of these processes can disrupt the inner eyewall’s overturning circulation, and thus lead to its collapse. Yet the relative role of each process remains unclear. Detailed observations of an eyewall replacement cycle at all stages are crucial for advancing knowledge of their underlying dynamics. Yet, such observations are limited by the planning and resources needed to deploy instruments and platforms capable of useful data collection. In October 2014, observations were collected of Hurricane

Dust Impacts on the 2012 Hurricane Nadine Track during the NASA HS3 Field Campaign. 2015 ; Randles et al. 2017 ; Buchard et al. 2017 ). Additionally, Nowottnick et al. (2015) describes the GEOS-5 lidar signal simulation capability. Owing to these forecasting and data assimilation capabilities, GEOS-5 forecasts were a valuable resource for guiding mission operations and flight planning involving dusty SAL outbreaks during HS3, and the same modeling system forms the basis of the subsequent scientific analysis presented here. Aerosols are simulated in GEOS-5 with an online
