Two autonomous ozone measurement systems for use on ocean buoys and towers have been built and are discussed herein. They are based on low-power atmospheric ozone sensors from Physical Sciences Inc. (PSI) and 2B Technologies. The PSI sensor operates

Shock tubes offer a unique method for studying high temperature properties and/or combustion of particulate. The particles are simply introduced into the shock tube prior to firing and are subsequently heated by gases behind the shock waves. For dilu

Ozone, chlorine monoxide, methane, and submicron particulate concentrations were measured in the stratospheric plume wake of a Delta II rocket powered by a combination of solid (NH4ClO4/Al) and liquid (LOX/kerosene) propulsion systems. We apply a sim

The freezing properties of sulfuric acid droplets were studied by suspending single 20- to 30-μm-diameter particles in a quadrupole trap and cooling them to stratospheric temperatures (≥191.5 K). Each particle's dc balance voltage was measured to
