Weather observations are among the most important data required to enable London and cities around the world to function. They have an enormous range of uses – they are used by everyone to know when to take an umbrella or wrap up warm, but they are also critical for transport, businesses and government.
London has a surprising amount of weather data – about 260 stations that measure some aspect of London’s atmosphere, including rainfall, temperature and air quality. These are operated by a wide range of organisations and individual volunteers, however, there is a general consensus that:
Observing London makes the case that we could and should harness this wealth of information, most notably through the creation of a focused weather portal for London.
Improving the quality and access to weather data helps us to better understand and adapt to current and future conditions, ensuring London is a resilient and thriving city. Such improvements would also lead to new applications yielding economic benefits. This has been the experience of other cities such as Shanghai, Helsinki and Birmingham. London has the opportunity to learn from these cities and develop leadership in this area internationally.
In the report a proposal is made for a London Climate Data Portal (LCDP). Whilst developing the portal, LCCP are gathering support from organisations to make weather data free and accessible to the public.
