THE IACG AND ASSOCIATED CAMPAIGNS (ref. 1,2,3)

In 1981 the space agencies of Europe, the former USSR and Eastern European countries, Japan, and the United States of America formed the Inter-Agency Consultative Group for Space Science (IACG) to provide a framework for enhancing scientific cooperation among their respective agencies: the European Space Agency (ESA), Space Research Institute (IKI), the Institute of Space and Astronautical Science (ISAS), and the National Aeronautics and Space Administration (NASA). The IACG mission coordination is primarily achieved through conducting specific campaigns, each of which has a definitive scientific focus. There are currently four IACG campaigns in the planning or implementation stage:

IACG Campaign I: Magnetotail Energy Flow and Non-Linear Dynamics
IACG Campaign II: Boundaries in Collisionless Plasmas
IACG Campaign III: Solar Events and Their Manifestations in Geospace
IACG Campaign IV: Solar Sources of Heliospheric Structure Observed Out of the Ecliptic

A "Campaign" involves the coordinated collection, analysis, interpretation, and eventual publication of core and ancillary data sets from multi-spacecraft and ground based observations covering limited time periods to achieve specific scientific objectives. Aspects of a campaign include: determination of campaign objectives, identification of key observing time periods, identification and coordination of required data sets, and coordination of data analysis.

IACG CAMPAIGN IV OVERVIEW

The purpose of IACG Campaign IV Solar Sources of Heliospheric Structure Observed Out of the Ecliptic is to plan the international coordination of solar and heliospheric observations during mid-1994 through 1996 covering the ESA/NASA Ulysses spacecraft's pass over the southern polar region of the sun, the perihelion pass across the solar equator, the northern polar pass, and the northern hemisphere descent. This extensive collaborative work potentially involves solar observations by the Yohkoh spacecraft, Ground-Based Observatories, the SOHO and Coronas spacecraft, and the Spartan Space Shuttle missions, and in-situ. observations by the Ulysses, IMP-8, SAMPEX, Voyagers, Pioneers, Wind, and ICE spacecraft. A coordinated effort with theoreticians and modelers is also required for the successful completion of the campaign objectives.

IACG CAMPAIGN IV OBJECTIVES (ref. 3)

At the First IACG Solar-Heliospheric Workshop on "Solar Sources of Heliospheric Structure Observed Out of the Ecliptic" (Easton, MD, January 1994), four major science topics were identified:

Large Scale Heliosphere and Its Dependence on Solar Photospheric and Coronal Phenomena
Topology of Coronal Streamers
Three-Dimensional Shape of Coronal Hole Boundaries
Solar Wind Source and Acceleration

Within these major topics, several subtopics emerged, such as

The structure of the heliospheric magnetic field as a function of heliolatitude, and its relation to coronal structure
The determination of the strength and structure of the photospheric magnetic field in the polar regions of the sun
The structure, dynamics, and heliolatitude extent of transient phenomena, such as Coronal Mass Ejections from the sun and their manifestations in interplanetary space
The dependence of the solar wind and its properties on the topology and dynamics of polar coronal holes
Tests of solar wind acceleration models and their dependence on solar coronal field geometries
The heliolatitude dependence of the properties of the solar wind, in particular its relationship to open and closed coronal structures, and the origin of the slow solar wind
North-South asymmetries of the Sun at solar minimum, and a search for the axes of symmetry of the two hemispheres of the Sun
The extent and structure of the heliospheric current sheet and its relationship with the solar magnetic neutral lime, as well as its relationship with the heliospheric extension of the coronal streamer belt

Comments/Suggestions:

This homepage is obviously still under construction.

We (Hugh Hudson and Toni Galvin, the Campaign IV Leaders) want suggestions from the Ulysses, Yohkoh, Ground Based, and other interested communities, regarding the content, format, and implementation (including management and data distribution) of the campaign. We want to utilize the experience and expertise of individual members of the interplanetary, solar, and modeling/theory communities.

We would like interested parties to contact us
