This report presents particulate concentration, emission index and size distribution data in the plume of a TF30-P1 engine, run at military power in the open air. The particle size distribution data measured here show that the mass median aerodynamic diameter of the particles is in the range of 0.19-0.30 micrometer compared to an average of 0.18 micrometer for the test cell data for a rebuilt TF30-P414 engine. Recommendations are listed for future tests.

Artificial fogs grown on hygroscopic (Salty Dog) nuclei were produced in the marine environment over Laser Bay, San Nicolas Island, California. These fogs were studied using over water optical extinction measurements in the visual, near and far infrared bands as well as by aerosol size measurements from an instrumented aircraft and from a shore based instrument. These studies show that optical extinction in the visible and near infra red wavelengths produced by biologically safe hygroscopic nuclei can be generated in military significant scales in the marine boundary layer.
