WCMO
We have a perfectly good Bureau of Meteorology in this country, which, along with UK's Met Office, USA's NWS and Japan's JMA, supply, combine, share and distribute weather data and outputs from predictive models all over the world.
The ABC news
website consumes weather data from NZ's commercial arm (MetraWeather) of their public Met service.
Those large data sets are sourced from the BoM anyway, and then curated and modelled for specific clients (Mining, shipping, construction etc). Those clients pay for the service. The BoM provides the same service anyway. I assume Metraweather just widens the scope with NZ/Pacific Island data where required (mind you, the JMA can supply that as well).
The data on the ABC's website is just bog standard localised weather data. There's nothing unique about it.
Why the hell do we pay a commercial company to provide standard data sets that are freely available from the BoM via an open API?
I must be missing something.
