The National Academies of Science recommended in 2015 that more research be undertaken to understand solar geoengineering, that is, approaches such as stratospheric aerosol injection that would cool the climate by reflecting some sunlight back to space. Introducing a design element into solar geoengineering research provides a critical shift in perspective that will fundamentally alter the conversation surrounding geoengineering, and inspire further research. Only recently have models been able to simultaneously capture the full coupling between aerosol microphysics, chemistry, and stratospheric dynamics. By taking advantage of this state-of-the-art capability, this research will enable a better assessment of what can and cannot be achieved through an intentionally designed stratospheric aerosol injection strategy. It is plausible that temporary and limited geoengineering deployment could be used to reduce climate risks, but making such an assessment requires understanding projected impacts. This research aims to take a major step forwards towards that objective by developing a well-designed strategy based on an exploration of the design space. This is essential to ensure that future decisions regarding these approaches are well-informed. Furthermore, the multidisciplinary perspective gained by applying engineering optimization, dynamic systems, and feedback design to climate science provides an opportunity to broaden both communities with the potential to spark additional insights and research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

美国国家科学学院在2015年建议进行更多的研究来了解太阳能地球工程，即平流层气溶胶注入等方法，通过反射一些阳光回太空，可以冷却气候。将设计元素引入太阳能地球工程研究中，可以在观点上进行批判性转变，从根本上改变了围绕地球工程的对话，并激发了进一步的研究。直到最近，模型才能够同时捕获气溶胶微物理，化学和平流层动力学之间的完整耦合。通过利用这种最新能力，这项研究将可以通过有意设计的平流层喷射策略来更好地评估可以和无法实现的目标。可以使用临时和有限的地球工程部署来降低气候风险是合理的，但是进行这样的评估需要了解预期的影响。这项研究旨在通过基于对设计空间的探索制定精心设计的策略来迈向这一目标。这对于确保对这些方法的未来决策具有很好的信息至关重要。此外，通过将工程优化，动态系统和反馈设计应用于气候科学获得的跨学科观点为扩大两个社区提供了机会，并有可能激发更多的见解和研究。这一奖项反映了NSF的法定任务，并通过该基金会的知识优点和广泛的影响来评估NSF的法定任务，并被认为是值得通过评估的支持。
