Sulfur is injected continuously at the equator in the constant strategy while the injection area is varied spatially and temporally in the varying strategy. Injection magnitudes between 2 - 100 Tg(S)yr\u22121 are simulated with EC-Earth3 using aerosol modules M7 and SALSA. CO2 compensation capacities of both strategies are also considered. The varying strategy was found to produce a stronger radiative forcing and smaller precipitation due to the fast precipitation response compared to the constant strategy above 10 Tg(S)yr\u22121 injection rates. Aerosol fields simulated with SALSA produced stronger radiative forcing compared to M7 in majority of the scenarios, however no clear trend was observed in fast precipitation response in terms of aerosol module.
