(2023, part 1) and Bednarz et al. (2023, part 2): Climate response to offequatorial stratospheric sulfur injections in three Earth System Models. Here we present the results from the first systematic intercomparison of climate responses in three Earth System Models where the injection of SO$_2$ occurs at different latitudes in the lower stratosphere: CESM2-WACCM6, UKESM1.0 and GISS-E2.1-G. The first two, and a version of the third, use a modal aerosol microphysics scheme, while a second version of GISS-E2.1-G uses a bulk aerosol microphysics approach. Our aim is to determine commonalities and differences between the climate model responses in terms of the distribution of the optically reflective sulfate aerosols produced from the oxidation of SO₂, and in terms of the surface response to the resulting reduction in solar radiation. A focus on understanding the contribution of characteristics of models transport alongside their microphysical and chemical schemes, and on evaluating the resulting stratospheric responses in different models is given in Bednarz et al. (2022). The goal of this exercise is not to evaluate these single point injection simulations as stand-alone proposed strategies to counteract global warming; instead we determine sources and areas of agreement and uncertainty in the simulated responses and, ultimately, the possibility of designing a comprehensive intervention strategy capable of managing multiple simultaneous climate goals through the combination of different injection locations.en-USClimate engineeringgeoengineeringSolar Radiation ModificationSulfatedatasethttps://doi.org/10.7298/22cq-mx33
