First super quick WIP results in these plots, inspired by MacDougall et al. 2020:

Results look comparable except for the UK-ESM model, need to see why that is. For reference the ZEC_50 numbers:

CESM2	MPI-ESM1-2-LR	CanESM5	ACCESS-ESM1-5	UKESM1-0-LL
-0.3111508	-0.2699858	-0.120552465	-0.0030308773	0.43511

Edit: I suppose the run could be newer, v20200106 when the paper was submitted at the end of 2019

@ChrisJones-MOHC Are these the plots you would like to have for ZEC in the REF? Will there likely be some ensembles so I should make it possible to use these as ranges?

OFFICIAL Hi Tina - can we switch to email? I don't use github much and maybe would have missed this. Can you clarify what the driver for this is? And where these came from? As you say, UKESM is wrong, so not sure what the calculation was to get this. We don't want these in the REF from the 1% and zecmip ruins, as those won't exist anymore, so we'll use the flat10 ones. I think if you are planning any science analysis for the REF it needs discussion - I thought it was more about evaluation.
