Webb26 okt. 2024 · The diagnostics of the ionosphere was carried out on the basis of measuring amplitudes and phases of signals scattered by periodic irregularities in the altitude range of 50–130 km. For each heating session lasting 30 min, two ozone spectra were measured. These spectra were compared with the measured spectra the periods when heating was …

Webb21 juli 2024 · The lower boundary of the exosphere, where it meets the thermosphere, is called the thermopause. Its height above sea level ranges from 250-500 km up to 1000 km (310 to 620 miles), depending on solar activity. The thermopause is called the exobase, exopause, or critical altitude. Above this point, barometric conditions do not apply. thermomix nudel schinken gratin
