cellstatsNC: Summarise values of one or multiple NetCDF Files over time...

In RS-eco/processNC: R Package for processing large NetCDF files

Summarise values of one or multiple NetCDF Files over time and/or space

Description

Summarise spatial/spatio-temporal measurements of one or multiple NetCDF files to a raster stack or data.frame with desired spatial and temporal resolution

Usage

cellstatsNC(
  files,
  startdate = NA,
  enddate = NA,
  ext = "",
  cores = NA,
  filename = "",
  stat = "mean"
)

Arguments

files	character. A filepath or list of filepaths. Filepath should lead to a NetCDF file.
startdate	integer. Start year.
enddate	integer. End year.
ext	extent. If present the NetCDF file is subset by this extent.
cores	integer. Number of cores for parallel computing. If this argument is not provided, at least half the number of availabe cores will be used.
filename	character. Output filename of the averaged data. If this argument is not provided, result will not be written to disk.
stat	character. Currently only works with mean.

Value

A dataframe with temporal values averaged over the specified area.

Examples

files <- list.files(paste0(system.file(package="processNC"), "/extdata"),
                    pattern="tas.*\\.nc", full.names=TRUE)
cellstatsNC(files, startdate=2000, enddate=NA, cores=1)
