parse_metar_file#
- metpy.io.parse_metar_file(filename, *, year=None, month=None)[source]#
Parse a text file containing multiple METAR reports and/or text products.
- Parameters:
filename (str or file-like object) – If str, the name of the file to be opened. If filename is a file-like object, this will be read from directly and needs to be opened in text mode (i.e.
read()needs to return a string, not bytes).year (int, optional) – Year in which observation was taken, defaults to current year. Keyword-only argument.
month (int, optional) – Month in which observation was taken, defaults to current month. Keyword-only argument.
- Returns:
Notes
The output has the following columns:
