Impact of meteor showers on mesospheric smoke particles - Geminides campaign

Location:

This proposal concerns expenses for launching and data analysis of a campaign to be carried out in 2010, in cooperation with Institute of Atmospheric Physics (IAP) in Kühlungsborn, Germany. This application is for the Norwegian part (approx 50%) of the co sts. We will launch rockets from Andøya into the polar mesosphere, to study properties of mesospheric aerosol particles. The rockets carry instruments to measure the density of charged and neutral aerosol particles, collect samples to be analysed in the laboratory, as well as plasma instruments. In addition, ground-based lidar and radar instruments will be used to measure temperature and electron density. The data analysis will also make use of a numerical model for the interaction between aerosol par ticles and the ambient electrons and ions. The campaign comprises three rocket launches, and will measure the smoke particle density before, during, and a few days after the Geminides meteor shower in December, to determine whether meteor showers lead to a significant change in smoke particle density.
