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.
