This year at the 2010 CEDAR Workshop at the University of Colorado in Boulder, we have two memorial talks to honor a couple of giants in our field who passed away within the last year. Michael Mendillo of Boston University will give the Memorial talk on Henry Rishbeth at 10 AM on Wednesday 23 June, while Richard Behnke of the National Science Foundation will honor Bill Gordon at 10 AM on Thursday 24 June. These memorial talks are free to the larger local scientific community in the Boulder area or visitors who might wish to honor these colleagues. The memorial talks will be held at Math-100 and are just after the morning breaks which start at 0930 AM so that any visitors can mingle with the conference participants right before the memorial talks. Further details are on the agenda at http://cedarweb.hao.ucar.edu/wiki/index.php/2010_Workshop:Agenda.
(2) Invitation to submit talks for CEDAR 2010 Workshop: Meteoroids and Meteors: Impact Effects (S. Close, L. Dyrud).
From Sigrid Close (email@example.com).
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.
Please contact Sigrid Close (firstname.lastname@example.org) with at least a title of what you would like to present. The workshop description is located at http://cedarweb.hao.ucar.edu/wiki/index.php/2010_Workshop:Meteoroids_and_Meteors. Please do not change this description or add your name to a list of speakers without contacting the conveners (email@example.com and firstname.lastname@example.org).
