The TRY/DSY weather file morphing methodology for generating climate change weather data developed by Belcher, Hacker and Powell (2,3) which formed the basis for this weather file generator tool is gratefully acknowledged. Special thanks go to Linda Lawrie and Drury Crawley for providing guidance on the appropriate ground temperature equations for generating EPW files. Furthermore the work of the following people / institutions that was key to compiling this weather file generator tool is also gratefully acknowledged: the ASHRAE psychrometric formulae (4), the TMY2 weather file manual by Marion and Urban (5), the EPW weather data description by Crawley, Hand and Lawrie (6), the all sky model for calculating downwelling longwave radiation by Crawford and Duchon (7), the models for calculating illuminance and sky luminance parameters from radiation data by Perez, Ineichen, Seals, Michalsky and Stewart (8), the Meteonorm weather software version 6.0 which was used to generate average monthly global horizontal radiation baseline data for the CIBSE/Met Office weather sites (9), the ground temperature equation by Kusuda and Achenbach (10), the paper on TRY / DSY file generation by Levermore and Parkinson (11), the optical air mass tables provided by Kasten and Young which were used for calculating illuminance and sky luminance parameters (12) and CIBSE Guide J which was used for calculating direct normal solar radiation (13).

The self extracting download file was generated using FreeExtractor v1.44 (14).

Aspects of this work were undertaken within the Sustainable Urban Environment (SUE) programme funded by the UK Government Engineering and Physical Sciences Research Council (EPSRC). Project: Innovation in Design, Construction & Operation of Buildings for People (IDCOP), Partners: ARUP, University of Greenwich, University of Reading, University of Southampton.
