modSimulator

Description

Simulates using weather generator models specified using modelTag.

Usage

modSimulator(
  datStart = NULL,
  datFinish = NULL,
  modelTag = NULL,
  parS = NULL,
  seed = NULL,
  file = NULL,
  IOmode = "suppress"
)

Arguments

datStart	A date string in an accepted date format e.g. "01-10-1990".
datFinish	A date string in an accepted date format e.g. "01-10-1990". Must occur after datStart.
modelTag	A character vector of which stochastic models to use to create each climate variable. Supported tags are shown in details below.
parS	A list (names must match supplied modelTags) containing numeric vectors of model parameters.
seed	Numeric. Seed value supplied to weather generator.
file	Character. Specifies filename for simulation output.
IOmode	A string that specifies the input-output mode for the time series = "verbose", "dev" or "suppress".

Details

modelTag provides the main function with requested models. modelTag is vector of any of the following supported models:

• "P-ann-wgen" a four parameter annual rainfall model

• "P-seas-wgen" a 16 parameter seasonal rainfall model (phase angles must be specified via modelInfoMod=list("P-har12-wgen-FS"=fixedPars=c(x,x,x,x))

• "P-har-wgen" a harmonic rainfall model

• "Temp-har-wgen" a harmonic temperature model not conditional on rainfall

• "Temp-har-wgen-wd" a harmonic temperature model dependent on wet or dry day

• "Temp-har-wgen-wdsd" a harmonic temperature model where standard deviation parameters are dependent on wet or dry day

• "PET-har-wgen"a harmonic potential evapotranspiration model

• "PET-har-wgen-wd" a harmonic potential evapotranspiration model dependent on wet or dry day

• "Radn-har-wgen" a harmonic solar radiation model (MJ/m2)

pars=modCalibrator(obs=obs,modelTag=modelTag)   #Calibrate models
sim=modSimulator(datStart="1970-01-01",         #Simulate!
                 datFinish="1999-12-31",
                 modelTag=modelTag,
                 parS=pars,

                 file=paste0("tester.csv"),
                 IOmode="verbose")
plot(sim$P[1:365])                             #Plot first year of rainfall
