create.ncdf.output.files: Creates output files for Climdex variables.

In ECA-D/ecad_indices_grid: Functions to compute CLIMIND indices over a NetCDF grid

Creates output files for Climdex variables.

Description

Creates output files for Climdex variables.

Usage

create.ncdf.output.files(
  cdx.dat,
  f,
  v.f.idx,
  variable.name.map,
  ts,
  time.origin,
  base.range,
  out.dir,
  author.data,
  metadata.config
)

Arguments

cdx.dat	The variable description data, as created by get.climdex.variable.metadata.
f	The file(s) being used as input.
v.f.idx	A mapping from variables to files, as created by get.var.file.idx.
variable.name.map	A mapping from standardized names (tmax, tmin, prec) to NetCDF variable names.
ts	The associated time data, as created by nc.get.time.series.
time.origin	The time origin, as specified in the source NetCDF file(s).
base.range	The base range; a vector of two numeric years.
out.dir	The output directory name.
author.data	A vector containing named elements describing the author; see create.indices.from.files.

Details

This function creates a set of output files for the set of variable parameters passed in cdx.dat, as created by get.climdex.variable.metadata. It copies metadata from input files as appropriate and adds new metadata as required.

Value

A list of objects of type ncdf4.

Examples

## Establish basic inputs.
author.data <- list(institution="Looney Bin", institution_id="LBC")
input.files <- c("pr_NAM44_CanRCM4_ERAINT_r1i1p1_1989-2009.nc")

## Prepare derived inputs.
f <- lapply(input.files, ncdf4::nc_open)
variable.name.map <- c(tmax="tasmax", tmin="tasmin", prec="pr")
f.meta <- create.file.metadata(f, variable.name.map)
climdex.var.list <- get.climdex.variable.list(names(f.meta$v.f.idx), "all", NULL)
cdx.meta <- get.climdex.variable.metadata(climdex.var.list, input.files[1])

## Create output files
cdx.ncfile <- create.ncdf.output.files(cdx.meta, f, f.meta$v.f.idx, variable.name.map,
                                       f.meta$ts, get.time.origin(f, f.meta$dim.axes),
                                       c(1981,1990), "/foo", author.data)
