A new version of the weather morphing tool is available (open, free, and cross-platform). Besides mathematically transforming EPW files to match future median projections of each timeframe, now, it also includes the generation of the warmest and coldest years of each timeframe.
This feature allows researchers to determine the bounds of each future projection and include the potential worst years of each timeframe to precent under dimensioning of energy systems.
