What else can we learn with coherent scatter radars about E and F region irregularities that we don’t know? What else can we learn about ESF and midlatitude SF?

Coherent scatter radars have been used since the early 1950s to study the ionospheric E and F region irregularities at all latitudes. Since then, and in particular in last decade, such systems have proliferated around the world with varying degrees of sophistication, complexities and usage, most of them operating in the HF and VHF frequencies. Observations from these systems are currently being used to study the plasma processes behind the echoes, to diagnose the ionosphere region they are embedded in and therefore study the ionosphere electrodynamics, to characterize and forecast (?) the occurrence of scintillation activity, to complement and validate measurements done with other instruments, etc. In this presentation we present a brief overview of how current coherent radars are being used, making emphasis on their main focus and current limitations. Then, as the title and session description indicates, we will present our view of what are the current outstanding questions, how coherent radars will be and should be used in the future depending on the different research and/or operational objectives
