HyetosRepScheme {HyetosMinute}R Documentation

Level 0, Level 1, Level2 and Level 3 repetitions

Description

The function HyetosRepScheme disaggregates daily rainfall into hourly or sub-hourly rainfall. It is the main subroutine of DisagSimul.test and DisagSimul functions.

Usage

HyetosRepScheme(L,l,f,k,a,v,mx,sxmx,WeiTF,iOTA,Zhist,
da,F,MinNumLevel1Rep,TotalNumRep,timescale)

Arguments

L

A positive integer that specifies the number of wet days followed by one or more dry days.

l

A positive number that specifies the rate of Poisson process. The time units are days (d).

f

Constant φ=γ/η.

k

Constant κ=β/η.

a

Shape parameter of gamma distribution

v

Scale parameter of gamma distribution

mx

A positive number that specifies the mean of cell intensities.

sxmx

A positive number that specifies the ratio of standard deviation to mean cell intensity.

WeiTF

Logical value that specifies if the intensities follow the Weibull distribution.

iOTA

Ratio ι=μ_x/η for the case of Bartlett-Lewis model with dependent intensity-duration, NA otherwise.

Zhist

Vector of the original daily depths of the wet days sequence.

da

A positive number that specifies the distance used to judge whether synthetic daily depths resemble the real ones. Default value is DistAllowed=0.1.

F

A positive number that specifies the factor for Level 1 repetitions allowed. Default value is FacLevel1Rep=20.

MinNumLevel1Rep

A positive integer that specifies the minimum number of Level 1 repetitions allowed. Default value is FacLevel1Rep=50.

TotalNumRep

A positive integer that specifies the total repetitions allowed. Default value is TotalRepAllowed=5000.

timescale

The time scale of disaggregated data (number) (e.g. 1/60 for 1 min, 1/30 for 2min, 1/12 for 5 min).

Value

u

Matrix of adjusted hourly rainfall depths of L wet days (proceded and followed by at least one dry day).
