The tipping bucket raingauge is particularly suitable for the automation of rainfall measurement but it does not perform well in freezing conditions. It is based on a small container or bucket which, when filled with rain, tips and empties while recording the event electronically. The size of bucket used widely across the UK network holds 0.2 mm of rain. A larger 0.5 mm bucket is in use at some Environment Agency stations though only those at some remote or high level locations send readings to the Met Office. Bucket tip times may be stored directly by a data logger (such as the Met Office SSER system in use since the early 1980s) or converted locally to a rainfall accumulation by systems such as SAMOS, ESAWS or CDL.
