| Summary: | The ECOMA (Existence of Charge state Of meteoric smoke particles in the
Middle Atmosphere) sounding rocket campaign was conducted during the Geminid
meteor shower in December 2010 in order to explore whether there is a change
of the properties of meteoric smoke particles due to the stream. In parallel
to the rocket flights, three radars monitored the Geminid activity located at
the launch site in Northern Norway and in Northern Germany to gain
information about the meteor flux into the atmosphere. The results presented
here are based on specular meteor radar observations measuring the radiant
position, the velocity and the meteor flux into the atmosphere during the
Geminids. Further, the MAARSY (Middle Atmosphere
Alomar Radar System) radar was operated to conduct meteor head echo
experiments. The interferometric capabilities of MAARSY permit measuring the
meteor trajectories within the radar beam and to determine the source radiant
and geocentric meteor velocity, as well as to compute the meteor orbit. |
