The PI will investigate the persistence of enhanced ammonia in the jovian stratosphere. Their observations of Jupiter derive vertical and horizontal distributions for ammonia. In addition, they will complete the radiative transfer analysis of the hydrogen cyanide images. The vertical distributions derived will be compared with ammonia and carbon, two molecules of different impact-induced origin. The horizontal coverage will be compared to the dust observed to investigate whether the particles were coupled with the gas in the dynamics following the impact. Finally, their re- observation of Jupiter will be to image hydrogen cyanide, which is stable for over a year, and therefore a good tracer of atmospheric dynamics.***

PI将调查木星平流层中氨气的持续增强。他们对木星的观测得出了氨的垂直和水平分布。此外，他们将完成氰化氢图像的辐射转移分析。得到的垂直分布将与氨和碳这两种不同撞击成因的分子进行比较。水平覆盖范围将与观测到的尘埃进行比较，以调查颗粒在撞击后的动力学中是否与气体耦合。最后，他们对木星的重新观测将是氰化氢的图像，氰化氢在一年多的时间里是稳定的，因此是大气动力学的一个很好的示踪剂
