Antarctic space-related research
successful exploration of the solar-terrestrial environment. The active injection of VLF waves from the ground, notably in the Antarctic at Siple Station, has become a powerful tool for studying and understanding the complex non-linear processes that determine the high levels of ELF/VLF (Extremely Low Frequency/Very Low Frequency) noise in the magnetosphere which in turn affect and control the dynamics of the Earth’s radiation belts. Studies of the Earths space environment are now entering a new era of coordinated and comprehensive investigations, as represented, for example, by the NASA/ESA/ISAS/INTERCOSMOS/GGS/ISTP (Global GeospaceScience/International Solar Terrestrial Physics) programme and the US National Science Foundation’s CEDAR (Coupling, Energetics and Dynamics of Atmospheric Regions) and GEM (Global Environmental Modelling) initiatives. As an element of these new initiatives, SCAR recommends the establishment of an international ELFNLF wave injection facility in the Antarctic. SCAR further recommends that the scientific and engineering requirements for such a new facility be defined in an international workshop to be held as soon as possible, and invites the appropriate national and international agencies to make the necessary funds available for a successful workshop. XX-UAP-5.
SCAR has noted the 1987 URSI Council recommendation (U.21) on the establishment of an Incoherent Scatter and Stratospheric Tropospheric (ISST) radar in Antarctica. SCAR recommends that, if the opportunity arises to construct an ISST radar in Antarctica, it would be advantageous if this were to be done as a collaboration between SCAR nations.

The SCAR Working Group on Human Biology and Medicine established an ad hoc group on Antarctic space-related research to identify and study those mutual problems faced both in polar regions and space environments. The aim is to enhance the performance, health and safety of people in both settings. The Group will be convened by~Dr D. Lugg, chairman of the Working Group, and it will have a sufficient number of interdisciplinary and international members to ensure its continuity. The purpose is to formulate a series of viable research projects as would be appropriate and of mutual benefit for science in Antarctica, outer space and other challenging environments. The projects may involve existing summer, (“‘)From SCAR Bulletin No. 92, January 1989.

winter and traverse groups, and potential simulated space stations in Antarctica. The group will establish active channels of communication among members to identify the facilities and support, and to determine methods and procedures for productive operational research. Progress will be reviewed at the XXIst SCAR Meeting. All present indications are that the major Antarctic research groups, and the major space groups would welcome the proposal.
4.10 WORKING GROUP ON GLOBAL CHANGE AND GEWEX
During the Vancouver General Assembly of the International Association of Hydrological Sciences, its International Committee on Remote Sensing and Data Transmission (ICRSDT) established a Working Group on Global Change and the Global Energy and Water Cycle Experiment (GEWEX). The present members are: Barry Goodison (Canada), Robert Gurney (USA), Helmut Rott (Austria), Albert Rango (USA), Vincent S~omonson (USA) (Chairman) and John Stewart (UK). Provisional effort areas to be considered and developed include: (a) Further definition of the role of remote sensing and data transmission in GEWEX. @) Definition of the large-scale effects of seasonal snow cover, particularly as observed by remote sensing. (c) Quantifying the spatial and temporai variability of evapotranspiration over large areas using remote sensing. (d) Selection of models making good use of remote sensing for use in general circulation models and water balance studies. (e) Definition of methods involving remote sensing or data transmission to aggregate observations or parameterize processes on a regional scale (e.g., GCM grid scale: 100X100 km) so as to link local processes with GCM models of the atmosphere or large watershed models. (f) Developing recommendations for remote sensing and in situ data sets that should be given high priority and compiled for studies of the hydrological cycle and its evolution over time. As part of this reco~endation, identification of key countries and their existing data sets might be included in the effort. Those who would like to collaborate with this working group, or who have suggestions that the working group should consider, are encouraged to contact: Dr Vincent V. Salomonson, Chief, Laboratory for Terrestrial Physics, NASA/Goddard Space Flight Center, Greenbelt, MD 20771, USA.
