United Kingdom: climate changes in the 21st century Dr.T.D.Mitchell, Tyndall Centre (www.tyndall.ac.uk), May 23 2002 The data are from 9 state-of-the-art GCMs reviewed by the IPCC (2001). The values are the changes between 1961-90 and 2070-99. The two variables are temperature (T,degC) and precipitation (P,%). There are 2 SRES emissions scenarios (A2,B2) and 2 seasons (DJF,JJA). Dr. Richard Jones (Hadley Centre) interpolated the original GCM data onto a common grid (144*73). Dr.T.D.Mitchell regridded these data (720*360) and aggregated the land grid-boxes into countries.
