U N C L A S S I F I E D Slide 2 of 30 Operated by the Los Alamos National Security, LLC for the DOE/NNSA Kick-off meeting – PLASMON Project, Budapest, 14/15 February, 2011 Space Sciences at LANL – (ISR-1) ISR-1: Space Science and Applications Current Areas of Space Physics Research: - Solar Wind dynamics, sun-Earth connectivity, turbulence (ACE, Ulysses, Cassini) - Magnetotail dynamics (MHD modelling) - Energetic Particle Dynamics and data analysis throughout the inner magnetosphere (LANL GEO, GPS, Polar, Cluster, CRRES, upcoming RBSP) - PI on instrument missions at LANL GEO and GPS, RBSP - Co-I on basically all the past inner magnetosphere particle instrumentation (CRRES MEA and HEEF, Polar CEPPAD, Cammice and Hydra, Cluster Rapid, RBSP HOPE) - Inner magnetosphere modelling – DREAM assimilative code, RAM-SCB ring current code, participants in Michigan Space Modelling Framework

U N C L A S S I F I E D Slide 3 of 30 Operated by the Los Alamos National Security, LLC for the DOE/NNSA Kick-off meeting – PLASMON Project, Budapest, 14/15 February, 2011 Current Status – Radiation Belt Electrons Plasmasheet: Source of seed population (convection & impulsive injection) Magnetopause: Possible loss mechanism for intersecting distorted drift paths + outward diffusion Waves: Drifting electrons encounter several possible wave regions - Hiss (loss) inside plasmasphere/plumes, - Chorus (energization) outside plasmasphere, - EMIC (strong loss) at edge of plasmasphere / plumes. - New: magnetosonic waves near equator

U N C L A S S I F I E D Slide 4 of 30 Operated by the Los Alamos National Security, LLC for the DOE/NNSA Kick-off meeting – PLASMON Project, Budapest, 14/15 February, 2011 LANL contributions to PLASMON In Situ particle data from LANL spacecraft and other missions. Provide link to other radiation belt research / modelling efforts – ISSI, NSF GEM, LANL DREAM. Provide validation data from LANL GEO, GPS on in-situ high altitude energetic particle dynamics. Other datasets available: Aerospace HEO, Cluster Rapid. Testing PLASMON plasmasphere model in radiation belt models – metrics and comparisons to previous models.

U N C L A S S I F I E D Slide 5 of 30 Operated by the Los Alamos National Security, LLC for the DOE/NNSA Kick-off meeting – PLASMON Project, Budapest, 14/15 February, 2011 PLASMON contributions to rad-belt modelling Waves play a major role in determining ring current electron and ion dynamics, being agents of both loss and acceleration of particles. Plasmasphere density is the most important controlling agent determining wave propagation, growth and damping, and also the resulting resonances with magnetospheric particles. For any realistic future now-casting or fore-casting system of the radiation belts an accurate representation of the plasma environment needs to be available – in as real-time a fashion as possible. A plasmasphere modelling using ground based resources offers the only realistic path towards this goal.
