Met Éireann’s Weather Observation Network

Met Éireann has an observation network that gathers weather data across the country for use in weather forecasts, aviation, marine, agriculture, climate analysis, forecast verification and meteorological research. All weather observations record day-to-day changes of the atmosphere and are quality controlled and archived in Met Éireann’s database to formulate long-term climate records.

Met Éireann currently uses four different types of weather station to record data, all differentiated according to the range of instruments and measurement interval.
