July 27, 2011, Subject: AGU Fall Meeting abstract deadline: August 4
Dear ASE members,
I just wanted to remind everyone of the early AGU Fall Meeting abstract deadline
this year. It is **4 August**, with a 23:59 EDT cut-off for those of you really
planning on waiting until the last minute.
There are planned special sessions on Energetic Radiation from Thunderstorms and
on Thunderstorm Effects in the Near-Earth Space Environment. And as always
general contributions on lightning and thunderstorm electricity are welcomed and
will be organized into other ASE sessions.
Thanks and best regards,
Steve Cummer
Chair, ASE Focus Group
May 5, 2011, Subject: AGU ASE Focus Group Announcement: Abstract Deadline Extended
Dear ASE Focus Group Members,
After the tornadoes in Alabama last week, and several days with no power and some chaos, we are gradually getting back to normal, including resuming our planning for the TGF workshop to be held in Huntsville, 13-14 July 2011. The abstract submission deadline has passed, but we don't know if or for how long our website was knocked offline during the recent power and communication outages. In any case, we would like to extend the abstract submission deadline for one week and will welcome until 11:59 PM CDT on 11 May 2011 abstracts related to the workshop topics.
Details are available on the Center for Space Plasma and Aeronomic Research (CSPAR) Web site.
We look forward to seeing you in Huntsville.

Mar. 9, 2011, Subject: Call for ASE Focus Group related abstract submissions to ESPC-DPS Joint Meeting
The joint meeting of the European Planetary Science Congress and the Division of Planetary Sciences of the American Astronomical Society
[ESPC-DPS] will be held in Nantes, France, from 3-7 October, 2011.
Please consider submitting to the session "Electrical phenomena on other planets: lightning discharges, corona and sprites" convened by Yoav
Yair, together with Yukihiro Takahashi, Karen Aplin, Georg Fischer and Fernando
Simoes.
http://meetingorganizer.copernicus.org/EPSC-DPS2011/session/8888
This session seeks contributions on lightning generation mechanisms, charging and occurrence of flashes on other planets, as well as laboratory work on the spectrum and energy of such discharges. We welcome submissions on surface electrical processes such as charging of dust and aerosols, especially with exobiological importance. Works related to detection of planetary lightning from orbit and from earth's surface, as well as from future space missions are highly encouraged.
The deadline for abstract submission is 31 May 2011.
Regards,
Yoav Yair

Mar. 1, 2011, Subject: Updated ASE Web Page and Outstanding Student Presentation Awards 2010
Dear AGU ASE Focus Group Members,
First, I would like to offer my congratulations to the 3 winners of Outstanding Student Presentation Awards from the ASE Focus Group from the 2010 AGU Fall Meeting. They are:
Sonja Behnke, New Mexico Tech, Advisor: Ron Thomas, "The life cycle of Redoubt's Volcanic Lightning Storms"
Jianqui Qin, Penn State, Advisor: Victor Pasko, "On the inception of streams from sprite halo events produced by lightning discharges with positive and negative polarity"
Can Liang, Stanford University, Advisor: Umran Inan, "Toward a Time- Domain Fractal Lightning Simulation"
There was one presentation selected for an honorable mention:
Manabu Akita, Osaka University, Advisor: Zen Kawasaki, "Relationships between Lightning Leader Progression Characteristics and Local Charge Structures in Thunderclouds"
Again, my congratulations to the student awardees and their advisors. Thanks as well to Richard Sonnenfeld and Jeremy Thomas for coordinating and leading the judging. It is a non-trivial but very important task, and the ASE community thanks you both.
Second, the ASE Focus Group Web page has recently been updated for the first time in quite a while. The new page reflects the new OSP awardees and also contains an archive of ASE community emails. We expect to have an additional and more substantive Web page update before too long with a more modern and useful format. Please stay tuned for that.
Best regards,
Steve Cummer

Message to ASE Focus Group from Valerie Connaughton (Valerie@nasa.gov)
*****************
After determining there was sufficient interest to hold a summer meeting in the
US on diverse topics related to Terrestrial Gamma-ray Flashes (TGFs), we have
chosen the following dates to accommodate the most popular choice in our doodle
poll:
13-14 July 2011
The workshop will be on the campus of the University of Alabama in Huntsville.
Over the next few weeks we will set up a registration web page and issue a call
for submissions. These will be linked from
http://gammaray.nsstc.nasa.gov/gbm/science/tgf
Thanks to all of you who responded to our poll, and we look forward to seeing
you this summer in Huntsville, Alabama.
Please contact Valerie Connaughton (valerie@nasa.gov)
and Michael Briggs (michael.briggs@nasa.gov)
if you have any questions.
Jan. 19, 2011, subject line: Upcoming TGF Workshop
Dear ASE Focus Group Members:
Planning is underway for a 2 day workshop on terrestrial gamma ray flashes to be
organized by the University of Alabama at Huntsville. Preliminary
information can be obtained at http://gammaray.nsstc.nasa.gov/gbm/science/tgf/.
The workshop will take place in the summer of 2011 but the dates are not yet
finalized. The website above contains a link to a Doodle poll with which
interested parties can express a scheduling preference. Please participate
if you are interested.
Additional information can be obtained from Michael Briggs (Michael.S.Briggs@nasa.gov)

December 30, 2010, subject: EGU General Assembly Lightning Session
Dear colleagues,
This is a reminder that we are fast approaching the January 10th, 2011 deadline!
The EGU GA will be held in Vienna, April 3-8th 2011. We would welcome
submissions to the session described below.
The session number is: NH1.4/AS4.4: - please use the COSIS system.

Lightning: physics, detection and atmospheric effects
Convener: Yoav Yair
Co-Conveners: Serge Soula , Colin Price , Hans D. Betz , Yukihiro Takahashi
Lightning is the energetic manifestation of electrical breakdown, occurring
after charge separation processes operating on micro and macro-scales, leading
to strong electric fields within thunderstorms. Lightning is associated with
severe weather, torrential rains and flash floods. It has significant effects on
various atmospheric layers and drives the fair-weather electric field. This
session seeks contributions from research in atmospheric electricity regarding
cloud physics and lightning, meteorology of thunderstorms, lightning discharge
physics, modeling of the electricity of thunderstorms, lightning and the global
circuit, atmospheric chemical effects of lightning and lightning in relation
with middle atmospheric transient luminous events. The session also welcomes
contributions on lightning detection networks and sensors from ground and space,
presenting results of global and local surveys, also considering future
lightning patterns in an era of climate change and urban effects on lightning.
The real-time capabilities of present-day lightning detection systems provide a
potential for using lightning data for now-casting and verification of weather
forecasts. The session welcomes new ideas and practical methods for utilizing
lightning data.
We look forward to seeing you in Vienna!
On behalf of the co-conveners,
Warm regards from Yoav
