Since then it has been placed within a circular low turf wall enclosure of 3 m diameter on the ground, which is considered to provide a suitable environment for accurate measurements of rainfall. The wall is 0.45 m high, with steep internal and sloping external sides. The remaining 2 gauges have been on the ground for the duration of the measurements. The Sparsholt multiple gauge files contain standard drop-counter gauge data and tipping-bucket gauge data.",
