Abstract [en]

The mesosphere stretches from an altitude of about 50 to 90 km above the Earth’s surface. Meteors entering the Earth’s atmosphere are believed to ablate and hence give rise to a thin layer of dust particles in the upper part of the Earth’s mesosphere. It seems that the dust is most dense in a layer that lies between 80 and 90 km. The dust particles are thought to have sizes of a few to tens of nanometers. Efforts have been made to measure these particles using rockets and radar techniques with limited success. We propose to release dust into the mesosphere over northern Sweden at a height of about 90 km and observe the released dust using the EISCAT radar system. The dust will be launched from the Swedish Space Corporation Esrange Space Centre on a single-stage Improved Orion rocket that will be launched so that its flight path will be in the radar field of view.
