Title For decades several attempts have been made by ICSI to promote all Cryospheric Sciences and to elevate the study of the Cryosphere to a more prominent position within the International Union of Geology and Geophysics, from a Commission within IAHS to a separate Association under IUGG. In the mean time IUGG/CCS is governed by the former ICSI statutes, wherever they apply to a Union commission, and by the guidelines provided by IUGG for its Union Commission. This means that a set of statutes for the new Association is under construction that will adhere to the IUGG standards for such an Association. www.glaciologi.su.se /ICSI

ORGANIZATIONAL FRAMEWORK Scientists who study the Earth including its surrounding hydrosphere and atmosphere, have formed two international unions: the IUGG-International Union of Geodesy and Geophysics (IUGG) and the International Union of Geological Sciences IUGG-International Union of Geological Sciences. IAVCEI is one of the seven, and the International Association of Seismology and the Physics of the Earth's Interior (IASPEI) is another. The International Association of Volcanology (IAV) was founded in 1919 and was the forerunner of IAVCEI. www.iavcei.org /organizational_framework.htm   (493 words)

IAU / Descartes Prize The IAU/IUGG "Nutation" Working group was established in 1994 with the aim to come up with an improved model relating the precession and nutation of the Earth to the sophisticated non-rigid Earth. The "IAU 2000 model" was formally adopted by the IAU in July 2000 and by the IUGG in July 2003 and the International Earth Rotation and Reference Systems Service (IERS) is now implementing it in all astrometric and geodetic techniques. The IAU has the pleasure to announce that the "European Descartes Prize" was received in 2003 by the group "Nutation" that formed the European part of a joint Working Group of IAU and IUGG called "Non-rigid Earth Nutation Theory". www.iau.org /IAU/News/descartes.html   (493 words)

1999 Informal Publications IUGG 99 Abstracts Week B, IUGG XXII General Assembly, Birmingham Univ., U.K., July 18-30, B.276. This scenario explains many observed features of severe storms, and leads to the conclusion is that the rain curtains associated with hook-shaped appendages to radar echoes are the instigators (not just passive indicators) of tornadoes. The cyclonic spin is greatly amplified if the air on the left side passes out of the downdraft along the ground into an updraft. www.nssl.noaa.gov /papers/informal/1999other.html   (118 words)

General Meeting Minutes Appendices 1-3 It is scheduled for Sunday, 25 July 1999, in a yet unspecified room on the campus of Birmingham University during the IUGG-99 General Assembly. New results from the IPEI payload are being presented in the 1999 Spring AGU meeting in Boston, the CEDAR 1999 meeting in Boulder, and the IUGG 99 Assembly in Birmingham. Since the pressure generally decreases and the entropy function S increases tailward, the diffusion of plasma pressure results in a steepening, or antidiffusion of the entropy profile. www.ngdc.noaa.gov /stp/SCOSTEP/Genapp1-3.html   (211 words)

Article of the Month - July 2004 The replacement of the fundamental star catalogues by a catalogue of Quasars for the definition of the celestial reference frame (surprisingly accepted by both, the IUGG and the IAU in the 1990s) was an epochal event (which passed, however, almost unnoted by the larger scientific community). Furthermore it was not the IPMS which embraced the new space techniques, and this mandate was then given to an IAU/IUGG joint working group in 1978. It proved that a system based on the measurement of the Doppler shift of signals generated by stable oscillators on board satellites could be used for positioning with a remarkable accuracy (0.1-0.5 m relative, about 1 m absolute). www.fig.net /pub/monthly_articles/july_2004/beutler_july_2004.htm   (211 words)

ROB : WG : Non-Rigid Earth Nutation Theory Establishes an inter-commission Working Group on the non-rigid Earth Nutation Theory to be organized by the Presidents of Commissions 4, 7 and 19, under the leadership of V. Dehant, and Invites the IUGG to join the IAU in sponsoring this Working Group in order to form a joint IAU/IUGG Working Group on this topic. Since there are large differences between the IAU 1980 adopted nutation theory and the observed series of nutation, a WG has been created in 1994 of which to task was to evaluate the possibilities of building a new geophysical nutation theory, a new "non-rigid Earth nutation theory". (1) the input seismic model, (2) the Earth's transfer function, (3) the rigid Earth nutations (4) the convolution between the non-rigid Earth's transfer function and the rigid Earth nutations, and (5) the additional corrections for ocean and atmosphere effects on the nutations. www.astro.oma.be /D1/EARTH_ROT/wgnut.html   (211 words)

ITRF - GPS The ITRF94 scale fixing is based on a weighted average of a selection of VLBI, SLR and GPS solutions on one hand, and on the other hand it is consistent with the IUGG/IAU resoultions related to the definition and realization of the International Terrestrial Reference System. In order to define a terrestrial reference frame, in a specific data analysis, four datum components (orientation, origin, scale and time evolution) should be clearly defined. The ITRF is established by the Terrestrial Reference Frame Section of the Central Bureau (CB) of the International Earth Rotation Service (IERS). schubert.ign.fr /CIAG/WITRF/ITRF-GPS.html   (211 words)
