Azari, A. R., Jia, X., Liemohn, M. W., Hospodarsky, G. B., Provan, G., Ye, S. ‐Y., et al. (2019). “Are Saturn’s Interchange Injections Organized by Rotational Longitude?” Journal of Geophysical Research: Space Physics, 124. doi:10.1029/2018JA026196.
This work investigated if mass transport events most similar to Rayleigh-Taylor instabilities in Saturn’s space environment were related to ionospheric or upper atmopsheric conditions by purusing a large-scale data occurrence analyses to tease apart multiple dependencies.

Featured article in July 2018 for novel interdisciplinary visualizations. The work within this paper developed a physics-based method most similar to logistic regression to rank and classify transient of energetic material around Saturn (interchange injections). This created the first standardized comparison to several statistical surveys undertaken to understand the transport of mass around Saturn. Can be found online at JGR Space Physics.
