Write the interpolator object

Write the interpolator object to a file

write_interpolator(interpolator, filename, .overwrite = FALSE)

Arguments

interpolator

meteoland interpolator object, as created by create_meteo_interpolator

filename

file name for the interpolator nc file

.overwrite

logical indicating if the file should be overwritten if it already exists

Value

invisible interpolator object, to allow using this function as a step in a pipe

Details

This function writes the interpolator object created with create_meteo_interpolator in a NetCDF-CF standard compliant format, as specified in https://cfconventions.org/cf-conventions/cf-conventions.html
