Tom Bown, a volunteer from Anglesey in Wales, has been measuring rainfall at the same location on the island for 75 years.

Bown, 85, has recently been recognised by Natural Resources Wales (NRW) and the Met Office for his tireless work providing valuable data for climate study. He has measured rainfall at Llwydiarth yr Esgob Climate Station in Llannerchymedd at 9:00 am every morning since 1958.

Mr Bown was awarded with a storm glass weather predictor, and a plaque to highlight his 75th anniversary.

Bown uses a Casella Daily Storage Rain Gauge to record daily precipitation, which is critical for various purposes such as trend analysis and flood warning services. His long-term data collection is highly valued by scientific bodies.

The detailed weather records from Llwydiarth yr Esgob Climate Station, founded in 1908, have been crucial for trend analysis, water balance calculations, and flood warning services.

“The Met Office, NRW and other scientific bodies are reliant on high-quality data to do much of their work. We depend on reliable volunteer observers to collect some of this data.

"To record over a century's worth of data from one site is rare and valuable. However, for one person to have done the readings for 75 of those years is remarkable," said Stuart Herridge from the Met Office.

“We are extremely grateful to Mr Bown for his commitment and hard work. The scientific community is in a better position thanks to the work carried out by such committed volunteers," he added.

Tom Bown's remarkable commitment highlights the importance of reliable volunteer observers in providing high-quality climate data.
