Notes
Values are updated once per day, and are usually a couple of days behind the current date.
Data comes from the Met Office National Climate Information Centre, and can be found here.
The UK series is estimated from an area weighted combination of the England & Wales, Scotland, and Northern Ireland series.
For further details please see Alexander, L.V. and Jones, P.D. (2001) Updated precipitation series for the U.K. and discussion of recent extremes, Atmospheric Science Letters doi:10.1006/asle.2001.0025.
To calculate the daily anomalies, a pre-calculated climate is subtracted; this derived for each day by taking a 15-day rolling mean, centred about the day in question, of daily figures from the relevant rainfall series.
The regions used in the UKP series are shown below - the figures are derived from the average of numerous rain gauge measurements within each region, from sites with long-standing records.
