1.15. IAU SYMPOSIUM No. 128: EARTH’S ROTATION AND REFERENCE FRAMES FOR GEODESY AND GEODYNAMICS”6’
Coolfont Resort, Berkeley Springs, West Virginia, USA, 20-24 October 1986 This symposium was held at Coolfont Resort in Berkeley Springs, West Virginia, USA, 20-24 October 1986. The meeting was attended by 126 people from 17 countries. Support was provided by the US Naval Observatory, National Geodetic Survey, Naval Research Laboratory and Defense Mapping Agency. The Scientific Organizing Committee comprised D. McCarthy (Chairman, USA), M. Feissel (France), J. Kovalevsky (France), I. Mueller (USA), D. Robertson (USA), G. A. Wilkins (UK), Y. S. Yatskiv (USSR), Ye Shu-hua (China PR), K. Yokoyama (Japan). The Local Organizing Committee included W. Carter (Chairman, USA), A. Babcock, K. Johnston, D. McCarthy, G. Westerhout and W. Wooden. Sessions were devoted to: Celestial reference frames, Terrestrial reference frames, Possible future improvements in the concepts and realization of reference frames, Laser ranging, VLBI, Observations of Earth rotation parameters, Nutation and precession, Combination and prediction of Earth rotation parameters, Predicting Earth orientation, Geophysical interpretations. Several working groups also held meetings during the week: the IAU Working Group on Reference Frames, the Provisional Directing Board of the IERS, and the IAG Special Study Group on the Relationship between Atmospheric Angular Momentum and the Rotation of the Earth. Four resolutions were adopted. The proceedings of the Symposium are to be published by Reidel and edited by George Wilkins and Alice Babcock.
