We performed experiments using the 50-MHz Jicamarca radar to study the equatorial 3-m scale plasma irregularities which are responsible for the radar backscatter called 15-km echoes observed at upper E-region heights from approximately 140 to 170 km. These studies were motivated by the search for a ...

Incoherent scatter (IS) radar and ionosonde (VIPIR, vertical incidence pulsed ionospheric radar) data were taken concurrently at Jicamarca during campaigns of January, April, June, and July 2015, January 2016, and most recently April 2017 to bring more insight into the state and dynamics of the ...
