Delving into the Chromosphere: New Observational Tools

The chromosphere lies at the boundary between the near-equilibrium photosphere and the hot, expanding corona. This region combines both large interconnecting magnetic structures, and fine-scaled dynamics into an intriguingly complex whole. Studying this behavior is a significant observational challenge, requiring sizable fields of view (60-90") sampled at high spatial (< 0.3") and temporal resolution (< 30 seconds), with full spectral information in multiple lines. We will describe how instruments based on Fabry-Perot interferometers have recently begun to routinely deliver such observations. We will review some of the most exciting results obtained and the deeper insights they have provided into the characteristics of the solar chromosphere.
