We describe a generalised downscaling and data generation method that takes the outputs of a General Circulation Model and allows the stochastic generation of daily weather data that are to some extent characteristic of future climatologies. Such data can then be used to drive any agricultural model that requires daily (or otherwise aggregated) weather data. The method uses an amalgamation of unintelligent empirical downscaling, climate typing and weather generation. We outline a web-based software tool (http://gismap.ciat.cgiar.org/MarkSimGCM) to do this for a subset of the climate models and scenario runs carried out for the 2007 Fourth Assessment Report of the Intergovernmental Panel on Climate Change. We briefly assess the tool and comment on its use and limitations.
► Most climate model outputs need manipulation before they can be used by agricultural modellers.
► We describe a tool to generate daily data that are somewhat characteristic of future climates.
► The method uses an amalgamation of empirical downscaling, climate typing and weather generation.
► The web-based tool provides downscaled data that can be used directly for agricultural modelling.
