Geographical Distributions of Electrons (0.05-3.2 Mev) and Protons (0.58-35 Mev) at Altitudes of 350-850 Km

摘要

The geographical distributions of high energy electrons and protons are shown. OHZORA satellite data, which were acquired with two delta E x E silicon detector telescopes, are used to show particle distributions for altitude intervals of 350 to 500 km, 500 to 600 km, 600 to 700 km, and 700 to 850 km during the period from February 1984 to February 1985. Three energy and particle groups are illustrated: (1) electrons (0.05 to 0.19 MeV) and protons (0.58 to 3.3 MeV), (2) electrons (0.19 to 3.2 MeV), and (3) protons (0.64 to 35 MeV). Special high flux regions are mapped in the South Atlantic magnetic anomaly and in the auroral zones. The low-latitude particle precipitation zones are not identified during quiet time geomagnetic conditions.
