Computer simulations of past climate. Variables provided as model output are described by parameter keyword. In some cases the parameter keywords are a subset of all archived model output, and additional output is available upon request. Additional summary information can be found in the abstracts of papers listed in the data set citations. STUDY NOTES: These simulations were run by Dr Pearse J Buchanan of the ARC Centre of Excellence for Climate Systems Sciences, as part of his PhD in quantitative marine science.
