Solar Wind-Magnetosphere Interactions and Space Weather

CO-CHAIR
MARY K. HUDSON is professor of physics at Dartmouth College where she also served for 8 years as chair of physics and astronomy. Dr. Hudson was one of the principal investigators with the NSF-funded Center for Integrated Space Weather Modeling, where researchers study the weather patterns that originate from a solar eruption, following the energy and mass transfer through the interplanetary medium, all the way to the Earth’s ionosphere. Current areas of investigation include the evolution of the radiation belts; how the ionized particle outflow known as the solar wind and the magnetic field of the Sun interact with the magnetic field of the Earth, producing electrical currents in the ionosphere; and the effects of solar cosmic rays on radio communications near the Earth’s poles. She is a co-investigator on NASA’s Radiation Storm Belt Probe Mission. Dr. Hudson is also funded by NASA’s Supporting Research and Technology program, studying related effects of the Earth’s space radiation environment, which can affect both astronaut safety and satellite systems. Her research includes modeling sudden changes in relativistic electron fluxes and solar cosmic rays at and inside the 24-hour orbital period of many communication and navigation satellites, the effects of global oscillations of the Earth’s magnetic field, and associated changes in solar wind conditions that have their origins at the Sun. She has served as chair of the NSF Geospace Environment Modeling Program and she gave the American Geophysical Union (AGU) Van Allen Lecture in 2006. She is also the recipient of the American Institute of Aeronautics and Astronautics James A. Van Allen Space Environments Award for 2012.
