Two experimental sounding rockets were launched from Andøya Space Center
(Norway) devoted to investigate the phenomenon of polar mesospheric winter
echoes (PMWE). PMWE are relatively strong radar returns during winter,
observed at various frequencies (e.g. ≈ 50 MHz Maarsy or ≈ 224 MHz with
EISCAT). Despite possible tracing capabilities for dynamics in the Meso-
sphere over a wide annual and altitudinal extend, the formation process is
still not understood. To clarify the formation mechanism and proof theories,
an experimental setup consisting of two rocket payloads were designed. Aim-
ing for measuring neutral air temperature, relative and absolute densities of
plasma constituents (electrons, ions, charged aerosols), neutral air and trace
gases as well as turbulence. In-situ measurements were complemented by
ground based measurements of multiple radars and lidars.
We show results from contemporaneous multi instrumental in-situ measure-
ments and ground based observations based on the first part of the PMWE-
Project and discuss them in the context of most relevant theories.
