The Deep Convective Clouds and Chemistry (DC3) field campaign is investigating the impact of deep, midlatitude continental convective clouds, including their dynamical, physical, and lightning processes, on upper tropospheric (UT) composition and chemistry. The campaign is making use of extensively instrumented aircraft platforms and ground-based observations.
Salina, Kansas is the base location for the three research aircraft and the project operations center at the Salina Airport, while a network of ground-based radar, lightning antenna stations and instrumentation in Colorado, Oklahoma and Alabama is used to support DC3 during the project from 15 May - 30 June 2012.

DC3 is motivated by determining the role of thunderstorms on the concentration of ozone in the upper troposphere, where ozone acts as a greenhouse gas.
