A far ultraviolet imager for the International Solar-Terrestrial Physics Mission
The aurorae are the result of collisions with the atmosphere of energetic particles that have their origin in the solar wind, and reach the atmosphere after having undergone varying degrees ofExpand

Collision frequencies and energy transfer ions
An investigation has been made of ion collision frequencies and energy transfer for conditions of gaseous thermal nonequilibrium. Following the methods of a development devoted to electronExpand

A new model for the interaction of auroral electrons with the atmosphere: Spectral degradation, backscatter, optical emission, and ionization
A new computational model has been created to describe the interaction of auroral electrons with the atmosphere. For electrons of energy greater than 500 eV, continuous energy losses and small angleExpand

Collision frequencies and energy transfer electrons
A study is made of the problem of elastic collisions and energy transfer between gases which have separate Maxwellian velocity distributions. It is shown that the expression for the energy transferExpand

Effect of electric fields on the daytime high-latitude E and F regions
We have obtained solutions of the coupled continuity, momentum, and energy equations for NO+, O2+, and O+ ions for conditions appropriate to the daytime high-latitude E and F regions. Owing to theExpand

Incoherent scatter measurements of E region conductivities and currents in the auroral zone
Data taken by the incoherent scatter radar facility at Chatanika, Alaska, have been used to investigate ionospheric conductivities and electrical currents. During quiet days the conductivities appearExpand

Photoelectron fluxes in the ionosphere
Calculations have been made of photoelectron fluxes and energy spectra in the ionosphere for predawn and sunlit atmospheres, taking account of transport, elastic and inelastic collisions, and energyExpand

Whistler‐mode radiation from the Spacelab 2 electron beam
During the Spacelab 2 mission the Plasma Diagnostics Package (PDP) performed a fly-around of the shuttle at distances of up to 300 meters while an electron beam was being ejected from the shuttle. WeExpand

Convection electric fields and polar thermospheric winds
Use of the qualitative ideas of convection electric fields over the earth's polar regions to demonstrate the importance of ion drag in establishing a thermospheric wind system. Recent measurementsExpand

Joule heating in the high‐latitude mesosphere
The contribution made by Joule dissipation to heating of the daytime high-latitude upper mesosphere is discussed. During solar proton precipitation events in regions of large electric fields, JouleExpand
