Heliophysics Science: Experimental and Interdisciplinary Space Plasma Physics

Responsibilities Recent work focuses on three major thrusts and an Associateship application in one or more areas is of great interest. The first is ongoing work to develop satellite‑based plasma mass spectrometer instrumentation. Recent work has focused on technological innovations to measure positive and negative species with the same subsystem, and the use of carbon foils and solid state detectors to discriminate species by mass. Low‑resource optimization is a goal as well as adaptation for planetary or high‑radiation space environments. The second thrust is on analysis of recent measurements from such instrumentation. Recent work has focused on the effect of wave‑particle interactions on the radiation belt populations, and the importance of ionospheric outflow and oxygen in particular to the storm‑time dynamics of the inner magnetosphere. Also of interest is the role of magnetic field mapping in connecting in situ processes in the magnetosphere and ionosphere. Ongoing research with the HOPE instruments on the Van Allen Probes would be especially welcome and could be focused on evolving scientific or instrument response understanding. Lastly, a recent topic of much interdisciplinary interest is the Aurorasaurus platform. Aurorasaurus.org is a citizen science website and mobile application we are developing to improve space weather forecasting in this, the first solar maximum with social media. Citizen science reports and ad‑hoc tweets about the visibility of the Northern Lights represent an important, new real‑time network of ground truth observations. Ongoing work to improve the capability to now‑cast visibility of aurora for the public using this tool is of great interest to the space science and human‑computer interactions fields.
