UKCP09: Gridded data sets of monthly values

Monthly data are in multi-year blocks, with each monthly file name following the convention:

Variablename_yyyy-mm_Actual.txt

where yyyy is the year, mm is the month number, and 'Actual' indicates a grid of actual values (rather than, say, anomalies). Each zipped data block is selected by clicking on the table below.
