IAG Young Author Award 2005

The winner of the IAG Young Author Award 2005 is Mr. Roland Pail for his paper:

A parametric study on the impact of satellite attitude errors on GOCE gravity field recovery (Journal of Geodesy, Vol. 79, No. 4 - 5, pp. 231 - 241, 2005).

Roland Pail was born in Mariazell, Austria, in 1972. He studied geophysics at the University of Vienna, finishing his diploma thesis in 1995.

After working as a research associate at the Institute of Physics at the University of Bayreuth, Germany, in the framework of the DFG project “Continental Deep Drilling Project of the Federal Republic of Germany”, in 1997 he joined the Graz University of Technology as a university associate. He received his Ph.D. degree “sub auspiciis praesidentis “ at Graz University of Technology in 1999. His doctoral thesis was entitled, “Synthetic Global Gravity Model for Planetary Bodies and Applications in Satellite Gravity Gradiometry”.

After his habilitation in “Theoretical Geodesy” in 2002 (habilitation thesis: “Selected problems in the framework of the GOCE data processing”), he became assistant professor at the Institute of Navigation and Satellite Geodesy at the Graz University of Technology.

He received the Appreciation Award of the Federal Ministry of Science, Transport and Art 1996 and 1999, the Josef-Krainer-Promotion Award in 2000, and the Allmer-Löschner-Award of the Austrian Geodetic Commission in 2000.

His scientific interests are mainly in the fields of satellite geodesy, satellite gradiometry, Earth gravity field determination, synthetic Earth models and inverse problems. He has been project manager of diverse national projects and is currently work package manager of the ESA project “GOCE High-Level Processing Facility”. He is also member of several IAG study groups.

Congratulations to Mr. Pail for the award!

IAG Central Bureau

The COSMIC satellites succesfully launched

BOULDER—A globe-spanning constellation of six satellites expected to improve weather forecasts, monitor climate change, and enhance space weather research headed into orbit on April 15. A Minotaur rocket launched the array from Vandenberg Air Force Base.

The low-orbiting satellites will be the first to provide atmospheric data daily in real time over thousands of points on Earth for both research and operational weather forecasting by measuring the bending of radio signals from the U.S. Global Positioning System (GPS) as the signals pass through Earth's atmosphere.

Called COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate) in the United States and FORMOSAT-3 in Taiwan, the $100 million satellite network is the product of an agreement between the American Institute in Taiwan and the Taipei Economic and Cultural Representative Office in the United States. The array is based on a system design provided by the University Corporation for Atmospheric Research (UCAR).

Temperature and water vapor profiles derived from the GPS data will help meteorologists observe, research, and forecast hurricanes, typhoons, and other storm patterns over the oceans and improve many areas of weather prediction. The stability, consistency, and accuracy of the measurements should be a boon to scientists quantifying long-term climate change trends.

COSMIC's measurements of electron density in the ionosphere are expected to improve analysis and forecasting of space weather, including geomagnetic storms that can interrupt sensitive satellite and communications systems and affect power grids on the ground.

COSMIC relies on a technology known as radio occultation. Just as the water molecules in a glass change the path of visible light waves so that a pencil appears bent, molecules in the air bend GPS radio signals as they pass through (are occulted by) the atmosphere. By measuring the amount of this bending, scientists can determine underlying atmospheric conditions, such as air density, temperature, and moisture, and electron density.

"This is the first time the technique of radio occultation has been used on a large scale in real time to provide nearly continuous measurements of worldwide atmospheric conditions at all altitudes," says William Kuo, director of the UCAR COSMIC office.

Mrs. Ruth E. Neilan has been appointed as IAG representative to ICG

IAG has appointed Mrs. Ruth E. Neilan as representative to United Nations International Committee on Global Navigation Satellite Systems (ICG). Mrs. Neilan is a member of the IAG Executive Committee.

IAG Central Bureau

Call for Proposal – Nominations open for IAG Secretary General

The present Secretary General, C.C. Tscherning, has served for 3 periods, and cannot be re-elected. The election of a new Secretary General (SG) will take place in the spring of 2007 together with the election of other officers for the 2007-2011 period.

The commitment associated with this position is heavier than that associated with any of the other IAG executive positions. The IAG executive committee has therefore decided to separate the election of the new Secretary General from the other nominations and elections, because the election is based on a call for proposals, which have to be evaluated by the IAG Executive.

The duties of the SG are described in the by-laws, section 2.5.3, as quoted below. Since the SG will also be the director of the Central Bureau, a nomination automatically implies a commitment to host the Bureau, as well.

According to the by-laws, the SG receives no salary, but the expenses of the SG may be covered by the allocation received from IUGG. However, the funds needed for these expenses have normally exceeded the IUGG allocation, so the organization hosting the SG and thereby the Central Bureau contributes to the travel expenses of the SG and the running of the Central Bureau.

The nominated SG should be prepared to spend at least 1 full day per week on IAG matters, and the Central Bureau hosting organization should provide secretarial assistance equivalent to 2 full days per week. A nomination should therefore include information about the degree to which the hosting organization is prepared to cover, in whole or in part, the expenses of the SG and of the Central Bureau.

The proposal should be submitted to the president of the Nominating Committee, Prof. F. Sansò in electronic form. Proposals may be submitted by the adhering bodies of the member countries, officers, fellows, and members of the Association. Candidates shall be asked to signify their acceptance of nomination and to prepare a resume (maximum 150 words) outlining their position, research interests and activities relating to the Association. The proposal should also state the preparedness to host the Central Bureau, and the financial and secretarial support which may be allocated.

Proposals should be submitted before September, 15, 2006.

Extract from By-Laws:

2.5.3 The SECRETARY GENERAL, shall have the following duties:

a) Serve as secretary of the General Assembly, the Council, the Executive Committee and the Bureau; arrange for meetings of these bodies, distribute promptly the agenda and prepare and distribute the minutes of all their meetings.

b) Director of the Central Bureau.

c) Manage the affairs of the Association, attend to correspondence, and preserve the records.

d) Circulate all appropriate information related to the Association.

e) Prepare the reports of the Association's activities.

f) Perform such other duties as may be assigned to him by the Bureau.

Call for Nomination for IAG positions in the period 2007-2011

To the IAG National Correspondents, IAG Individual Members, IAG Officiers and IAG Fellows

Dear friends and colleagues,

after the Scientific Assembly of IAG in Cairns, our President Gerard Beutler, having taken advice from the Executive Committee (EC), has appointed a Nomination Committee (NC) to implement the procedure of elections of EC members, for the period 2007-2011.

The NC for these elections is composed by

L.P. Fortes (Brazil)

R. Rummel (Germany)

F. Sansò (Italy)

C.R. Wilson (USA)

The voting procedure, after the IAG By-Laws adopted in 2001 ( http://www.iag-aig.org/index.php?tpl=text&id_c=43&id_t=19 ), will be carried out by Council members by mail and should be accomplished by the beginning of June 2007.

Votes will be expressed on a list of candidates, the compilation of which is the main duty of NC.

Such a list will be created in two steps:

Step 1: after the largest consultation of adhering bodies of the member countries, IAG officials, fellows and members, a preliminary list for all the available positions will be created, considering the most frequently suggested candidates;

Step 2: Council members will be informed of the preliminary list, so as to allow National Delegates to propose further candidates, according to the enclosed By-Laws. A final list is then created to be submitted to the vote of Council.

The positions to be filled in are the following:

Post

Present holder

IAG President

G. Beutler

IAG Vice-President

M. Sideris

Secretary General

C.C. Tscherning

President of Commission 1 (Reference Frames)

H. Drewes

President of Commission 2 (Gravity Field)

C. Jekeli

President of Commission 3 (Earth Rotation and Geodynamics)

V. Dehant

President of Commission 4 (Positioning and Applications)

C. Rizos

Members at large (2)

L.P. Fortes

C. Merry

Service representatives (3)

R. Neilan

M. Rothacher

H. Schuh

President of Communication and Outreach Branch (COB)

J. Adam

Let us remember that President, Vice-President and Secretary General cannot be re-elected for the next period; in addition IAG By-Laws (1.2.1) claim “Commission Presidents and Vice-Presidents shall serve in general for one four-year period. Re-elections are possible in exceptional cases”.

The procedure to nominate the Secretary General and the President of the COB involves a direct negotiation with supporting institutions and as such will be directly treated by the Bureau. The nomination of Service representatives will also follow a slightly different procedure involving consultation of Service bodies.

For all the other positions (President, Vice-President, 4 Commission Presidents and 2 Members at large), as a rule, at least 2 candidates should be proposed; for this reason we require to you to send to the following address

elena.raguzzoni@polimi.it

your nomination for one candidate for each post. Of course your list doesn’t need to be complete, in case you prefer so. Your list has to be submitted not later than June 30, 2006. From all the nominations, the preliminary list with 2 candidates per post will be created.

Please consider that the new election procedure has several technical advantages, but specially it has a great value in that it raises the degree of internal democracy of the International Association of Geodesy.

The participation of all members to the fundamental choices of our Association is the unique fuel that can foster an increasing will of international cooperation in our scientific work, which seems to us an essential choice in these times of strong international competition.

So please send us your answer, also considering that it is not necessary to wait the last minute; be sure that we will be happy to follow your indications.

For the Nomination Committee, the Chair,

Fernando Sansò
