The Hadley Centre Global Environmental Model version 3 at the Global Coupled model 2.0 (HadGEM3 GC2) configuration (Williams et al 2015). HadGEM3 GC2 has atmospheric resolution of 0.83° longitude by 0.55° latitude (about 60km at mid-latitudes), with 85 atmospheric levels, and an ocean resolution is 0.25° with 75 quasi-horizontal levels. The simulations are all prescibed with preindustrial CO2 and a 1850 climatological estimate of ozone.

Each set is from the same initial conditions (ocean and ice initial conditions from the HadGEM3 GC2 simulation anude, year specified below)
Experiment set 1 is comprised of:
CONTROL EXPERIMENT (C)
TSI = 1361
LOWERED TSI EXPERIMENT (T)
TSI lowered by 0.5
UV PERTURBATION EXPERIMENT (U)
TSI lowered by 0.5 plus P, UV lowered by P
COMPENSATION UV PERTURBATION (P).
TSI lowered by 0.5, UV lowered by P, Compensatory increase in other spectral bands by total of P
Experiment sets 2-4 are comprised of C, U and P, and experiment sets 5? 8 are comprised of C, T and U.
