Sierra Leone: 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.
