This work was undertaken with funding for MN from the U.K. Natural Environment Research Council (Grant No. GR3/09721) and MH from U.K. Department of the Environment, Transport and the Regions (DETR; Contract EPG 1/1/48). Data supplied by numerous national meteorological agencies, research organizations, and private individuals made this research possible and these contributions, while too numerous to mention by name, are gratefully acknowledged. The CRU precipitation, mean temperature, and diurnal temperature range datasets have been compiled over a number of years with support from the U.K. DETR and the U.S. Department of Energy. Mike Hutchinson kindly supplied the interpolation software. Wolfgang Cramer and David Legates generously provided the CRA and LEG datasets, respectively. Louise Bohn, David Lister, Nick Brooks, Chris Turney, Martin Airey, and Ian Harris all spent many hours on data entry and quality control. The Climate Impacts LINK Project (U.K DETR. Contract EPG 1/1/16) at the Climatic Research Unit provided computing facilities for this research. The comments of two anonymous reviewers resulted in improvements in the final version of the manuscript.
