Towards an All-Inclusive Earth System model (TIES): Merging lower, middle and upper atmospheric models to study solar effects

我们星球环境中的过程受两个主要驱动因素支配：低层和中层大气的变率主要受源自地表的过程的影响，而高层大气的变率则受太阳变率的控制。传统上，不同的数值模式被用于研究这些区域，尽管它们既不是明显的区域，也不是完全独立的驱动因素。来自低层大气的波可以对高层大气产生很大的影响，而太阳的变化至少会对平流层中部产生严重的影响。TIES项目的目的是弥合气象学和空间科学之间的差距，因为这种大气耦合只有在一致地描述所有相关区域的模式中才能被捕捉和理解。将两个模型结合在一起，很好地描述低层、中层和高层大气，从而创建一个创新的全大气模型。这个工具将用于研究太阳变化对大气的影响。科学重点将放在粒子降水产生的消耗臭氧的NOy物种及其与极性化学和动力学的相互作用，以及通过大气波的垂直耦合传递太阳信号。来自其他CAWSES项目（ARTOSAIMOS, ProSECCO）的专业知识和数据将有助于这些调查。

The processes in the environment of our planet are governed by two major drivers: The variability of the lower and middle atmosphere is mostly influenced by processes originating at the surface, while the variability of the upper atmosphere is controlled by solar variability. Traditionally different numerical models have been used to study these regimes, although they are neither distinct regions nor completely independent drivers. Waves from the lower atmosphere can have large effects in the upper atmosphere, and solar variability can have severe effects at least down to the middle stratosphere. The aim of the TIES project is to bridge the gap between meteorology and space science because such atmospheric coupling can only be captured and understood in models describing all involved regions consistently. An innovative whole atmosphere model will be created by coupling two models that in combination very well describe the lower, middle and upper atmosphere. This tool will be used for investigations of the impact of solar variability on the atmosphere. Scientific focus will be on ozone depleting NOy species that are produced by particle precipitation and their interactions with polar chemistry and dynamics, as well as the transfer of the solar signal through vertical coupling by atmospheric waves. Expertise and data from other CAWSES projects (ARTOSAIMOS, ProSECCO) will aid these investigations.
