R99pTOT index.
r99ptot <- climdex.r99ptot(ci)
