SSN tau=5y relaxation vs CET

A relaxation to equilibrium response to SSN is calculated by convolution with a exponential decay with time-constant : tau = 5 years

Central England Temperature index is filtered with a 10y low-pass filter to attain similar degree of short term variability.

A similar comparison to hadSST3 is here:
