ensembleGenerator: ClimateNA Ensemble Generator

In Silva21-irss/silvR21: Processing Tools for the Silva21 Project

ClimateNA Ensemble Generator

Description

This function uses the desired SSPs and variables to generate averaged ensembles. Its outputs will consist of a series of ensemble CSV files, each consisting of the average value for each variable under every SSP scenario and time frames. This function is only used with monthly data outputs.

Usage

ensembleGenerator(
  files,
  tFrame = c("M", "S", "Y"),
  var = c("Tmax", "Tmin", "PPT", "DD5", "NFFD", "PAS", "CMI"),
  ssp = c("S1", "S2", "S3"),
  years = c("Y2", "Y3", "Y4", "Y5"),
  concatenate = TRUE
)

Arguments

files	The list of files provided by the projClimateNA20Y output, after using the AnnualSeasonalMeans function to process annual and seasonal averages/sums.
tFrame	The variable time frames included in the climate data. If the AnnualSeasonalMeans tool has been used, then the default value is desired. Otherwise, 'M' represents monthly, 'S' represents seasonal, and 'Y' represents annual time frames.
var	The desired variables to produce averages of. Variables include : 'Tmax','Tmin','Tavg','PPT','Rad','DD_0','DD5','DD18','DD_18','NFFD','CMI','PAS','Eref','CMD','RH'. Default value includes 'Tmin','Tmax','PPT','DD5_','NFFD','CMI','PAS'.
ssp	The SSP scenarios. 'S1' = 'ssp126' ; 'S2' = 'ssp245' ; 'S3' = 'ssp370' ; 'S5' = 'ssp585'. Default value is c('S1','S2','S3').
years	The 20-years time frames selection. Options include : 'Y1' (2001-2020); 'Y2' (2021-2040); 'Y3' (2041-2060); 'Y4' (2061-2080); 'Y5' (2081-2100).
concatenate	logical. If TRUE, all of the GCM ensemble data is concatenated into one mega file and producing a second file containing the GCM emsemble area's mean for each variable.

Value

Directory with ensemble files as CSVs

#files <- list.files(pattern='*.csv$') # Access all CSV files
#ensembleGenerator(files) # Generate ensemble using the default parameters
