    Slide 7:Solar Models

    Potential Field Source Surface (Luhmann, UCB) - Global solar magnetic field structure MAS (Linker et al – SAIC) – Global solar magnetic field and plasma structure Operational significance: Now: Solar wind, connection to active regions (solar energetic particles) Future: Solar eruptions, CMEs P. MacNeice, L. Rastaetter Density, flows

    Slide 8:Solar/Heliospheric Models

    WSA (Wang-Sheeley-Arge) – Corona + empirical/kinematic solar wind Operational significance: Solar wind forecasting P. MacNeice

    Slide 9:Heliospheric Models

    ENLIL (Odstrcil – NOAA) – Complete, physics-based, heliosphere ( 30rs – 10AU) Heliospheric Tomography (Jackson,Hick – UCSD) Operational significance: Now: Solar wind forecasts, connection to active regions (solar energetic particles) Future: Solar eruptions, CMEs, higher fidelity forecasts P. MacNeice, L. Rastaetter, M. Kuznetsova, A. Chulaki

    Slide 10:Forecasting : Sun to Earth

    Decision makers and operational agencies need model evaluations - Science-based validation: Compare model output to measurements for select events, detailed analysis - Metrics studies: Repeatable comparison between model output and measurements, “one number” Need to be blind studies, performed by independent agent Transition to Operations: V&V and Metrics V&V: Simulate Polar Cap Size open FL closed FL Boundary between open and closed field lines (FL) open FL VIS Earth Camera 15 July 2000 20:20 UT Polar cap boundary observed by POLAR V&V: Simulate Polar Cap Size Rastaetter et al., 2005 V&V/R&D: Radiation Belt Modeling Los Alamos National Laboratory Satellite Data Improved Model Original Model 50 - 75 keV 75 - 105 keV 105 - 150 keV 150 - 225 keV 225 - 315 keV 315 - 500 keV 500 - 750 keV 0.75 - 1.1 MeV 1.1 - 1.3 MeV flux increase flux decrease/flat A.

    Slide 21:Support the generation of advanced space science models Address Space Weather-relevant processes Collaborate with related activities (CISM, CSEM, ILWS…) Expand strong service to (international) research community Execute runs-on-request Provide ready access to model output with enhanced tools Includes mission support, e.g., STEREO Includes campaign support, e.g., IHY

    Future Activities: Research Support

    Slide 22:Future Activities: Operations Support

    Provide tool by which science progress at NASA, NSF feeds into Space Weather operations Focus on science models with operational benefits Operator input to identify model needs Address immediate payoffs as well as strategic value models (e.g., solar forecasting) Provide expanded, independent model evaluations Obtain metrics, V&V procedures from operators Support GAIM V&V Perform priority evaluations for operations Provide rapid response service in emergencies Other opportunities for closer collaborations/tailored support Education: Coordination initiated with AFIT, USAFA Interacting with AFWA (LtCol. Cade, Maj. Nobis) Implementation: Installation design and support possible Tool development following operator needs CCMC ready to explore new ways to support
