大气化学是由光解反应驱动的，这使得它们的模型成为大气模型的关键组成部分。我们描述了Fast-JX的实施和验证，这是一种最先进的相互光解模型，进入MetUM化学-气候模型。这样就可以计算对流层中相互作用的光解速率，并通过计算除臭氧之外的云和气溶胶，增加了平流层中相互作用光解速率的计算。为了证明这种新的光解方案的有效性，我们采用了新的方法来验证模型，包括对模型进行采样以与飞行轨迹和卫星数据进行比较的技术。
Atmospheric chemistry is driven by photolytic reactions, making their modelling a crucial component of atmospheric models. We describe the implementation and validation of Fast-JX, a state of the art model of interactive photolysis, into the MetUM chemistry-climate model. This allows for interactive photolysis rates to be calculated in the troposphere and augments the calculation of the rates in the stratosphere by accounting for clouds and aerosols in addition to ozone. In order to demonstrate the effectiveness of this new photolysis scheme we employ new methods of validating the model, including techniques for sampling the model to compare to flight track and satellite data.
