Full Name: Aviation Climate Change Research Initiative (ACCRI)

Platform/Location/Time: NASA Glenn High Altitude Research Chamber

Overall Goal: Understanding at a process-level how soot coatings affect ice crystal formation under simulated contrail conditions

What we studied:
Ice crystal formation on propane-burner-generated soot. Soot was either uncoated or coated with organics and sulfuric acid.

LARGE Publications:
Wong et al., “Laboratory and modeling studies on the effects of water and soot emissions and ambient conditions on the properties of contrail ice particles in the jet regime”, ACP, 2013.
