High-Latitude, Low-Altitude SAI: Overview of G6-1.5K-HiLLA Simulations in E3SMv3

Summary

This document addresses the challenge of mitigating rising global temperatures through geoengineering. It details a novel approach to Stratospheric Aerosol Injection (SAI) that simulates injections at high latitudes and low altitudes, which is more aligned with current aviation capabilities, unlike previous idealized models. The project is currently in progress, with initial simulations showing promising results in maintaining the 2020-2039 climatic state for 60 years, though further research and model comparisons are needed.
