该提案将确定二氧化硫（SO2）注入在产生有可能限制气候变化影响的辐射强迫方面的主要自由度。向平流层注入二氧化硫的能力将被添加到共同地球系统模型（CESM-WACCM）的全大气群落气候模型版本中，该模型是一个完全耦合的陆地、海洋、冰和大气模型，延伸到平流层，其中包括对流层和平流层化学的完整交互。该研究将得出最合理的注入位置，可以在设计良好的地球工程场景中用作自由度。

This proposal will identify the main degrees of freedom of sulfur dioxide (SO2) injections in creating radiative forcing that has the potential to limit the impacts of climate change. The capability to inject SO2 in the stratosphere will be added to the Whole Atmosphere Community Climate Model version of the Community Earth System Model (CESM-WACCM), a fully coupled land, ocean, ice, and atmospheric model extending through the stratosphere, which includes full interactive tropospheric and stratospheric chemistry. The study will derive the most reasonable injection location(s) that can be used as degrees of freedom in a wel-designed geoengineering scenario.
