Maura Hagan

	Maura Hagan, Director of ASP

During FY2006, Maura Hagan continued her dual role at NCAR as the Director of the Advanced Study Program (ASP) and Senior Scientist in the High Altitude Observatory (HAO).

Research Highlights:

Dr. Hagan continued to focus her HAO research efforts on the physics of the upper atmosphere, and in particular on the dynamical coupling between the lower, middle, and upper atmosphere and the electrodynamic coupling between ionospheric plasma and the neutral thermosphere. She contributed to a series of studies aimed at analyzing and interpreting atmospheric tidal signatures observed in the middle and upper atmosphere from both the ground and space. Dr. Hagan also co-authored a manuscript suggesting that deep convective activity in the tropical troposphere may be affecting the ionosphere via tidal effects on the E-region dynamo.
