Observed Temperature Data
The observed temperature data were based on gridded data sets produced by the Climate Research Unit of the University of East Anglia and the Hadley Centre of the British Meteorological Office. The file used was “crutem3v.dat” downloaded from http://www.cru.uea.ac.uk/cru/data/temperature/
The data preparation is described in P. Brohan, J.J. Kennedy, I. Harris, S.F.B. Tett and P.D. Jones, “Uncertainty estimates in regional and global observed temperature changes: a new dataset from 1850”. J. Geophys. Res, 111, D12106, doi:10.1029/2005JD006548. (Copyright 2006 AGU).
The files we used have average values for the relevant grids with available data weighted by the cosine of the latitude to take account of the diminishing area of grid remote from the equator.
Simulated Temperature Data
The simulations were based on the 20c3m scenario in which experiments were run with greenhouse gasses increasing as observed through the 20th century. The files contain monthly simulations. They were downloaded from http://climexp.knmi.nl
. The abbreviations of the modelling centres are given in the above table. The file name also includes an abbreviation of the model name and the geographical range.
The simulated temperature data for comparison are based on the following .dat files, which can be viewed by clicking the three bar icon
