Imaging radar observations and nonlocal theory of large-scale plasma waves in the equatorial electrojet

open access: yes, 2002
International audienceLarge-scale (l ~ 1 km) waves in the daytime and night-time equatorial electrojet are studied using coherent scatter radar data from Jicamarca.

Rocket experiments for spectral estimation of electron density fine structure in the auroral and equatorial ionosphere and preliminary results [PDF]

open access: yes
Sounding rockets equipped to monitor electron density and its fine structure were launched into the auroral and equatorial ionosphere in 1980 and 1983, respectively. The measurement electronics are based on the Langmuir probe and are described in detail.

Auroral effects in the D region of the ionosphere [PDF]

open access: yes
The possible effects are discussed of radiations and corpuscles on relatively short-term changes in the circulation of the atmosphere (the development of cellular patterns in the zonal westerly flow, leading to the formation of cyclones) and relatively ...

The International Equatorial Electrojet Year

open access: yesEos, Transactions American Geophysical Union, 1992
During its sixth scientific assembly in Exeter, United Kingdom, the International Association of Geomagnetism and Aeronomy (IAGA) designated September 1991–March 1993 as the International Equatorial Electrojet Year (IEEY). During this period, intensive and coordinated campaigns on the equatorial electrojet (EEJ) and related aeronomic phenomena are ...

The Electromagnetic Characteristics of the Polar Ionosphere during a Moderately Disturbed Period [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1995
The distribution of the ionospheric conductivities, electric potential, ionospheric currents, filed-aligned current, Joule heating rate, and particle energy input rate by auroral electrons along with the characteristics of auroral particle spectrum are ...

The response of ionospheric convection in the polar cap to substorm activity

open access: yesAnnales Geophysicae
We report multi-instrument observations during an isolated substorm on 17 October 1989. The EISCAT radar operated in the SP-UK-POLI mode measuring ionospheric convection at latitudes 71°λ-78°λ.
