Headline indicators
Where this number comes from
Source: Met Office — HadUK-Grid gridded climate observations, HadUK-Grid areal series, Rainfall, Northern Ireland, annual. Licence: Open — attribution required (attribution required).
Method: Met Office published area-average total precipitation, from the HadUK-Grid 1 km gridded analysis of the national rain gauge network. Gauge density is far lower in the nineteenth century than today, and mountain precipitation is systematically under-measured, so early values carry greater uncertainty than recent ones.
