Weather data is sourced directly from the BoM and reformatted as an RSS feed suitable for displaying on very small screen devices, such as the Gigaset C610 IP telephone handset (configuration details).
The feeds are limited to Australian states for which the BoM provides XML data.
Feeds will use content negotiation to return the preferred format - XML, RSS, Atom or Json. You can override negotiation by specifying a parameter in the query string eg. ?atom=true or ?json=true
This service is provided by David Gardiner. It is currently hosted on a free Windows Azure website, so should it become wildly popular there is a chance access could be limited.
Feel free to contact me via my blog or email if you have any questions or feedback.
