Our goal is to extend the scope of the C/NOFS program to investigate the physical connections between the ion and neutral gases that lead to and promote the growth of equatorial plasma structure. Understanding these interactions extends far beyond the specific problem of determining when equatorial ionospheric structure will appear and into fundamental understanding of dynamo processes and momentum exchange that are important in all planetary environments where charged and neutral constituents have different mobility. We wish to address two important questions related to ion-neutral interactions and their influence on the generation and evolution of ionospheric structure.

What are the relationships between the behavior of F-region neutral winds
and the daily variability of ExB drifts ?

How do F-region neutral winds and ExB drifts influence the evolution of irregularities ?
