EXPECT Constant CO2/ocean/ClimLand

Title EXPECT Constant CO2/ocean/ClimLand
Description EXPECT seasonal hindcast experiment Constant CO2/ocean/ClimLand. CO2 emissions kept constant at 1993 levels and warming footprint removed from ocean initial conditions (as Constant CO2/ocean iqe9), but additionally replaces land ICs with a constant climatology derived from ERA5 over 1983–2003 (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.
