ENSEMBLES RT1: Description of perturbed parameters (seasonal-to-decadal)

 
 

 

The perturbed parameter approach is described in M. Collins, B. B. B. Booth, G. R. Harris, J. M. Murphy, D. M. H. Sexton and M. J. Webb, Towards quantifying uncertainty in transient climate change, Clim. Dyn., 27, 127-147,
doi:10.1007/s00382-006-0121-0. The list of parameters used in the reference (1503) and the eight perturbed members (1504) of the s2d ensemble is as follows:
