First Observation of a Strong Thermospheric 4.8‐Hour Tide and Its Impact on the Ionosphere Over Arecibo

Abstract We present an investigation of a prominent 4.8‐hr tidal wave observed at altitudes between 260 and 500 km, using data collected by the Arecibo incoherent scatter radar during March 17–20, 2015.
