Abstract : This project consists of the design and fabrication of a satellite-borne ultraviolet atmospheric experiment. The components of the instrument will both image and make quantitative polarization measurements of the scattered light from polar mesospheric clouds (PMC) occuring in the high-latitude summertime mesosphere at heights of 85 km. Its scientific objectives are: 1) to determine the morphology, scattering and attenuation properties, occurrence frequency statistics, and statistical distribution of spatial scales of PMC and other aerosol layers in the upper mesosphere; 2) to derive information on the atmospheric wave activity in the summertime mesosphere over all horizontal spatial scales greater than about 2 kilometers; and 3) to determine the mean particle size of PMC particles, to characterize its dependence on latitude, longitude, wave activity and PMC brightness.
