★ [PEM10-24] Advancing Research of Coupling between Geospace Environment and Atmosphere by the EISCAT 3D Incoherent Scatter Radar
Keywords:incoherent scatter, geospace environment, atmosphere, dynamic coupling, high-energy particle precipitation, chemistry of atmosphere
The new EISCAT 3D phased-array facility, to be built in near future, will be a 3-dimensionally imaging radar, distributed in Norway, Sweden, and Finland. It will surpass all the current IS radars of the world in technology and act as a pathfinder for other types of radar facilities worldwide. EISCAT 3D will make continuous measurements of the geospace environment and its coupling to the Earth's atmosphere in the polar region and at the southern edge of the polar vortex for the next 30 years. Planning of the new IS radar facility started with the EU-funded Design Study (2005-2009). In December 2008, the European Strategy Forum on Research Infrastructures, ESFRI, selected EISCAT 3D to the Roadmap for Large-Scale European Research Infrastructures. The preparation continued in the EU FP7 Preparatory Phase project (2010 - 2014). Currently EISCAT Scientific Association has applied EU financing in order to study together with manufacturers, the industrial implementation of the technical solution for EISCAT_3D. Construction of EISCAT 3D can start as soon as the international financing for EISCAT_3D will be in place.
The EISCAT 3D will be realised as a multi-sited infrastructure using phased-array antennas and a key aspect is the use of advanced software and data processing techniques. The science case of EISCAT 3D includes studies of atmospheric physics and global change, space and plasma physics, solar system research, space weather and other service applications, development of new radar techniques, and methods for coding and analysis. Here we give a summary of the planned characteristics and science goals of the proposed international research infrastructure, review the current status of preparations towards realizing EISCAT 3D, and give a more detailed perspective to one of the key science themes of EISCAT 3D: Coupling between geospace environment and atmosphere of Earth during high energy particle precipitation into the atmosphere.
