* BETWIXT short summary *

In order to develop high-resolution climate change scenarios for key locations, BETWIXT will utilise computer-based weather generators to produce common source datasets for the other projects in the initiative. The basis for this additional data will be the UKCIP02 climate change scenarios, which will then be developed for shorter time periods and locations, to meet the particular requirements of the built environment. BETWIXT will also address issues of scenario uncertainty relating to key climate elements, and provide further information on potential changes in the "urban heat island" effect.

BETWIXT will act as a service to the other EPSRC/UKCIP projects in the initiative, and develop best practice in the application of climate change scenarios. At the end of the project, the new data generated will be made more widely available.
