<div dir="ltr"><p>Dear colleagues,</p><p>You are cordially invited to participate in a special session on high-latitude electrodynamics, which is scheduled at 1:30-3:30PM on Monday, June19. The session is also a tribute to Art Richmond’s distinguished career and
his contributions to the scientific field. If you would like to contribute a short presentation, please let one of the co-conveners know as soon as possible but no later than June 14th.<br></p><p><b>Session Description:</b><br></p><p>Distributions of
high-latitude ionospheric electrodynamic fields such as plasma
convection and auroral precipitation have traditionally been represented
by empirical models constructed by combining observations taken over a
long period of time through sorting and binning according to different
geophysical parameters. Though empirical models provide robust
representations of the average ionospheric behavior, they are often
inadequate to replicate the electrodynamic features pertained to
specific geophysical conditions especially during storms. High-latitude
ionospheric convection and auroral precipitation are two most important
forms of energy input into the thermosphere, which are responsible for
producing various thermospheric disturbances during geomagnetic storms.
With the expansion of ground-based (e.g., SuperDARN, IS radars, ground
magnetometer chains, auroral imagers, and GPS receivers) and satellite
(e.g., DMSP, AMPERE, TIMED, COSMIC) observations, along with the
advancement in numerical modeling and data assimilation techniques,
significant progresses have been made in the understanding of
high-latitude ionospheric electrodynamics in recent years. This session
focuses new numerical techniques and data assimilation methods to reveal
new features of the high-latitude ionosphere.
The session solicits papers on modeling and observational studies as
well as data assimilation analysis of high-latitude ionospheric
electrodynamics.</p><p>More information on the session can be found at <a href="http://cedarweb.vsp.ucar.edu/wiki/index.php/2017_Workshop:High_Latitude_Electrodynamics">http://cedarweb.vsp.ucar.edu/wiki/index.php/2017_Workshop:High_Latitude_Electrodynamics</a></p><p>Regards,</p><p>Gang Lu, Yue Deng, Tomoko Matsuo, Delores Knipp<br></p><div><div class="gmail_signature"><div dir="ltr"><div><div><div><div>-------------------------------------------------------------------<br>Gang Lu<br></div>High Altitude Observatory<br></div>National Center for Atmospheric Research<br></div>3080 Center Green Drive, Boulder, CO 80301<br></div><div>email: <a href="mailto:ganglu@ucar.edu" target="_blank">ganglu@ucar.edu</a><br></div><div>Phone: 303-497-1554 (office); 303-495-9990 (cell)<br></div><div>Fax: 303-497-1589<br>------------------------------------------------------------------<br></div></div></div></div>
