R Documentation

Create empty netCDF file for one or more thermistor chains

Description

Creates a netCDF file with specified dimensions. The file has no data within it, but must be added in afterwards. Thermistors should may have different measurement depths but should have the same number of measurement depths (levels)

Usage

createGenericNCDF(
  file,
  n_stations,
  n_timestep,
  n_levels,
  close_file = FALSE,
  time_units = "days since 1970-01-01 00:00:00"
)

Arguments

`file`	character, path to output netCDF file (*.nc)
`n_stations`	integer, how many sites are to be added to the file
`n_timestep`	integer, the number of unique timesteps for which there is temperature data
`n_levels`	integer, the largest number of depth measurements in any profile
`close_file`	logical, whether or not to close the connection to the file after creation. Leaving the file open allows for the immediate addition of data. Defaults to FALSE.
`time_units`	netcdf4-style string description of time units

Details

The file structure is based on H.5.1. "Multidimensional array of time series profiles representation of time series" (http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html#_multidimensional_array_representations_of_time_series_profiles) * Depth values are not time-dependent, therefore the depth levels of a station must not change between time periods
