[IGSMAIL-6523] EGU 2012 session: G5.5 Monitoring and modelling of the ionosphere from space-geodetic techniques

[Michael Schmidt]

Dear colleagues,

although we know it is rather late, but we would like to draw your 
attention to our session

G5.5 Monitoring and modelling of the ionosphere from space-geodetic 
techniques

at the European Geosciences Union (EGU) General Assembly 2012 (22-27 
April 2012, Vienna, Austria) and call for contributions.
The relation between space geodetic measurements and ionosphere models 
is twofold: (1) the geodetic measurements can be evaluated to derive 
parameters of physical, empirical or analytical ionosphere models and 
(2) models are used to correct the electromagnetic signals for the 
ionospheric effects. The potential for ionospheric sensing from space 
geodetic techniques has improved considerably over the last few years as 
a result of technological advances, larger ground networks and 
developments of appropriate models and algorithms. Accurate ionospheric 
estimates and retrievals based on these techniques may significantly 
improve our understanding on the physical and dynamic characteristics of 
electron density and space weather at various scales.

We invite contributions on physical modeling of the ionosphere. Recent 
sounding results, report on achieved improvements of the accuracy and of 
the spatio-temporal resolution of derived ionospheric parameters as well 
as theoretical studies that assess requirements for the accuracy of 
relevant parameters are also welcome.
More information on this session as well as on details concerning 
abstract submission and possibilities for financial support of young 
scientists can be found on the following web site:
http://meetingorganizer.copernicus.org/EGU2012/session/9717

The abstract submission deadline is tomorrow, January 17, 2012!

And, of course, we would appreciate, if you could circulate this email 
to colleagues who might be interested.

Many thanks,
Michael Schmidt, Andrzej Krankowski, Mahmut Onur Karslioglu, Denise 
Dettmering

Session abstract:

The relation between space geodetic measurements and ionosphere models 
is twofold: (1) the geodetic measurements can be evaluated to derive 
parameters of physical, empirical or analytical ionosphere models and 
(2) models are used to correct the electromagnetic signals for the 
ionospheric effects. In other words ionospheric signals such as electron 
densitiy or vertical total electron content are either the target 
functions or interpreted as disturbing signals.

Space geodetic techniques such as GNSS (ground- and satellite-based),
DORIS, VLBI, satellite altimetry or the GPS radio occultation missions 
(e.g Formosat-3/COSMIC, TerraSAR-X, OCEANSAT2) can provide valuable 
information on the electron density. The potential for ionospheric 
sensing using these techniques has improved considerably over the last 
few years as a result of technological advances, larger ground networks 
and developments of appropriate models and algorithms. Accurate 
ionospheric estimates and retrievals based on these techniques may 
significantly improve our understanding on the physical and dynamic 
characteristics of electron density and space weather at various scales. 
Consequently, contributions on physical modeling of the ionosphere are 
highly appreciated. Recent sounding results, report on achieved 
improvements of the accuracy and of the spatio-temporal resolution of 
derived ionospheric parameters as well as theoretical studies that 
assess requirements for the accuracy of relevant parameters are also 
welcome.
