Abstract

Laboratory and field measurements demonstrate that combustion aerosol from solid rocket motor propellants contain ice nuclei. The measurements indicate an activity at -20°C of about 10^10 nuclei per gram of propellant. When this activity is applied to the 10^9 grams of propellant burned each space shuttle launch and the planned frequent launches are considered, shuttle launch clouds should be an important source of ice nuclei.
