About the Role

Conduct research using observations from NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission to improve understanding of coronal mass ejection (CME) propagation, solar wind evolution, and heliospheric structure. Research activities include the analysis of PUNCH polarization observations to develop methods for determining the three-dimensional location and structure of solar wind features. A separate project will involve the comparison of Solar Dynamics Observatory/Helioseismic and Magnetic Imager (SDO/HMI) magnetograms against simulation results of low-frequency MHD waves. Research is directed by an NCAR staff scientist and includes pre-defined research objectives and deliverables.
