Note
Observed values for current month are estimated from SYNOP reports. Previous months are constructed using data directly from available HadUK-Grid daily data.

Method (for estimated values only)
  • Mean 24 hour rainfall is calculated using available SYNOP reports over the appropriate region
  • An adjustment is applied (based on past 10 years of historical data), to bring this estimated mean closer to the daily figure calculated on HadUK_Grid
To calculate the anomalies, the 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 HadUK-Grid
