Don Banfield

Senior Visiting Scientist, CCAPS


Don Banfield is an expert in the dynamics and structure of both giant and terrestrial planet atmospheres. He has used ground-based and spacecraft-based observations, theory and modeling to understand planetary atmospheres. He has participated in planetary missions from Voyager II, Galileo, Mars Polar Lander, Mars Exploration Rovers (MER), Mars Reconnaissance Orbiter, through to InSight and Mars2020. He is currently developing the next generation of instruments for the in situ study of terrestrial planet surface-atmosphere interactions, and planetary atmospheres in general. He currently serves as the Goals Committee Chair of MEPAG (Mars Exploration Program Analysis Group)."
