The Meteorological Office have come up with a real corker of a weather map with their Invent service about which they say
Met Office Invent will showcase some of our future plans for presenting web-based weather forecasts, products and information. It will allow you to become involved in the formation of new weather and climate change products, services or forecasts.
There are one heck of a lot of options for different data to be displayed, adjusting the time of the forecast, storing your favourite locations and the interface is pretty neat. To cap it all you can download the weather data under a pretty liberal license, shame they couldn’t just use the Open Government License which is so easy to understand.
