The echoing region is confined to 142–162 km altitude and show forenoon descent and afternoon ascent displaying a ‘necklace shape’ quite similar to that of the equatorial 150‐km echoes. Signal‐to‐noise ratio, velocity and spectral width are as high as 13 dB above noise, −5 to 35 m s<jats:sup>−1</jats:sup> and 2 to15 m s<jats:sup>−1</jats:sup>, respectively. The observed ‘necklace shape’ is first of its kind from Gadanki and the present observations have almost all characteristics of equatorial daytime 150‐km echoes. The Gadanki radar observations hence provide first experimental evidence on the occurrence of daytime 150‐km echoes outside the equatorial electrojet belt.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380580230606373401","@type":"Researcher","foaf:name":[{"@value":"A.
