Ionosphere data

Ionosphere — is a part of upper atmosphere, where the density of unbound electrons is enough to influence the wave transmission. Ionization depends, firstly, on Solar activity.

• Ionosphere data on the site of Russian WDC on Solar-Terrestrial Physics.
• Ionosphere and plasmasphere of the Earth. Distribution of density, temperature and neutron encounters frequency model.
• Ionosphere data of Institute of ionosphere of NTUU «KhPI».
