dc.description.abstractThe Doppler spectra of amplitude variations for meteor trails and sporadic–E layers have simultaneously been recorded with MST radar at Gadanki during the active periods of Perseid, Leonid and Geminid meteor showers in 2007. The variations of the activities of the radar meteors during the shower periods and the occurrences of E–region irregularities as observed with MST radar are presented in this paper. It has been noticed that the discrete strata of sporadic–E occurring in the altitude range 95–110 km during these shower periods with maximum percentage of occurrence on the nights of peak activities of these meteor showers. The close inspection of radar meteor data reveal the generation of faint Type-1 echo during the peak active period of the Geminid shower with reduced Doppler velocities by 20% at the altitude of 91 km and are found to be imbedded in the strong Type–2. The radar data of meteors are also used to retrieve the temperatures of MLT region.en_US
