Dear Colleagues, 
(with apologies to those on multiple lists)

We encourage your abstract submissions (web deadline: 9 September) to the 
following special Geodesy session of the Fall 2004 AGU meeting, to be held in 
San Francisco 13-17 December <http://www.agu.org/meetings/fm04/>.  We would 
like this session to be a forum on reference frame procedures that scientists 
actually use to compute station velocities or time series, and that are proving 
to be effective for scientific interpretation.  The focus is not on producing 
station coordinates within a conventional frame, but rather on station 
kinematics for scientific investigations in practice, and so the concept of 
a "frame" here is intended to be very broad, the focus being on "practice".

Session G09: Reference Frame Procedures in Practice to Enhance Scientific 
Investigations 

We solicit scientific investigators to present papers on the actual practice of 
reference frames to specific scientific problems. Scientific investigators do 
not necessarily apply the same conventional reference frame procedure to all 
scientific problems, but often apply various procedures appropriate to the 
signal under investigation. Reasons for selecting a specific procedure might be 
to improve signal to noise ratio in station coordinate time series, or to 
simplify the scientific interpretation by a physically useful choice of datum, 
or to simplify the analysis in cases where the choice of frame is irrelevant. 
Scientists often do not require accurate determination of station positions, 
but they more generally do require very precise knowledge of station 
kinematics. Reference frame procedures appropriate to the study of seasonal 
loading signals might be more relaxed than studies that also require scientific 
interpretation of secular loading signals. Frames used in practice for the 
study of secular tectonics might not be the same as those for the study of 
secular loading or GIA. Depending on the situation, frames procedures that 
produce globally-reference coordinate time series (such as fiducial-free 
precise point positioning) may be more or less effective for scientific 
interpretation of tectonics than regionally-filtered coordinate time series. We 
welcome papers that present results on the application of reference frame 
procedures to specific scientific problems, and also papers that discuss the 
effectiveness of different possible procedures appropriate to scientific 
problems over a wide variety of spatial and temporal scales. Our definition 
of “reference frame procedure” is intended to be broad, including spatial and 
temporal filtering schemes. 

Thank you for your consideration, 

Geoff Blewitt, Zuheir Altamimi, and Mike Craymer
