Solar Wind Flux: Electron/Proton Count Reaching Earth

Click For Summary
SUMMARY

The solar wind flux reaching Earth consists of approximately 10 particles per cubic centimeter (particles/cc), which includes both electrons and protons. NASA/Goddard is the primary agency responsible for collecting and analyzing data on solar radiation and its effects. Key resources for further information include the MIT Wind Plot and NASA's educational materials on solar wind. Understanding the local density of solar wind is crucial for comprehending its impact on systems and personnel.

PREREQUISITES
  • Basic understanding of solar wind dynamics
  • Familiarity with particle density measurements
  • Knowledge of NASA's solar radiation research
  • Awareness of the effects of radiation on systems and personnel
NEXT STEPS
  • Explore NASA's solar wind data collection methods
  • Investigate the implications of solar wind on satellite operations
  • Learn about the instruments used in solar wind measurement, such as ACE and WIND
  • Research the relationship between solar wind and space weather phenomena
USEFUL FOR

Astronomers, space weather researchers, and professionals involved in satellite technology and radiation safety will benefit from this discussion.

can anyone give me the flux of solar wind reaching earth...the number of electrons/protons /cm^2/sec reaching Earth from Sun...i searched many sites but couldn't get the value...

I think NASA/Goddard is the primary agency for collecting data on solar radiation. They do a lot of research into the effect of radiation on systems and personnel.

It looks like the local density is about 10 particles/cc. Electrons and protons (alphas) are electrically neutral on a macroscopic scale. The coulomb forces simply enforce electrical neutrality.
