Deep Convective Clouds & Chemistry Project
- northeastern Colorado,
- west Texas to central Oklahoma, and
- northern Alabama in order to gather data on different types of storms and with different boundary layer compositions as well as to ensure sampling of convection during the time period of the field campaign. The types of storms sampled were air mass, multicell, and supercell convection.
The DC3 project addressed the following goals:
- Quantify and characterize the convective transport of fresh emissions and water to the upper troposphere within the first few hours of active convection, investigating storm dynamics and physics, lightning and its production of nitrogen oxides, cloud hydrometeor effects on wet deposition of species, surface emission variability, and chemistry in the anvil.
- Quantify the changes in chemistry and composition in the upper troposphere after active convection, focusing on 12-48 hours after convection and the seasonal transition of the chemical composition of the UT.

Education and Outreach
The DC3 project provided broader impacts to society via extensive education and outreach activities, and via improved understanding of sources of UT ozone, an important constituent to climate and air quality, for assessment reports and resulting policy implications. Further, DC3 measurements are instrumental in improving model parameterizations of convective transport, production of NO by lightning, and wet deposition of chemical species.
