Grand ensemble of climate simulations over the last Millennium with general circulation models and their future projections

In order to test the performance of various climate simulations by full-featured general circulation models and to improve the prediction of the future climate, we have performed an ensemble of numerical simulations of the climate change over the last millennium using variants of the third generation Hadley Centre climate model. The grand ensemble of model runs are constructed by taking different initial conditions, external forcing scenarios, and internal parameters of the model itself. The model runs are then computed by volunteer computing infrastructure of ClimatePrediction.net over the internet on a variety of computing platforms.
