Description
A meteoroid is defined as a small, solid extraterrestrial object. Upon entry into a planet’s atmosphere, it heats and ablates off particles that then collide with the background neutrals, forming a dense plasma that extends around the meteoroid as well as behind it. These plasmas, referred to as meteors, have been studied for well over a century, yet many outstanding questions remain. These include, but are not limited to, the amount of material deposited into Earth’s atmosphere, the mass flux, the energy flux, and the impact of this flux on upper atmospheric chemistry and ionization. Of particular importance to the CEDAR community is that meteors account for all of the dust, metal neutral and ionized particles in the upper atmosphere. Further, meteoric dust is also thought to provide the condensation nuclei for polar mesospheric clouds PMC (high altitude clouds near 80 km), which is the focus of a current NASA mission (AIM). Additionally, CEDAR researchers have used radar reflections from meteor trails to remotely sense winds and temperatures near the mesopause.
To address these issues, we invite presentations on the physics of meteors and their impact effects on the atmosphere and ionosphere, as well as engineering techniques for observing and characterizing the meteoroid population. We encourage presentations using any data set, including Lidar, radar, and optical, as well as theoretical modeling of meteoroid impact effects.
This year we will continue a panel discussion begun in 2009 on the following topic. " How do we make sense of non-smooth radar “light curves”?” This topic has been the result of a number of recent papers, and disagreement between different researchers. We look forward to a very interesting discussion amongst panel and audience members.
