ReadCMIP5Ensemble: Read the multimodel-ensemble of CMIP5 climate model data.

In EarthSystemDiagnostics/ecustools: A miscellaneous collection of R functions for working with time-series and paleo data.

Description

Reads the multimodel-ensemble of CMIP5 climate model data. It expects a filelist (txt file with two columns, first column model name e.g. CCSM4, second column number of ensemble members) and expects that the filenames are formatted in a simplified CMIP5 formatting except PREFIX_modelname_MIDDLE_ensmemberNumber_SUFFIX. The perl scripts for processing the CMIP5 simulations to this format are oder geonob1/ecus/pool/cmip5/scripts.

Usage

ReadCMIP5Ensemble(
  path = "",
  bFullEnsemble = TRUE,
  METAFILE = paste(path, "filelist.txt", sep = ""),
  DATADIR = path,
  PREFIX = "tas_Amon_",
  MIDDLE = "_historical_",
  SUFFIX = ".nc",
  varname = "tas"
)

Arguments

path	, [optional] path of the METAFILE named filelist.txt
bFullEnsemble	FALSE: read only first member; TRUE:Read all members
METAFILE	filename (and path) of the metafile (file list)
DATADIR	Path of the netcdf files (default = path)
PREFIX	prefix of the files e.g. "tas_Amon_"
MIDDLE	middle of the filename, e.g. "_historical_" or "_past1000_"
SUFFIX	"suffix"
varname	variable name to be read

Value

list(cdat, meta) cdat= List of pField objects meta: List of vectors: name = unique name, modelName = modelName... ensMember = Ensemble member, here 1..100
