Major volcanic eruptions, as one of the natural forcing, increase sulfate aerosols in the stratosphere. The stratospheric aerosol forcing differs from tropical and extratropical eruptions, and depends on the eruption season and height, and volcanic volatile injections. In order to study different aerosol forcing and their impact, we perform simulations based on the fully coupled Community Earth System Model version 2 (CESM2) with the Whole Atmosphere Community Climate Model version 6 (WACCM6) with prognostic stratospheric aerosol and chemistry. Explosive eruptions at 14.6 N and 63.6 N in January and July injecting 17 Tg and 200 Tg SO2 at 24 km with and without halogens are simulated, in line with Central American Volcanic Arc and Icelandic volcanic eruptions. Simulated changes in the stratospheric sulfate and halogen burdens, and impacts on aerosol optical depth and ozone are analyzed.
