Dear all,
EISCAT_3D construction is progressing well. The EISCAT Scientific
Association is currently installing the EISCAT_3D antennas at the
transmitter site in Skibotn, Norway and at the receiver sites in
Kaiseniemi, Sweden and in Karesuvanto, Finland. The current schedule is
to start EISCAT_3D operations in 2023, first in the monostatic mode. In
parallel, EISCAT is planning to develop the legal status of the
organisation in order to achieve long-term stability. The goal remains
non-military scientific operations of the radar to study the Arctic
upper atmosphere and ionosphere as well as geospace phenomena. Efforts
will be made to reduce any negative impact of these changes on the
EISCAT user community, allowing uninterrupted use of the
facilities. Follow the updates of EISCAT_3D on

EISCAT Council
The call for papers of the URSI 2023 General Assembly and Scientific
Symposium (Sapporo, 19-26 August, 2023) is now open.
We encourage the community to submit achievements, results, and thoughts
on next generation incoherent scatter facilities and networks to the session
G08: New results and contemporary developments in incoherent scatter radar
This session will focus on advances in technique and scientific results
within the field of incoherent scatter radar (ISR) observations of the
geospace environment. The ISR technique represents the most powerful
ground-based probe of the ionospheric plasma, and allows extensive and
precise studies of processes and features in the ionosphere, atmosphere,
plasmasphere, and magnetosphere. The session provides a platform
concentrating on results from coordinated, multi-radar experiments along
with opportunities for discussion of upcoming plans using existing and
future facilities. Topics of interest include long-period continuous
runs for long term trend studies, World Day program operations and
suggested changes, sensor fusion analysis with ISR data as a central
feature, harmonization of ISR data outputs, and advanced derived
scientific products. Contributions are also welcome regarding planning
of next generation observations using future advanced ISR facilities and
networks.

Dear colleagues,
As the AGU Fall Meeting is around the corner, this means that it is also
EGU abstract submission season! The EGU General Assembly will take place
as a hybrid conference (in Vienna, Austria and online) on 23–28 April 2023.
We would like to draw your attention to Session ST3.6: Ionosphere –
upper atmosphere physics with ground-based instrumentation
<https://meetingorganizer.copernicus.org/EGU23/session/46384>. The
session description can be found at the bottom of this e-mail.
Please note that the abstract submission deadline for EGU23 is on
*Tuesday, 10 January 2023 at 13:00 CEST*. Guidelines on the abstract
submission process can be found on this page
<https://egu23.eu/programme/how_to_submit.html>.
Please do not hesitate to forward this announcement to your colleagues
who make use of ground-based instrument data in their studies of upper
atmospheric and ionospheric processes.
We are looking forward to your contributions and to seeing you at EGU23!
Best regards,
The EGU ST3.6 session convening team:
Veronika Haberle, Maxime Grandin, Jia Jia, and Frederic Pitout

Abstract submission
<https://meetingorganizer.copernicus.org/EGU23/abstractsubmission/46384>
The Earth’s upper atmosphere and ionosphere are subject to significant
variability associated with solar forcing. While in situ observations of
the ionosphere-upper atmosphere are only possible with spacecraft and
sounding rockets, a wealth of information is obtained thanks to remote
sensing techniques using ground-based instruments.
For instance, ground-based magnetometers, used in dense networks,
routinely enable the derivation of ionospheric currents and geomagnetic
indices. Optical instruments not only provide measurements of auroral
and airglow emissions, but are also used to observe upper atmospheric
winds and temperatures, e.g. in the thermosphere and mesosphere. Such
parameters can also be measured with radars, spanning a wide range of
active (ionosondes, meteor radars, coherent and incoherent scatter
radars, VLF transmitters, Lidars) and passive (riometers, VLF receivers)
systems.
Combining ground-based observations from various instruments enables the
development of novel data analysis methodologies which in turn enhance
our understanding of the underlying physics of space weather and
ionosphere-upper atmosphere processes. This includes the study of
densities, temperatures and composition of the ionosphere–upper
atmosphere, monitoring of its dynamics and chemistry, and measuring of
fluxes from precipitating particles and current systems.
In this session, we invite contributions featuring the use of
ground-based instruments in studies of the ionosphere–upper atmosphere
system across all latitudes and of space weather and
ionospheric–atmospheric physics processes of various time and spatial
scales.
