Accordingly, the modeling community has undertaken concerted efforts in performing standard (comparable) simulations and making multimodel output available in publicly accessible archives like PCMDI's CMIP3 and soon to come CMIP5 (PCMDI 2009).

While the CMIP3 archive at PCMDI has proved invaluable to many climate scientists and impacts investigators, there remains a disconnect between the spatial scale of typical GCM output and the scales at which impacts are important to society and ecosystems.
This and our experiences with other climate impacts studies motivated a team of us to develop and distribute an easy-to-use downscaled climate projections resource, building on the GCM output at the widely used PCMDI archive and utilizing a well-tested and peer-reviewed downscaling technique.

The selection of which GCMs are used [e.g., output from over 20 GCMs was archived by the Program for Climate Model Diagnosis and Intercomparison (PCMDI) that were run for the IPCC AR4] has been based on a range of criteria, but often instead of model performance, the GCMs used have hinged upon model output availability at the time the study was conducted.
i) New climate change projections: PCMDI is now making available climate change simulations produced for the IPCC AR5.
PCMDI's archive of daily GCM output will make alternative downscaling methods more viable, but it will also require more evaluation of the appropriate applications of alternative approaches and how they relate to each other.
