How can weather data be obtained for sites outside the United Kingdom?

The Met Office can recommend a meteorological authority to provide weather data within the given country. Many countries have authorities similar to the Met Office where similar data is available. In other countries there may be little established data but it may still be possible, with the advice of the appropriate weather authority, to agree limiting values approximating to the ‘once in ten years’ average.
