Dynamics and Chemistry of Marine Stratocumulus—DYCOMS-II

T he experiment consisted of two basic flight patterns: entrainment and radar flight patterns.The entrainment flight patterns had a twofold objective: to measure divergence and turbulent fluxes at various levels and characterize the mean states of both the boundary layer and the overlying air column.To achieve these objectives, the basic entrainment flight plan consisted of stacks of 30-min (approxi-mately 60-km diameter) circles.In contrast the objective of the radar flights was to characterize the evolution of a specific convective cell.For this reason, the radar flights consisted of shorter (6 min) legs that attempted to fly over or through a specific point in the flow along varied headings.These differences between the two types of flight patterns are shown in Fig. S1.
