AE9, AP9 and SPM: New Models for Specifying the Trapped Energetic Particle and Space Plasma Environment
G. P. Ginet,T. P. O'Brien,S. L. Huston,W. R. Johnston,Timothy Guild,Reiner Friedel,C. D. Lindstrom,C. J. Roth,P. Whelan,R. A. Quinn,D. Madden,Steven K. Morley,Yi-Jiun Su +12 more
TL;DR: In this paper, a new set of models, denoted AE9/AP9/SPM, for energetic electrons, energetic protons and space plasma has been developed, which offer significant improvements including more detailed spatial resolution and quantification of uncertainty due to both space weather and instrument errors.
Journal ArticleDOI
Which magnetic storms produce relativistic electrons at geosynchronous orbit
T. P. O'Brien,Robert L. McPherron,Didier Sornette,Geoffrey D. Reeves,Reiner Friedel,Howard J. Singer +5 more
TL;DR: In this article, the authors apply a recently developed statistical technique to produce an hourly time series of relativistic electron conditions at local noon along geosynchronous orbit using several geOSynchronous monitors.
