Write or Append Variables to a NetCDF File

This function creates a new NetCDF file or opens an existing one, then writes the provided variables, dimensions, and associated attributes.

Usage

write_netCDF(
  var_list,
  var_attr,
  xdim,
  ydim,
  tdim,
  xattr,
  yattr,
  tattr,
  fillvalue = 1e+32,
  compression,
  out_file
)

Arguments

var_list

A list of variables to write to the NetCDF file.

var_attr

A list of variable attributes. Each element in the list corresponds to a variable in `var_list` and contains its metadata (e.g., units, descriptions).

xdim

A numeric vector representing the x-dimension values (e.g., longitude).

ydim

A numeric vector representing the y-dimension values (e.g., latitude).

tdim

A numeric vector representing the time dimension values.

xattr

A named list of attributes for the x-dimension (i.e., `name` ,`long_name`, `units`, `axis`).

yattr

A named list of attributes for the y-dimension (i.e., `name` ,`long_name`, `units`, `axis`).

tattr

A named list of attributes for the time dimension (i.e., `name` ,`long_name`, `units`, `axis`, `calendar`).

fillvalue

A numeric value to represent missing or undefined data. Defaults to `1e32`.

compression

An integer specifying the level of compression to apply to the NetCDF file (typically 0-9).

out_file

A string specifying the path to the NetCDF file. If the file exists, the function opens it to append variables; otherwise, it creates a new file.
