Storm-dependent radiation belt electron dynamics
[1] Using recently published electron phase space densities (PSD) as a function of L* (L* is approximately the radial distance in Earth radii at the equator) and time, energization and loss in the Earth’s outer electron radiation belt were studied quantitatively and numerically using a radial diffusion model that included finite electron lifetimes and an internal source parameterized as a funct...
متن کاملRadiation belt electron precipitation into the atmosphere: Recovery from a geomagnetic storm
[1] Large geomagnetic storms are associated with electron population changes in the outer radiation belt and the slot region, often leading to significant increases in the relativistic electron population. The increased population decays in part through the loss, that is, precipitation from the bounce loss cone, of highly energized electrons into the middle and upper atmosphere (30–90 km). Howe...
متن کاملUnraveling the drivers of the storm time radiation belt response
We present a new framework to study the time evolution and dynamics of the outer Van Allen belt electron fluxes. The framework is entirely based on the large-scale solar wind storm drivers and their substructures. The Van Allen Probe observations, revealing the electron flux behavior throughout the outer belt, are combined with continuous, long-term (over 1.5 solar cycles) geosynchronous orbit ...
متن کاملGlobal storm time depletion of the outer electron belt
The outer radiation belt consists of relativistic (>0.5 MeV) electrons trapped on closed trajectories around Earth where the magnetic field is nearly dipolar. During increased geomagnetic activity, electron intensities in the belt can vary by orders of magnitude at different spatial and temporal scales. The main phase of geomagnetic storms often produces deep depletions of electron intensities ...
متن کاملElectron Lifetimes in the Outer Radiation Belt
3 Data assimilation aims to smoothly blend incomplete and inaccurate ob-4 servational data with dynamical information from a physical model, and be-5 come an increasingly important tool in understanding and predicting me-6 teorological, oceanographic and climate processes. As space-borne observa-7 tions become more plentiful and space-physics models more sophisticated, 8 dynamical processes in ...
