AB: Four rockets carrying charged dust detectors were launched from Poker Flat in March 2002. The goal of the experiment was to examine the relationship between dust and neutral metals in the Earth's mesosphere. Each of the four identical payloads carried instruments to measure electric fields, charged dust density and plasma density. Ground-based iron and sodium lidars were used to determine conditions near the time of launch. One rocket was launched near midnight on the night of March 6; the remaining three rockets were launched over the course of the night on March 16. The multiple launches have allowed analysis of large-scale motions of charged dust and plasma relative to the lidar-measured neutral metals. In this paper we discuss correlations between measured charged dust densities, plasma densities and neutral metals on the two nights.
