Selecting a climate model subset to optimise key ensemble properties

An efficient and versatile method that finds a subset which maintains certain key properties from the full ensemble is needed, but very little work has been done in this area. Therefore, users typically make their own somewhat subjective subset choices and commonly use the equally weighted model mean as a best estimate.

However, different climate model simulations cannot necessarily be regarded as independent estimates due to the presence of duplicated code and shared development history.
