International Association of Geomagnetism and Aeronomy

RESOLUTION I

IAGA,
recognizing	the success of observations made during the IEEY (International Equatorial Electrojet Year) project, 1991-1994, with the collaboration of member countries and support from ORSTOM, CEA, CETP, CNET/Telecum, French Ministry of Cooperation, University of Abidjan, PAIGH, and others, and
noting	IEEY's direct contribution to the basic understanding of electrodynamics in the Earth's environmental space,
urges	that related geomagnetic and aeronomic research programmes be maintained or extended at low-latitude sites in the coming decades, with the continued support from member countries and sponsors concerned. CEA: Commissariat à l'Energie Atomique CETP: Centre des Environnements Terrestres et Planétaires CNET: Centre National d'Etude des Télécommunications IEEY: International Equatorial Electrojet Year ORSTOM: Institut Français de Recherche Scientifique pour le Développement en coopération PAIGH: Pan-American Institute of Geography and History

RESOLUTION 2

IAGA,
recognizing	the fundamental need for better understanding of the solar-cycle variation of the middle atmosphere for accurate estimation of anthropogenic changes,
recommends	that an increased commitment be made by national and international agencies to support an enhanced level of research into this problem.

RESOLUTION 3

IAGA,
recognizing	that rock magnetic property data provide an essential framework for Palaeomagnetic research and for the interpretation of crustal magnetic anomalies, and
noting	that existing accumulations of data are large, diverse, and dispersed, urges the establishment of an international database for rock magnetism.

RESOLUTION 4

IAGA,
considering	the rapid progress currently being made in retrieving and compiling existing low-level airborne and marine magnetic anomaly data over large continental and oceanic areas, and
noting	the importance of magnetic anomaly data for geological and tectonic mapping of the Earth's crust,
urges	the compilation and publication of a digital magnetic anomaly map and database of the entire world (land and sea).

RESOLUTION 5

IAGA,
recognizing	the importance of field-surveys and charts for describing the surface magnetic field of the Earth, and
noting	that charts should be updated at least every 10 years to take into account the secular change of the geomagnetic field,
encourages	the relevant agencies from different countries to continue to support field-survey work and the production of new charts for epoch 2000 AD.

RESOLUTION 6

IAGA,
noting	the need for the AE and Dst Indices by the international scientific community for studies of solar-terrestrial physics, and
recognizing	the great contribution of World Data Center C2 for Geomagnetism, Kyoto in producing the Dst and AE Indices,
expresses	deep appreciation for the work performed by this Data Center in producing the AE and Dst Indices, and
urges	that priority be given to deriving a near-real time AE Index by accelerating the acquisition of Russian geomagnetic data through transmission by satellite.

RESOLUTION 7

IAGA,
noting	the importance of data from the four Russian geomagnetic observatories, Dixon, Tixie Bay, Cape Chelyuskin, and Cape Wellen, in the derivation of the AE Index, which plays an important role in investigations of the solar-terrestrial environment, and
recognizing	that the present delay in the derivation of the AE Index is caused by difficulties of digitization of analog data and the lack of rapid transmission of the Russian data,
urges	the responsible Russian agencies and related organizations overseas to cooperate in the maintenance of the four observatories, installation of digital magnetometers at those observatories, and improvement of data transmission.

RESOLUTION 8

IAGA,
recognizing	the central role of geomagnetic observatory data in the study and applications of all geomagnetic phenomena, and
noting	the great value of long, continuous runs of observatory data,
thanks	the individuals, host institutions, and national funding agencies whose commitments contribute to the continuing operation of geomagnetic observatories world-wide, and
considering	them to maintain their efforts.

RESOLUTION 9

IAGA,
encourages	the need to improve secular variation modelling by the addition of ocean-bottom magnetic observatories to obtain a balanced global coverage, and
noting	the high cost and long time needed to develop an ocean-bottom magnetic observatory prototype,
urges	support of research programs aimed at the design, deployment, and running of ocean-bottom magnetic observatories.

RESOLUTION 10

IAGA,
noting	the considerable interest in the effects of the Interplanetary Magnetic Field (IMF) on the geomagnetic field, and
noting	recent advances in measurement and data transfer in near-real time,
encourages	interested institutes to continue their work in the development of indices and similar parameters to describe IMF structure using ground-based and satellite measurements.

RESOLUTION 11

IAGA,
noting	that 15 years have passed since the last high-accuracy vector geomagnetic survey from low-Earth orbit, and
recognizing	that continued accurate measurements of the geomagnetic field and its variations with time are crucial for our understanding of the Earth,
urges	the support of on-going missions and the initiation of new efforts to construct satellites capable of measuring accurately the vector geomagnetic field.

RESOLUTION 12

IAGA,
noting	the explosive increase in the amount of data in geomagnetism and solar-terrestrial physics, and
recognizing	the fundamental importance of the construction of accessible databases,
urges	further support for data centers to acquire the facilities and personnel necessary for efficient data exchange in this new situation.
