Output formats and available elements

Output formats depend on the requested data. Magnetic variation data is usually provided as IAGA-2002 ascii format. K values (available only at WIC) are provided in dpk format. Meteorological data will be obtained in a comma separate ascii format. Meta information will always be provided as json. Except for meta information output formats can be forced into either CSV or json by using the format option.
Example: of=iaga2002, of=ascii, of=json, of=csv
