Analysis of UK precipitation extremes derived from Met Office gridded data

ABSTRACT In Simpson and Jones (2012) we introduced new, homogenized UK national and regional rainfall series derived from 5 km gridded daily and monthly precipitation data. The monthly series were extended back to 1766 for monthly England and Wales ( EW ) precipitation, to 1873 for monthly values fo...
