Brief Initial Description
This workshop solicits contributions to address the combination of space- and ground-based observations and models and simulations to address global-scale ionosphere/thermosphere/mesosphere science questions. Three major global themes that have been suggested are: (1) Mass Exchange (including transport from high to low latitude, ion outflow, etc), (2) Electrodynamic Coupling (including conductance effects, the aurora, etc), and (3) Chemical Dynamical Coupling (including coupling from above and from below). Our goal is to articulate the principal outstanding issues in ionosphere-thermosphere-mesosphere research and define techniques and measurement programs we can use to address them. Combining observations from satellite instruments with those from ground-based instruments has been a very powerful method for the study of aeronomy. Since the early 1970s when all-sky camera data were used in conjunction with images of the aurora from the DMSP satellites, the strengths of the two techniques have been combined to gain a greater understanding than could be achieved by either observation in the absence of the other. The goal of this two part session is to examine specific coordinated satellite/ground-based research concepts to assist the NSF regarding possible future programs. It is clear that addressing the outstanding global science issues of aeronomy will require global-scale coordinated measurement programs. The first session will focus on the outstanding global issues and the observations required to address them. The second session will focus on the measurement techniques available for obtaining the observations on a global scale. We will specifically emphasize combining satellite missions with ground-based instruments to better understand the spatial-temporal aspect of the global system. While each has limitations and strengths, combining the two can greatly enhance the scientific return. Modeling can further assist in the synthesis and to develop a better understanding of the dominant physical processes apparent in the data. We also seek contributions from the modeling community specifically addressing their need for a better understanding of inputs and constraints on the models such as specification of boundary conditions in the models.
