By reflecting some incoming solar radiation, stratospheric aerosol intervention using SO2 would reduce global mean temperature. Previous research has shown that multiple injection latitudes can be used to maintain not only global mean temperature, but also interhemispheric and equator-to-pole temperature gradients. However, the regional climate response depends not only on where the SO2 is injected, but also on when. The differential outcomes highlight the potential for underlying trade-offs, with different choices regarding deployment leading to a different distribution of benefits or harms. Here we present simulations results obtained by injecting in only one season instead of continuously throughout the year to show how they results in significant differences in regional climate, even when the same global objectives and the same choices of latitudes is maintained. This dataset supports these described conclusions.
