Dear Colleagues,

This is Dong-Kyu KIM who operate SUWN site in south korea.

>From Dec 21 (GPS 355day) 2006 to Jan 2 2007, There were antenna height error at SUWN rinex file.
I thought that changing some script resulted in rinex conversion error.

Be careful to process this period data, Absolutely You have to reprocess this period data.

I uploaded this data again at IGS data center.

Correct antenna height is 1.57 m, model is trimble choke ring antenna (TRM29659.00).
No change at present site info file at igs web site.

Subject: [IGSMAIL-5525]: Combined IGS clocks with 30 second sampling

IGS Electronic Mail 05 Jan 03:44:13 PST 2007 Message Number 5525

Author: Gerd Gendt

Dear colleagues,

Four of the IGS Analysis Centers are now generating regularly satellite clocks
with a sampling rate of 30 seconds. This allows us to start with a combination
of those clocks.

Starting with the Final products for GPS week 1406 we will provide in parallel
to the normal 5-minute clock file (*.clk) a second file named *.clk_30s, which
contains the higher sampled satellite clocks.
The 5-minute clocks are identical in both files.

Any feedback will be appreciated.

Best regards
Gerd Gendt

Dear Colleagues -

As part of the 2007 General Assembly of the European Geosciences
Union that will be held in Vienna, Austria during 15-20 April 2007,
Hans-Peter Plag and I are convening session G4/GD17 on "What
constraints do earth rotation, shape, and gravity measurements place
on the dynamical processes of the solid earth?". The description of
the session is given below.

We would like to draw your attention to this session and encourage
you to participate in it. The deadline for submitting abstracts is 15
January 2007.

Hope to see you in Vienna!

Best regards,
Richard Gross and Hans-Peter Plag


G4/GD17: What constraints do earth rotation, shape, and gravity
measurements place on the dynamical processes of the solid earth?

Measurements of the Earth's rotation, shape, and gravity provided by
the Global Geodetic Observing System show that they change on a wide
range of time scales reflecting the wide range of processes affecting
them, from external tidal forces to surficial processes involving the
atmosphere, oceans, and hydrosphere to internal processes acting both
at the core-mantle boundary as well as within the solid Earth itself.
In addition, the frequencies of the resonances in the Earth's
rotation, including the Chandler wobble, the free core nutation, the
free inner core nutation, and the inner core wobble, depend upon the
internal structure and constitution of the Earth. Measurements of the
Earth's rotation, shape, and gravity can therefore be used to place
constraints on a wide range of dynamical processes of the solid
Earth, including glacial isostatic adjustment, mantle anelasticity,
core-mantle coupling, core flattening, core angular momentum,
torsional oscillations of the core, the tilt and rotation of the
inner core, and the strength of the magnetic field at the inner core
and core-mantle boundaries. This session will be a forum for
discussing the use of Earth rotation, shape, and gravity measurements
to constrain the structure and dynamical processes of the solid Earth.
