Input for next SCOSTEP programafter CAWSES‐II
Japanese SCOSTEP committeeof Science Council of Japan
(Chair: Prof. Tatsuki Ogino, Nagoya Univ.)
Dec 25, 2012Dec 28, 2012 rev.B
Suggested topics for new Task GroupsSOLAR VARIABILITY• Earth‐affecting solar transients
– See appendix 2
• Extreme events in the solar‐terrestrial system• Solar maximum and declining phase
– 2014‐18 will be the maximum and declining phase of solar activity
• Discrimination of global trends and solar activityCOUPLINGS• Latitudinal coupling in atmosphere and geospace
– e.g. energy transfer from high to low latitude during geomagnetic storm– Coupling between equatorial and mid‐latitude/polar ionosphere – Atmospheric coupling between different latitudes and hemispheres
• Whole atmosphere and geospace coupling– Expansion of TG‐4/CAWSES‐II to global scale and into geospace– Effect of geospace disturbance to the atmosphere
IMPORTANT ISSUES• Turbulence/small scale processes in solar‐terrestrial phenomena
– A new issue arising from high‐resolution observation and modeling
• Combination of observation and modeling (in space weather)– Data assimilation for precise forecasting
• Atmospheric dynamics for ground‐ionosphere electric currentINFRASTRUCTURE• Capacity Building• Informatics including big data.
Keywords for the titleof next SCOSTEP program after CAWSES‐II
• No ‘CAWSES‐III’, but the basic concepts of CAWSES should continue.
• Climate, Weather, and Impact • Extreme, Severe, Space storm • 5 year project is preferable
Help for wording needed from English‐speaking members.
(appendix 1) Possible large‐scale projects expected in 2014‐2018,
which Japanese group will organize or join
• Solar Telescope (Kyoto Univ.) • ERG satellite for radiation belts (launch: 2015)• Hinode will keep its operation • IUGONET (database development activity) • PANSY radar will be in full operation in Antarctica • EISCAT‐3D will be in operation (international collaboration) • Equatorial atmosphere radar is newly proposed. • Multi‐point ground network will expand to subauroral
latitudes and Asia/Africa • International school activity will be kept by Kyoto Univ. and
Kyushu Univ.
(appendix 2) CAWSES‐ISEST ProjectInternational Study for Earth‐Affecting Solar Transients (ISEST)
SOC Members: Jie Zhang (USA), B. Vr?nak (Co‐Chair, Croatia), A. Asai (Japan), P.Gallagher (Ireland), A. Lara (Mexico), N. Lugaz (USA), C. Mostl (Austria), A. Rouillard(France), N. Srivastav (India), Y. Yermolaev (Russia), Y.‐M. Wang (China), D. Webb(USA)
An international effort including observations, data analysis , modeling, and transitionfrom science to prediction operation. The ISEST tasks are(1) Create a comprehensive database of Earth‐affecting solar and heliospherictransient events(2) Characterize and quantify the kinematic and morphological properties of transientevents(3) Develop advanced theoretical models of the propagation and evolution ofheliospheric transients(4) Develop advanced 3D numerical models of prediction of ICME arrival and theexpected strength of space weather impact(5) Prediction tool development(6) Public outreach and education
Next program interval (2014‐2018) is a solar maximum and declining phase.
Topics on flare/CME/storm can be approached. Possibility toward the solar ground minimum should be explored.

Implementation plan and current situation
The European Strategy Forum on Research Infrastructures (ESFRI) selected the EISCAT_3D for inclusion in the 2008 update of its Roadmap for Large-Scale European Research Infrastructures. Development of the EISCAT_3D started with the EU FP6 funded Design Study (2005-2009) and is now continued with the EU FP7 funded Preparatory Phase (2010-2014).
Norway and Sweden submitted applications towards construction of the EISCAT_3D in 2012 and 2013. Finnish Roadmap proposal including financing is currently planned. The construction cost is about 132MEuro in total.

Equatorial MU radar
We plan to expand the EAR by installing Equatorial MU radar (EMU). The new EMU is the MU-radar class radar that is 10 times more sensitive to the EAR. This plan is included as part of “Japanese Master Plan of Large Research Projects 2011” by Science Council of Japan.
