Zusammenfassung:A radiophysical technique is proposed for calculating mesospheric temperatures using experimental measurements of the frequencies of resonant atmospheric oscillations (the acoustic cutoff frequency and the Brunt–Väisälä frequency). The partial reflection method is used to measure temperatures at sunset and an altitude of 75 km for days when the planetary index of geomagnetic storms was K p ≤ 1. These temperatures are in good agreement with data from other researchers.
