IES2008 TOPICS ACCEPTABLE 

 

Short Synopsis of Topics and Potential Special Sessions

 

1.Space-Weather and ionospheric effects on telecommunication systems 

 

This particular topic will stress the direct relationships between
impairments upon telecommunication systems and space weather events or
phenomena. Telecommunication systems of interest include but are not limited
to the following: longwave communication and navigation systems; shortwave
(HF) communication and OTHR systems; HFDF systems; VHF communication
systems; UHF radar surveillance systems; UHF-SHF satellite communication
systems; L-Band satellite navigation systems (GPS, GLONASS, etc.); cellular
systems. Propagation phenomena and system impairments such as scintillation,
phase fluctuations, loss of phase-lock, angle-of-arrival errors, absorption
effects, ranging errors; radio blackout conditions, optimum working
frequency fluctuations. Actual data is emphasized when possible. 

 

2.Current solar cycle phenomena and impact on operational systems 

 

This topic should stress phenomena observed during the later stages of the
most recent solar cycle (#23) and the emergent solar cycle (#24).
Operational systems are to be emphasized. They could include, but are not
limited to the following: the GPS system and aviation applications such as
WAAS; HF-ALE systems; GLOBALink/HF; Trans-polar HF voice service for
airlines; Milsatcom; etc. 

 

3.Modeling, forecasting, and prediction systems 

 

This topic is dedicated to the elucidation of the myriad of modeling efforts
leading to the development of forecasting and prediction systems. These
efforts and the systems themselves may be directed to the
prediction./forecasting of space weather events (as an end-product) or the
prediction/forecasting of system impairments (where space-weather is an
intermediate product). It is presumed that the space weather events are
pertinent vis-a-vis system effects. Military systems such as SCINDA and
C/NOFS are of interest, and there are many examples climatological
predictions systems that may be subject to update. 

 

4.Ionospheric sounder methods and measurements 

 

This topic encompasses all types of sounder systems and related measurement
techniques, including legacy systems, advanced digital sounders, single
frequency beacons, and wideband probes, deployed either terrestrially and
aboard satellites. Of special interest are sounder techniques that can be
exploited to derive operationally relevant ionospheric information. Another
interest is the comparison of information derived from sounder systems and
independent measurement schemes such as:  in-situ probes (rockets and
satellites), incoherent scatter techniques, etc. 

 

5.Multi-Sensor contributions to the solution of Space-Weather effects on
ionospherically-dependent systems 

 

This topic involve an examination of the ionosphere using multiple sensors,
such as the sensors suggested under the international DASI effort. These
sensors may include radio receivers and telescopes, ionosondes, radars, TEC
polarimeters, magnetometers, optimal instruments, solar imagers, and so on.
The multi-sensor approach enables corroborative measurements to be obtained,
and allows for a more general evaluation of the ionospheric personality
during periods of system disturbance, or inferred impairment events. 

 

6.Applications of ionospheric tomography 

 

Ionospheric tomography is a relatively new imaging technique that allows for
evaluation of Ne gradients and large-scale structures. These are important
during disturbed geomagnetic periods. Of special interest are studies that
have been stimulated by the International Polar Year (IPY:2007-2008).

 

7.Transionospheric effects, including scintillation 

 

This topic emphasizes the impact of the ionosphere on radiowaves transmitted
to/from satellites and even signals from radio stars. Of primary interest
are propagation effects such as Faraday rotation, phase and amplitude
scintillation, wedge refraction, ranging errors, group path delay
fluctuations, and miscellaneous phase path effects. Examples include
scintillation introduced on the GPS space segment, and scintillation
impairments in connection with communication systems, observed especially
during geomagnetic storms, emphasizing polar, auroral, and equatorial
regions. 

 

8.Ionospheric effects on WAAS and other systems supporting aviation 

 

This topic is dedicated principally to ionospheric effects on radio systems
(i.e., navigation and communication) that support aviation. Satellite
communication and shortwave voice/data communication systems are of
interest, especially for flights passing through geophysical regions such as
the polar cap and the equator, that sometimes exhibit pathological behavior.


 

9.High Frequency communication and surveillance systems 

 

This topic is principally dedicated to the ionospheric and space-weather
effects on high frequency (HF) communication and surveillance systems (i.e.,
HFDF, HF-SSL, and OTHR). The communication systems include legacy voice and
data link (i.e., HFDL). 

 

10.Longwave propagation systems and effects 

 

This topic concerns the interaction of certain legacy systems used for
navigation and communication at frequencies belonw the shortwave (i.e., HF)
band. Many of these systems are still is use and are of importance in backup
scenarios. Other applications may be primary in nature

 

11.Global Positioning System and total electron content studies 

 

This topic emphasizes the impact on the ionospheric electron content (i.e.,
TEC) upon navigation systems that operate using methodologies for which the
compensation is non-existent or incomplete. Examples include
single-frequency GPS receivers.

 

12.Impact of the lower atmosphere on the Ionosphere 

 

It is well known that the lower atmosphere is a source of atmospheric
gravity waves, infrasonic waves and other oscillations that may introduce
ionospheric tracers to the underlying neutral gas motion. Ionospheric
factors include traveling ionospheric disturbances (TID) and other
variations in the electron density distribution. Lower atmospheric chemistry
and dynamics are also relevant subjects to consider under this general
topic. An interesting aspect is the impact of space weather and the
ionospheric personality upon the lower atmosphere. 

 

13.Contribution of the IHY to the understanding of the ionosphere at all
longitudes 

 

This topic will look to contributions by participants in studies associated
with the International Heliospheric Year. Collaborative investigations and
reports are of primary interest.

 

14.Impact of global electrodynamics on the storm-time ionosphere 

 

Knowledge of the storm-time ionosphere is of paramount interest to system
engineers as well as practicing ionosphericists. There have been a number of
theoretical models that may account for many aspects of the storm-time
ionospheric morphology, and many aspects of the behavior are now understood.
Still other aspects of the geomagnetic storm are not known, and there are
inconsistencies from one storm to the next. Empirical models have provided a
useful procedure for estimating the general behavior of ionospheric storms.
Global electrodynamics can provide a macroview of the important phenomena,
and along with empirical data for verification, may be the way forward and
lead to a more fulsome understanding. Studies of storm behavior through the
lens of global electrodynamics are solicited.  

 

15.Results derived from COST-ACTION programs (viz., 238, 251, 271, 724, and
296). 

 

This topic pertains to COST Actions undertaken by the European community and
its affiliates having relevance to the ionosphere and space weather effects
upon telecommunication systems. These Actions, including 238, 251, 271, 724,
and 296, are to be emphasized. A limited number of papers would be devoted
to programmatic aspects, but more substantive scientific and engineering
studies are requested. 

 

16.Impact of solar noise bursts and environmental noise on telecommunication
and navigation systems 

 

This topic recognizes that system performance typically depends upon
signal-to-noise (SNR) ratios, and that systematic, man-made, and
environmental noise are major factors in the determination of how well a
radiowave system may perform. Studies of man-made noise, galactic noise,
atmospheric noise, and cosmic noise bursts are welcome. Solar noise bursts
have been shown to have a significant impact upon the GPS system., and
recent studies (circa 2006 and following) have demonstrated measurable
impacts upon navigation systems dependent upon the GPS waveform. Further
examination of these effects would be of interest. 

 

17.Space-Weather program activities having relevance to ionospheric effects
on C3I and navigation systems 

 

18.Products and services offered by industry relevant to prediction &
forecasting of ionospheric effects 

 

19.Government projects associated with the forecasting and/or mitigation of
deleterious effects on national and/or military systems 

 

20.Studies of documented system impacts during major geomagnetic storms and
other solar-generated events
