ftp_transfer

The ftp_transfer functions does as the name implies. It looks at the output_path on your local drive then compares it to the MetService ftp site and downloads what is on the ftp site that isn’t in the output_path. It can be loaded in from the basic module:

from nzmetservice import ftp_transfer

And feed it with the necessary parameters:

ftp_transfer(ftp_path, username, password, output_path)

You will likely want to create a scheduled task to run a script containing this function once an hour.

Selection and processing

The other two functions are simple selection and conversion tools.
