Abstract
Aerosol and cloud chambers are oftentimes used to better understand and constrain processes spanning the multi-scale nature of aerosol--cloud interactions. Because not all processes are resolved and understood, inversion methods are used to determine the parameters controlling experimenting and yield specific results in different configurations. Control theory offers a distinct approach to this inversion problem, as it can formulated to serve both as passive and active control setups. In this presentation, we explore different techniques to help accelerate parameter estimation in chamber experiments. We focus on theoretical underpinnings needed to isolate process regimes most appropriate for experimentation.
