  • Precipitation networks

    The Atmospheric Environment Service has no network density limitations for stations reporting precipitation. As general guidance it is suggested that gauge separations should be about 15 miles (24 kilometres) in rural areas; a higher density is desirable in more heavily populated areas, and in...
