The entire risk as to the quality, accuracy and performance of the climate change weather data calculated with this tool is with you. Files generated with this tool may not be distributed to a third party. The user of this tool takes the sole responsibility of complying with the terms and conditions of the original weather data as well as the climate change scenario data used within this tool. Therefore, generated weather files can only be used by persons or entities who possess the corresponding licensed weather files. The original weather files used for generating climate change adapted weather data may be copyrighted material.
The calculation routines underlying the CCWeatherGen and CCWorldWeatherGen tools are detailed in a technical reference manual: It is highly recommended to read the manual before using the tool. Please click the link below, unzip the file, run the executable and follow the instructions on the screen.Īll instructions required for CCWorldWeatherGen are given in the user manual.
In the meanwhile please use the 2003, 2007 or 2010 version of Microsoft® Excel for weather data conversionĬCWorldWeatherGen is provided as a self-extracting file within a zip file. Please note that the tool does not currently work with the 2013 version of Microsoft® Excel.

Publicationsĭetails on the underlying methodology used in CCWorldWeatherGen can be found in the following publication: For sites in the UK it is recommended to use the CCWeatherGen tool instead, as this uses more detailed Regional Climate Model (RCM) data. Therefore, CCWorldWeatherGen users are requested to familiarise themselves with the IPCC assessment reports to appreciate limitations and handle uncertainties of the climate change weather data generated with this tool. The CCWorldWeatherGen tool uses coarse General Circulation Model (GCM) data. However, it is solely distributed WITHOUT the required baseline weather files and/or climate change scenario data! (Please view sections 2.1 and 2.2 of the CCWorldWeatherGen Manual for information on where to obtain the required baseline data.)
The tool is made available free of charge.
You can produce ‘morphed’ EPW and TMY2 files as well as present-day TMY2 files from the original EPW format files. The CCWorldWeatherGen tool allows you to generate climate change weather files with a few mouse clicks.
It builds on previous work by the Sustainable Energy Research Group on climate change transformation of UK weather data (4) (see also the web pages on the CCWeatherGen tool). The underlying weather file generation routines of this tool are based on the so-called ‘morphing’ methodology for climate change transformation of weather data, which was developed by Belcher, Hacker and Powell (3). The tool is Microsoft® Excel based and transforms ‘present-day’ EPW weather files into climate change EPW or TMY2 weather files which are compatible with the majority of building performance simulation programs. It uses Intergovernmental Panel on Climate Change ( IPCC) Third Assessment Report model summary data of the HadCM3 A2 experiment ensemble which is available from the IPCC Data Distribution Centre ( IPCC DDC) (1,2).
The climate change world weather file generator (CCWorldWeatherGen) allows you to generate climate change weather files for world-wide locations ready for use in building performance simulation programs.
