UKCP09: Regional averages

The data files are obtained by clicking on the links in the table below. Each text file contains the average values for each administrative region and for each river basin. Monthly variables have 12 values for each region (one for each month) whereas annual variables have just one value (the annual average). In April 2012 the files with the 1961-1990 averages were re-named, but not re-run.
