The applied models within SPENVIS are chosen according to the relevant European ECSS standard, i.e. AP-8 at minimal solar activity for protons and AE-8 at maximum solar activity or IGE for electrons in LEO or GEO, respectively. Solar protons were modeled with the ESP model at 95% confidence level. The lower energy range of the AP-8 and ESP. CCMC Services available for AE-8/AP-8 RADBELT. A software package that includes (1) an improved and updated version of the old MODEL program (MODEL87), (2) an interactive driver program (RADBELT), (3) the electron AE-8 and proton AP-8 flux maps for solar maximum and minimum, and (4) the interpolation subroutines.
This graphic of the solar system was made using real images of the planets and comet Hale-Bopp. It is not to scale! To show a scale model of the solar system with the Sun being 1cm would require about 64 meters of paper! Image credit: Maggie Mosetti, NASA. This book was produced to commemorate the Year of the Solar System (, a martian. ( R E) at midnight may measure electrons on a drift shell that corresponds to L = 7, while a geosynchronous satellite at noon may measure electrons on a drift shell closer to L = 5. The radial flux profile of radiation belt electrons, whose maximum is usually around L = 4, has a peak closer to geosynchronous orbit on the dayside. As a.

Parameter: Trapped electron and proton fluxes in Earth's radiation belt Brief Description: These maps contain omnidirectional, integral AE 6 (AE maps) and proton (AP maps) fluxes in the energy range MeV to 7 MeV for electrons and MeV to MeV for protons in the Earth's radiation belt (L = to 11 for electrons, L = to 7 for protons).

[Michael J Teague; King W Chan; James I Vette; National Space Science Data Center.; World Data Center A for Rockets and Satellites.]. A projected inner zone electron model environment, AE 6, for the epoch is presented.
It is intended to provide estimates of mission fluxes that spacecraft will encounter in the coming solar maximum years. AE 6 is presented by graphs of omnidirectional integral flux as a function of L shell, the ambient magnetic field B, and the energy E.
Results of orbital integrations for altitudes Cited by: AE 6 is presented by graphs of omnidirectional integral flux as a function of L shell, the ambient magnetic field B, and the energy E. Results of orbital integrations for altitudes from n.m. to 18, n.m. are given for circular orbits with four different inclinations, using the AE 6 and the AE 4 solar maximum models for the inner and outer Author: M.

It can be seen from Table 1 and Table 2 that the AE-8 MIN and AE-8 MAX densities at L= are comparable to those obtained in around the minimum between solar cycles 21 and However, the values of the characteristic temperatures derived from AE-8 are higher by a factor for the soft electrons and a factor for the hard electrons.

Note2: Parameters values must be entered in the order of increasing magnitude starting with the lowest value and ending with the highes value.
Energy values: (Range of values for Electrons is from to 7. Mev; for Protons from to This model was based upon data from eight satellites and was used to reduce all data to the form of equatorial flux. Although no Starfish-free high energy electron measurements were available from the inner portion of the inner radiation zone, it was found that the AE-6 model provided a good description of the present solar maximum environment.
The AE-8 environment is an update of the old AE-4 model using geosynchronous data from ATS 1, 5, and 6 and extreme extrapolations up the field line of low altitude data from OV, OV, and AZUR.
The AE-4 model was known to be inaccurate, but it was the best available. Space Radiation Environment Trapped Particles Protons, Electrons, Heavy Ions after Nikkei Science, Inc.

To address this challenge a new set of models, denoted AE9/AP9/SPM, for energetic electrons, energetic protons and space plasma has been developed. The new models offer signiﬁcant improvements including more detailed spatial resolution.

and Western Europe are AE-8 for electrons of energy greater than 40 keV and AP-8 for protons of energy greater than MeV (Vette, ). satellites in three solar cycles, which allowed the model to predict a wide range of energy, from 1 MeV to above MeV. The SEPs were estimated during a solar maximum and a magnetic storm.
Finally, NASA models AP-8 and AE-8 were selected to generate fluxes of trapped protons and trapped electrons, respectively. 6 Space Radiation Effects on Electronics presented by Kenneth A.

Regions of stable existence of radiation belts are obtained analytically by generalizing the Størmer theory to the case of an axisymmetric quadrupole. An reversal scenario is proposed in which it is shown that a.
