F-region ionospheric irregularities over King George Island and Argentine Islands – a comparative study
Read more of: F-region ionospheric irregularities over King George Island and Argentine Islands – a comparative studySpread-F is caused by the presence of ionospheric electron concentration irregularities of scale-size of order 5 km at F-region altitudes. Estimates of spread-F in the vicinity of the maximum plasma […]
