Polar Ionospheric Research

Аннотация

Defines the ionsphere and describes its three horizontal layers or regions, distinguished by physical characteristics and ionization processes: as quiet D, E and F regions and as disturbed D, E and F regions when there is a disturbed sun (sunspot magma). Representative research techniques are characterized: all-sky camera, auroral spectroscopy, ionosonde, riometer, VHF forward scatter, auroral radar, whistlers, balloons and rockets. Some of the research problems are: the magnetospheric model, auroral theory, and the polar substorm. Programs needed include routine recording, a polar meridian net and experiments utilizing satellites and rockets, all of which can use support of the Naval Arctic Research Laboratory at Barrow, Alaska.
