[IGSMAIL-7696] Call for abstracts for EGU 2019 session G2.5: Combination strategies for consistent geodetic products

[Bloßfeld, Mathis]

Dear colleagues,

we, that are Mathis, Sara, Alexandre and Benedikt, want to invite you to 
submit an abstract to our new session on "*Combination strategies for 
consistent geodetic products*" (G2.5) at the EGU General Assembly 2019 
in Vienna, Austria (7.-12. April 2019). The deadline for the abstract 
submission is *10. January 2019*!!

This session will be a totally new session covering all topics around 
the combination of geodetic techniques and parameters. Geodetic 
parameters, as we all know, are integral quantities of a complex and 
continuously changing planet Earth and therefore, we have to study and 
understand their interactions and resulting potential tradeoffs in their 
common adjustment. Please find below the detailed session description:

The combination of space and terrestrial geodetic techniques is a 
prerequisite for the integrated estimation of a multitude of geodetic 
parameters such as quasar and station positions (and the respective 
motions), satellite orbits, Earth's gravity field coefficients, Earth 
orientation parameters (EOP), Earth's thermospheric parameters and 
atmospheric conditions. These parameters depend strongly on combination 
strategies or adjustment theories like the least-squares and Kalman 
filter estimation at different levels and the co-location on ground and 
in space. The estimated parameters are affected by real geophysical 
signals and artifacts in geodetic observations at the same time. Their 
separation still yields a very challenging objective. Moreover, the 
consideration and interpretation of inter-technique and inter-parameter 
correlations and dependencies may enhance our knowledge on systematic 
effects, improve the consistency between different observational 
techniques, and may help to mitigate artifacts in geodetic time series. 
In addition to the prior mentioned aspects, also the time transfer 
between observing systems and integrative technologies at fundamental 
stations help revealing inter-technique biases. All these estimation and 
combination strategies provide invaluable tools to identify and to 
potentially resolve technique-specific or inter-technique biases.
This session provides a forum to discuss combination strategies, future 
integrative technologies, parameter correlations, and inter-technique 
biases w.r.t. their impact on geodetic parameters. We especially 
encourage contributions that focus on the combined adjustment of 
parameters to improve their consistency and contributions that address 
innovative combination strategies.

This session is organized and chaired by*E**arly Career Scientists*! Our 
session also participates in *peer-reviewed proceedings* available for 
the first time at the coming EGU 2019. If you submit an abstract to our 
session, you will have the opportunity to publish your research in an 
*open-access EGU journal*.

We apologize if you get this email multiple times via different mailing 
lists!

If you have any further questions please contact any of us directly;-)

See you in Vienna,
