Results of Artificial Ionospheric Turbulence Studies Using the ISR and SEE Techniques at the Arecibo Low-Latitude Heating Facility

We report preliminary results of the Arecibo heating campaign in November 2018. Different methods for studying artificial plasma turbulence were used concurrently, namely the incoherent scattering radar (ISR) and stimulated electromagnetic emission (SEE) techniques. The aim of the experiments was analyzing HF-induced plasma turbulence evolution for short and long time of ionosphere modification above the low-latitude heating facility in view to investigate a competition between the Langmuir and upper-hybrid plasma turbulence.
