The purpose of these historical notes is to present the early history of the Jicamarca Radio Observatory (JRO), a research facility that has been conducting observations and studies of the equatorial ionosphere for more than 50 years. We have limited

The instability which arises in thin ionization layers in the ionospheric E region is inherently nonlocal at mid-latitudes because of the high conductivity along the inclined magnetic field lines. We attack the gradient-drift stability problem using

We describe simultaneous radar observations made with the Cornell University Portable Radar Interferometer (CUPRI) at 50 MHz and the Arecibo incoherent scatter radar (ISR) at 430 MHz during the El Coqui campaign of 1992 in Puerto Rico. The goal was t

What follows are some personal recollections of John that I thought might be of interest to some readers of this special issue of the Journal of Plasma Physics.

Incoherent scatter measurements from Jicamarca, Peru, show that current models and cross sections account quite well for the heating and cooling of F region electrons, in marked contrast to earlier similar studies at low and middle latitudes. The lat

Incoherent scatter autocorrelation function measurements are difficult to make in the F región at Jicamarca because of very strong clutter contamination by coherent echoes from unstable plasma waves in the -B-region electrojet that are aligned with

[1] The magnetic aspect angle sensitivity of 3-m plasma density irregularities in the F-region ionosphere over Jicamarca has been measured during the passage of a radar plume in an equatorial spread-F event. The measurement technique utilizes radar i

The plasma instabilities in the low-attitude auroral ionosphere and the sources of free energy that drive these waves have been examined in detail in the framework of the ERRRIS project. Independent sets of experiments were carried out on board three

In the late winter of 1988 and 1989, three NASA sounding rockets were flown through the auroral electrojet from ESRANGE (Sweden) as part of the E-region Rocket-Radar Instability Study (ERRRIS). Many ground-based instruments supported these flights, i
