| description | <p>Phase height measurements of low frequency radio waves
are used to study the long-term variability of the mesosphere over Europe.
Phase height measurements use a characteristic pattern in field strength
registration of radio waves interpreted as phase relations between sky wave
and surface wave to obtain the apparent height of the reflection point, the
Standard Phase Height (SPH). Based on this SPH-method a homogenized daily
series was generated since 1959 at Kühlungsborn. Improvements of the
measuring method show that the signal is significantly influenced by lower
atmospheric layers. Mesospheric reflection is not the exclusive source of
the measured behavior. Tropospheric influence can not be neglected. Taking
this into account one has to conclude that the strong coherency of the SPH
data to mesospheric heights is not as significant as previously assumed.</p> |
