Deep Convective Clouds and Chemistry (DC3)
Data and Information

The Deep Convective Clouds and Chemistry (DC3) field campaign is investigating the impact of deep, mid latitude continental convective clouds, including their dynamical, physical, and lightning processes, on upper tropospheric (UT) composition and chemistry. The primary science objectives are:


  1. To quantify and characterize the convection and convective transport during active convection, investigating a) storm dynamics and physics, b) lightning and its production of nitrogen oxides, c) cloud hydrometeor effects on wet scavenging of species, and d) chemistry in the anvil.
  2. To quantify the changes in chemistry and composition after active convection, focusing on a) 12-48 hours after convection and b) the seasonal transition of the chemical composition of the upper troposphere.


The DC3 aircraft operation was based at the Salina, Kansas from 15 May to 30 June 2012. The DC3 in-situ and remote sensing airborne instruments have generated a great wealth of trace gas and aerosol property observational data sets.  This DOI is for the data set generated from the instruments aboard NASA DC-8 aircraft.
