EXPECT Double delta CO2/ocean/AER

Title EXPECT Double delta CO2/ocean/AER
Description EXPECT seasonal hindcast experiment Double delta CO2/ocean/AER. Doubles the forced pattern of climate change in the ocean ICs after 1993 and doubles the annual rates of both CO2 increase and anthropogenic aerosol change after 1993. (For full details see Mayer et al. 2026). Experiment uses Cy49R2 v8 at Tco199 and ORCA025Z75 resolution (the reference ocean ICs are from ORAS6 0001). 51 member ensemble of May initialisations for the years 1993-2026 and run for 7 months.
