55 Scientific Goals 1. Use diverse instrumentation to observe physical parameters that pertain to the global space weather system, as well as its coupling to the Earth s atmosphere, with a special emphasis on the collection of data and information from all latitudes along a meridian circle 2. Cooperate with appropriate space missions with a view toward characterizing the near-earth space weather system as a coupled three-dimensional entity 3. Understand the behavior of the geospace-atmosphere system under conditions of major magnetic storms and particle radiation
56 Scientific Goals 4. Understand the coupling and feedbacks between geospace and the atmosphere in a global context 5. Develop models and numerical capabilities to simulate and predict space weather in the geospaceatmosphere system covered by IMCP 6. Produce space weather information and data products to improve related research in the participating countries and global community 7. Use the collective resources of IMCP to promote awareness, public outreach, and education about space weather.
57 Running method An IMCP Scientific Committee are established to promote and coordinate cooperative activities, by engage in the following activities: Promote space weather monitoring and research through coordinated ground-based observations Support the International Space Weather Initiative (ISWI) and similar international programs Organize biennial IMCP scientific workshops Coordinate collaborative research activities within IMCP, as well as externally.
58 Progress of IMCP Cooperation agreements have been singed between Meridian Project and the above countries: Russian Canada Brazil Australia American(intend) Japan(intend)
59 Summary Meridian Project is a ground-based network program to monitor space environment, which consists of a chain of ground-based observatories with multiple instruments. International collaboration will make it possible to constitute the first complete environment monitoring chain around the globe.
