| Zusammenfassung |
| HF sounding of the mesosphere was first
carried out at SURA in summer 1994 at frequencies in the range 8–9 MHz using one
of the sub-arrays of the SURA heating facility. The observations had a range
resolution of 3 km. Almost all measurements indicated the presence of strong
radar returns from altitudes between 83 and 90 km with features very similar to
VHF measurements of mesopause summer echoes at mid-latitudes and polar mesopause
summer echoes. In contrast to VHF observations, HF mesopause echoes are almost
always present. |
