We review recent advances in the study of the dissociative recombination of molecular ions
with electrons with a primary emphasis on experimental studies. In particular, we focus on …

We have used the Atmosphere Explorer C data base of ion temperature and ion drift
velocities to study the long recognized principle that large scale convection electric fields are …

We have found that anomalous electron temperatures in the disturbed high‐latitude E region
can be quantitatively explained in terms of heating by unstable plasma waves. The electron …

In this paper we present nearly coincident Chatanika radar electron density measurements
and NOAA 6 particle data for a continuous (diffuse) auroral E layer with a peak electron …

The Scandinavian twin auroral radar experiment (STARE) has a demonstrated capability of
providing estimates of the ionospheric electron drift velocities, which are useful for a wide …

Simultaneous data were obtained between the SAFARI HF coherent radars and the EISCAT
incoherent scatter experiment in December 1983. The SAFARI experiment (Scandinavian …

Intense electrostatic waves in the auroral E region have been detected simultaneously on
two payloads launched in a mother‐daughter configuration from Kiruna, Sweden. The data …

We have systematically studied the effects that non‐Maxwellian ion velocity distributions
produce on the ionic part of the spectrum of radar waves incoherently scattered from the …

We have used a mode‐coupling hypothesis to study the nonlinear evolution of E region
irregularities at high latitudes. Conservation of energy and the identification of two distinct …

E-region electron density profiles with high resolution in time and altitude (5 s and 2 km,
respectively) measured by the EISCAT incoherent scatter radar are used to examine the …
