EXPECT Double delta AER

Title EXPECT Double delta AER
Description EXPECT seasonal hindcast experiment Double delta AER. Doubles the annual rates of anthropogenic aerosol change after 1993 while leaving the ocean ICs unperturbed. (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 1993-2023 and run for 7 months.
