Statistical characteristics of PMWE observations by the EISCAT VHF radar
In the present paper ~ 32.5 h of EISCAT VHF PMWE observations were analyzed with focus on spectral properties like spectral width, doppler shift and spectral shape. Examples from two days of observations with weak and strong polar mesosphere winter echo (PMWE) signals are presented and discussed...

| description |
In the present paper ~ 32.5 h of EISCAT VHF PMWE observations were
analyzed with focus on spectral properties like spectral width, doppler shift
and spectral shape. Examples from two days of observations with weak and strong
polar mesosphere winter echo (PMWE) signals are presented and discussed in detail. These examples reveal a
large variability from one case to the other. That is, some features like an
observed change of vertical wind direction and spectral
broadening can be very prominent in one case, but unnoticeable in the other
case. However, for all observations a change of spectral shape inside the
layer relative to the incoherent background is noticed. |
